    Galileo deals 4 of a kind

    An Ariane 5 heavy-lift rocket launched four full operational capability (FOC) Galileo satellites on Nov. 17, accelerating deployment of the new satellite navigation system.

    The rocket carried Galileo satellites 15–18 from Europe’s Spaceport in Kourou, French Guiana, into space, releasing the first pair 3 hours, 25 minutes after liftoff, while the second separated 20 minutes later.

    All four are at their target altitude, after a smooth release from the new dispenser designed to handle four satellites.

    Over the next few days, engineers will nudge the satellites into their final working orbits and begin tests to ensure they are ready to join the constellation. This is expected to take six months or so.

    This mission brings the Galileo system to 18 satellites.

    The satellites already in orbit will allow the European Commission to declare the start of initial services, expected by year’s end.

    The previous 14 satellites were launched two at a time using the Soyuz–Fregat rocket.

    Galileo FOC-M6 satellites. The 15th to 18th satellites were built by prime contractor OHB System in Bremen, Germany, with the payloads supplied by UK-based Surrey Satellite Technology Ltd., owned by Airbus Defence and Space.

    The satellites weighed 714, 715, 714 and 715 kg. at launch, respectively, and were placed in a circular medium Earth orbit (MEO) in Plane C, at an altitude of 22,922 km. and an inclination of 54.57 degrees. They will subsequently be moved to their operational orbit at an altitude of 23,222 km.

    “Now that we can rely on the powerful Ariane 5, we can anticipate the quicker completion of Galileo deployment, permitting the system to enter full operation,” said Paul Verhoef, ESA’s director for the Galileo Programme and Navigation-related Activities.

    Two additional Ariane 5 launches are scheduled in 2017 and 2018. The full system of 24 satellites plus spares is expected to be in place by 2020.

    “With this 75th successful launch in a row, Ariane 5 sets a new record within European developed launchers and proves once more its reliability,” said Daniel Neuenschwander, ESA’s director for Launchers.

    “Now that we can rely on the powerful Ariane 5, we can anticipate the quicker completion of Galileo deployment, permitting the system to enter full operation,” said Paul Verhoef, ESA’s Director for the Galileo Programme and Navigation-related Activities, following the successful launch Nov. 17 of four satellites at once.

    Verhoef made the following further remarks to GPS World regarding Galileo’s future. The full text of his article will appear in the December issue.

    “The European Union is set to declare Galileo operational for initial services at the end of this year, bringing the system to the point where it can start serving users.

    “November’s launch has been years in the making, employing a specially customized variant of Europe’s heavy-lift workhorse rocket called the Ariane 5 ES (Evolution Storable) Galileo. It has more powerful lower stages and a reignitable upper stage, first used in 2008 to supply the low-Earth orbiting International Space Station.

    “Two further Ariane 5 SE Galileo flights are planned to follow, one each for the remaining orbital planes.

    “This new launcher design, adapted beginning in 2012 for Galileo, carried a lower mass payload — four fully-fuelled 738-kg Galileo satellites plus their supporting dispenser — but hauled it to the much higher altitude of medium-Earth orbit, 23,522 km. This precisely targeted orbit actually lies 300 km above the Galileo constellation’s final working altitude, leaving Ariane’s upper stage in a stable graveyard orbit, while the quartet of satellites maneuver themselves down to their final height.

    “The four-satellite dispenser, the interface between the satellites and its launcher, is a wholly new design by Airbus Defence and Space. Its first role is to hold the satellites safely in position during their orbital flight and then to gently release them in separate directions. Its structure has been specially tuned to prevent harmful oscillations being triggered by the vibration and noise of launch. Its design was validated using complex finite -element-modeling software, followed by practical testing of the dispenser together with dummy satellites.

    Launcher. “Ariane’s interstage Vehicle Equipment Bay, hosting the rocket’s avionic brain, underwent a redesign to reduce mass. Engineers also had to take into account this Ariane ES version’s flight time, much longer than any of its predecessors, more than four hours in all. This involved a reworking of the launcher’s electronics and thermal subsystems, to ensure it maintains an optimal operational environment throughout a ballistic coast phase of more than three hours, between two firings of its EPS storable propellant upper stage.

    Ground Control. “This launch marked the first time that ESA carried out launch and early operations (LEOP) for four satellites simultaneously. Usually, simply shepherding a spacecraft through the first critical days in orbit is a demanding enough task. A combined team from ESA and France’s CNES space agency based in Toulouse will make contact, establish control, and then see the four satellites through their initial critical activities. Within the combined team, each position is paired with a counterpart from the other agency to provide three mixed shifts around the clock for these first crucial days. This same team has conducted all Galileo early operations to date alternately from Toulouse or ESA’s ESOC control center in Germany.

    “The work starts with an initial check of on-board health and attitude, progressing to ensure each satellite’s pair of 1 x 5-meter solar wings are deployed and tracking the Sun, and then to point their antennas back towards Earth. Next comes a series of thruster firings to set the satellites onto a drift course into their final orbit, at which point they can be handed over to the Galileo Control Centre in Oberpfaffenhofen, Germany, for routine operations, and to ESA’s Redu Centre in Belgium to commence a few months of detailed payload testing.

    Galileo at Your Service
    “Around the same time as this key launch, GSAT-210 and GSAT-211, the two previous satellites launched in May of this year, will have completed their in-orbit testing, allowing them to be formally certified as operational members of the constellation. The four new satellites should follow them into operational status by mid-2017. However, the Galileo system will reach initial operational status without these latest six satellites. The European Commission on behalf of the European Union expects to declare the system operational and ready to offer initial services before the end of this year.

    “This will mark a major milestone in the programme, awaited by many citizens in Europe and around the globe. Everyone with a Galileo-enabled receiver will be able to benefit from improved positioning, supplementing the already operational GPS constellation. ESA and the European GNSS Agency (GSA) have been working with European manufacturers of mass-market satnav chips and receivers to ensure that their products are Galileo-ready, offering detailed laboratory testing to close the loop between Galileo and industry.

    Transition. “In parallel to the declaration of initial services, there will also be an institutional change, as the GSA takes up its role overseeing the exploitation of Galileo. At the start of 2017, the formal handover of Galileo infrastructure will be initiated, targeted to conclude by the middle of the year. This mission includes not only the Galileo satellites in space but also the far-flung ground stations located on every continent, essential to the continued high-performance operations of the Galileo system. It also includes the two European Galileo control centers, with the signals overseen from Fucino in Italy and the platforms monitored from Oberpfaffenhofen, plus the communication infrastructure connecting them all together.

    Upgrade. “2017 will see the upgrade of various elements of the Galileo Ground Segment to reinforce its robustness, including updated releases to the Galileo Control Segment overseeing the satellites and the Galileo Mission Segment, overseeing the navigation signals. A new release of elements of the Galileo Security Facility, for security monitoring of the system, as well as the secure Public Regulated Service, will be deployed at the two Galileo Security Monitoring Centres.  The Galileo Ground Segment will gain a sixth tracking telemetry and control facility, for monitoring the satellite platforms in Papeete, Tahiti, and additional processing chains for increased redundancy will be deployed across the Uplink Stations in Kourou, Reunion and Noumea used to update the navigation message information. Similar redundant chains will be finalized for all 15 current Galileo Sensor Stations, which perform continuous collection of Galileo signals to identify the tiniest clock error or satellite drift.”

  • Arianespace ready to roll out 4-satellite launcher for Galileo

    Arianespace ready to roll out 4-satellite launcher for Galileo

    Arianespace has entered the final phase of preparations for its next Ariane 5 launch — the company’s first heavy-lift mission to orbit satellites for Europe’s Galileo navigation constellation.

    During activity in the Spaceport’s Final Assembly Building, Arianespace “topped off” the Ariane 5 launcher with installation of the payload fairing over the four Galileo spacecraft and their payload dispenser.

    With Ariane 5 complete, it is being readied for rollout to the Spaceport’s ELA-3 launch complex in advance of its Nov. 17 flight, set for liftoff at 10:06:48 a.m. local time in French Guiana.

    This mission — designated Flight VA233 in Arianespace’s numbering system — will deploy the quartet of Galileo spacecraft over the course of a nearly four-hour flight.

    For the Galileo program, Arianespace is using the Ariane 5 ES version with an enhanced storable propellant upper stage that allows for reignition and long coast phases during the mission.

    These upgrades maximize the launcher’s performance for deploying the Galileo spacecraft — which will have a combined mass of 2,865 kg at liftoff — two at a time into a circular medium-Earth orbit.

    As a European initiative to develop a new global satellite navigation system under civilian control, Galileo will offer a guaranteed, high-precision positioning service that will end Europe’s dependence on the American GPS system.

    The Galileo constellation will comprise 24 operational satellites, along with spares. Arianespace already has deployed 14 Galileo in-orbit validation and full operational capability spacecraft from French Guiana on seven medium-lift Soyuz missions, along with performing two other Soyuz flights from the Baikonur Cosmodrome in Russia with the GIOVE-A and GIOVE-B experimental satellites.

    Galileo is funded by the European Union. It features innovative technologies developed in Europe for the benefit of all citizens. The European Commission holds overall responsibility for Galileo’s management and implementation, with the European Space Agency assigned design and development of the new generation of systems and infrastructure.

    The Galileo satellites on Arianespace’s Flight VA233 are sized at 2.7 x 1.2 x 1.1 meters and were built by OHB System in Bremen, Germany, while their navigation payloads were supplied by UK-based Surrey Satellite Technology Limited (SSTL), which is 99 percent owned by Airbus Defence and Space.

    All four Galileo satellites are mated to the dispenser in readiness for the upcoming launch.

    The launch campaign for the Nov. 17 Galileo launch from the French Guiana spaceport has entered its latest phase of preparations, with the mission’s four satellite passengers being installed on their multi-payload dispenser system.

    The activity — performed in the Spaceport’s S3B clean room — clears the way for the satellites’ integration as a single unit atop the heavy-lift Ariane 5, which was transferred earlier this week from the Launcher Integration Building to the Final Assembly Building, where payload integration is set to occur, according to launch contractor Arianespace.

    Designated Flight VA233, the upcoming mission is scheduled for a Nov.17 liftoff from the Spaceport in French Guiana at precisely 10:06:48 a.m. local time, with the four Galileo satellites subsequently being deployed into circular orbit during a mission lasting just under four hours.

    Flight VA233 will mark Arianespace’s first use of Ariane 5 to loft spacecraft for Europe’s Galileo global navigation system, following seven previous missions with the medium-lift Soyuz — which carried a pair of satellites on each liftoff. Flight VA233 is scheduled as the company’s ninth launch overall performed so far in 2016, as well as the sixth this year using the heavy-lift workhorse. Arianespace’s full launcher family is rounded out by the light-lift Vega.

    Galileo is an important infrastructure program for Europe, creating a civil global satellite navigation system that provides highly accurate positioning with great precision and reliability.

    It is funded and owned by the European Union, with overall responsibility for management and implementation held by the European Commission. Design and development of the new generation of systems and infrastructure has been assigned to the European Space Agency.

    OHB System in Bremen, Germany, built the Galileo satellites, which are sized at 2.7 x 1.2 x 1.1 meters, while their navigation payloads were supplied by UK-based Surrey Satellite Technology.

  • 4 Galileos ‘topped off’ for November launch

    4 Galileos ‘topped off’ for November launch

    Fueling operations have begun with the four Galileo spacecraft to be launched Nov. 17 from French Guiana. This will be launch contractor Arianespace’s first launch using its Ariane 5 rocket to deploy Europe’s constellation of navigation satellites.

    The fueling activity is now underway in the Spaceport’s S3B payload preparation facility. One of the first to be processed is named “Antonianna,” after an Italian child who won a European Commission Galileo drawing competition — with one winner selected from each member state of the European Union.

    Weighing between 715 kg. and 717 kg. each, the quartet of Galileo satellites will have a combined liftoff mass of 2,865 kg., and they will be deployed by Ariane 5 into circular orbit during a mission lasting just under four hours.

    The Ariane 5 launch, designated Flight VA233 in Arianespace’s numbering system, is set for a morning departure from the Spaceport on Nov. 17 at an exact liftoff time of 10:06:48 a.m. in French Guiana (13:06:48 p.m. Universal Time — UTC).

    Flight VA233 will mark Arianespace’s first use of its heavy-lift Ariane 5 to loft Galileo satellites, following seven previous missions with the company’s medium-lift Soyuz. The Soyuz vehicles carried a pair of Galileo spacecraft on each flight, delivering a total of 14 navigation satellites into orbit since 2011.

  • Intergeo 2016 is buzzing

    Intergeo 2016 is buzzing

    Yes, there are drones everywhere. Drones of every size from mini electronic insects to a rather nice Zeppelin remake that is cruising around Hall 4 at the Hamburg Messe. Will Intergeo 2016 mark “peak drone?” I’m thinking not.

    The two main drivers of this year’s Intergeo conference are digitization and smart data, including Building Information Modelling (BIM). Hamburg itself is working at becoming a smart city, and the role of geodata and geospatial information is key to achieving the city planners dream of fast and efficient services for its “e-citizens.”

    Remarkably, this key role is not always initially appreciated by ‘smart city’ innovators. Nigel Clifford, CEO of the UK’s venerable Ordnance Survey pointed out in the plenary conference session that the perception of the value derived from geospatial data is changing as location data “uniquely unlocks value in others’ data.” He also coined the term Geovation – something we will be hearing more about in years to come I am sure.

    At the Trends in GNSS Positioning session, I was surprised to hear (or at least this how the translation came over) that both Herbert Landau of Trimble Terrasat GmbH and Bernhard Richter of Leica Geosystems were suggesting that if you bought their latest RTK/ PPP systems, you would never need to buy another one! Both had similar reasons: their systems had a “gazillion channels” for receiving positioning data, were equipped for multiple communication modes (terrestrial and satellite-based), had low power requirements but powerful computing on board, were easily portable, and the fact that in the near future some 120-140 GNSS satellites would be in the sky. This plethora of signals and multiple frequencies will allow a whole range of new possibilities.

    Along these lines, NavCom Technology announced the release of its Onyx multi-frequency GNSS OEM board. Offering integrated StarFire/RTK GNSS capabilities, Onyx features 255-channel tracking, including multi-constellation support for GPS, GLONASS, BeiDou and Galileo.

    Galileo Coming On Strong. Talking of new signals in space, what is the news on Galileo Initial Services?  Reinhard Blasi of the European GNSS Agency (GSA) gave an update at the conference, and we can expect to see Initial Services by “the end of 2016.” Reinhard thinks that once services are established, Galileo will be in a leading position as GPS is between system upgrades and the E5 signal has some unique features.

    Galileo for Mass Market. This belief was supported at the ceremony for the Young Surveyors competition organised by the Council of European Geodetic Surveyors (CLGE) at the end of the first day at Intergeo. In the Galileo, EGNOS and Copernicus category the winner was Cecile Deprez from the University of Liege. She had looked at the possibilities for greater precision in mass market applications that might be possible by accessing the Galileo E5 AltBLOC. And the answer is yes it can. In fact she described the performance as “outstanding” compared to other GNSS signals. Which is probably fair comment.

    See what you think. Along with Desprez “Relative Positioning with Galileo E5 AltBOC Code Measurements,” you can find all the papers entered for the award on the CLGE website: http://www.clge.eu.

     

  • Ariane 5 ready for first payload of Galileo satellites

    Ariane 5 ready for first payload of Galileo satellites

    The first Ariane 5 launcher to orbit Galileo navigation satellites has completed its initial build-up in French Guiana, continuing preparations for Arianespace’s Nov. 17 mission from the spaceport to deploy four more Galileo satellites, according to launch contractor.

    During activity in the Spaceport’s Launcher Integration Building, the heavy-lift vehicle for Arianespace Flight VA233 underwent the assembly process that began by mating Ariane 5’s two solid propellant strap-on boosters with the main cryogenic stage.

    The next step was integration of the launcher’s vehicle equipment bay as well as the installation of Ariane 5’s EPS storable propellant stage.

    From launcher integration to final assembly

    After completion of verifications and systems checkout by production prime contractor Airbus Safran Launchers, the Ariane 5 will be moved to the Spaceport’s Final Assembly Building — where Arianespace takes authority for payload integration and launch.

    The EPS storable propellant upper stage is powered by a re-ignitable engine that operates with MMH and N2O4 propellants. It differentiates Flight VA233’s launcher from the Ariane 5 ECA versions, which have a cryogenic upper stage and are typically used on Arianespace missions to geostationary transfer orbits with telecommunications satellites.

    For Flight VA233, the Ariane 5 ES will carry the quartet of Galileo satellites (weighing 738 kg. each) and their 447-kg. dispenser system to medium-Earth orbit, for deployment at an altitude of approximately 23,222 km.

    The upcoming Ariane 5 launch will mark the initial utilization of Ariane 5 in deploying Galileo constellation satellites. Flight VA233 will continue Arianespace’s support of the global positioning satellite system, following seven missions performed with the company’s medium-lift Soyuz that carries a pair of Galileo spacecraft on each flight. Seven Soyuz missions have delivered a total of 14 navigation satellites into orbit since 2011.

    Galileo is a key effort for Europe, offering highly accurate positioning with great precision and reliability via a civil global satellite navigation system. The program is funded and owned by the European Union, with overall responsibility for management and implementation held by the European Commission. Design and development of the new generation of systems and infrastructure has been assigned to the European Space Agency.

    The spacecraft to be launched on Flight VA233 were built by OHB System in Bremen, Germany, with their navigation payloads provided by Surrey Satellite Technology in the United Kingdom. Airbus Defence and Space developed the dispenser system that will carry and deploy the satellites from Ariane 5.

  • Rocket readied for 4 at once for Galileo

    The first rocket to loft four global positioning satellites at once has begun its build-up at the European Space Agency’s Spaceport in French Guiana.  The milestone mission, scheduled for Nov. 17, will carry four Galileo satellites into orbit.

    This launcher  began the integration process with the cryogenic core stage’s positioning over a mobile launch pad, followed by integration of the vehicle’s two solid propellant boosters. Designated as Flight VA233, the Ariane 5 rocket is being assembled inside the Spaceport’s Launcher Integration Building. Once completed, it will be moved into the Final Assembly Building  for installation of the four Galileo spacecraft.

    Arianespace already has orbited 14 Galileo spacecraft, all lofted in pairs on seven missions aboard the company’s medium-lift Soyuz launcher, with the most recent conducted last May.

    For its maiden Ariane 5 mission at the service of Galileo, Arianespace’s workhorse heavy-lift vehicle will be equipped with a dispenser system that secures the quartet of Galileo satellites in place during ascent, and deploys them in rapid sequence at a targeted release altitude of 23,222 kilometers.

    The four spacecraft were built by OHB System in Bremen, Germany, with their navigation payloads provided by Surrey Satellite Technology in the U.K.

  • Portrait of Galileo: European groups say constellation is ready for service

    galileo-programme-update-ion-2016-vf1
    From a Galileo programme update presented at ION GNSS+ 2016.

    Spokespersons from the European Commission, the European Space Agency and the European GNSS Agency (GSA) built a portrait of Galileo at the ION GNNS+ conference of a satellite constellation ready to step upon the world stage. Meanwhile, four new satellites are scheduled to launch aboard a single Ariane rocket on Nov. 17, leading to declaration of initial services by the end of the year.

    With 14 satellites in orbit, 12 ordered and four on the launchpad, system operators feel confident in predicting initial operational capability by the end of this year. They already have their eyes set on additional service distinctions driven by emerging new requirement from user communities:

    • Authentication, for applications requiring trusted position and timing information; a key feature to enable new types of commercial applications such as pay-as-you-drive car insurance, road user charging (highway tolling) and access to mobile content
    • A robust timing service
    • Advanced receiver autonomous integrity monitoring (ARAIM)
    • Emergency warning services
    • A Galileo regional service
    • Ionosphere prediction service
    • SBAS authentication

    Key areas identified to drive Galileo evolution included timing for 5G telecoms, digital video broadcasting and autonomous vehicles.

    GNSS will increasingly be used not as a sole localization solution but deeply integrated with several positioning networks and sensors to work across an array of contexts, according to the several European experts. However, despite growing alternative solutions, GNSS will remain core as the most cost-effective global positioning technology, especially for outdoor location information and larger scale applications.

    Looking at the future, for the majority of mass-market applications, an accuracy of a few meters is sufficient, but key strategic users will need (some already need) better performance that must be satisfied. Galileo evolution has to offer enhanced performance, enabling new and strategic applications, to remain at the center of the positioning and timing market.

    Galileo’s evolutionary targets to improve in the future were listed as: a ranging accuracy between 2 and 5 times that to be declared at Galileo FOC (in 2020?); position accuracy down to sub-meter level; timing accuracy increased by two times over Galileo FOC; better support of spoofed users; enhanced authentication (nav message authentication) and anti-replay.

    New Operations Center in Spain. The European GNSS Agency (GSA) is gearing up to assume its operational role for Galileo in early 2017. During the summer the GSA formally accepted their Loyola de Palacio facility in Madrid, Spain that houses the European GNSS Service Centre (GSC).

    GSA already oversees the operation and service provision for the European Geostationary Navigation Overlay Service (EGNOS) (since 2015) along with managing the security accreditation and general security provision for both programmes.

    Since 2013, the core team at GSC has been providing limited services and working as a precursor to GSC v1. Its key work includes supporting the lead-up to Galileo Initial Services provision, along with operating the GSC Helpdesk, disseminating orbital products to the Search and Rescue (SAR) community, supporting GNSS-related research and industrial activity and monitoring user satisfaction. Once operational, GSC v1 will be connected to the Galileo core system, thus enabling the long anticipated Commercial Service. This service is expected to enter operations by mid-2017.

    Galileo Hackathon in Berlin. The GSA invites coders, app developers and other interested parties to a two-day event in early November, the Galileo Hackathon. “Be one of the first to use Galileo!” The online invitation seeks those who want to shape the future of Location-Based Services (LBS) and Geo-IoT to become pioneer developers, showcase their skills, connect with the Geo-IoT app-dev community, and win prizes. November 3–4 in Berlin.

  • Galileo Initial Services looming

    With Galileo Initial Services at last on the horizon and a quadruple satellite launch scheduled for November, here’s hoping that Europe’s GNSS constellation will be delivering limited, but reliable, global PNT services before the year is out.

    The four Galileo satellites for Arianespace’s first Ariane 5 mission for the constellation are being prepared at ESA’s launch facility in French Guiana. The flight is scheduled for 17 November. However neither these four new satellites, nor the two orbited in May, are required to deliver Galileo Initial Services, which should be launched officially some time in November. Fingers crossed.

    The European GNSS Agency (GSA) is gearing up to assume its operational role for Galileo in early 2017. During the summer the GSA formally accepted their Loyola de Palacio facility in Madrid, Spain that houses the European GNSS Service Centre (GSC). This is a significant milestone in the development of the programme and its service provision as Galileo’s “door to the GNSS world” as GSA Executive Director Carlo des Dorides described the facility at the handover ceremony.

    GSA already oversees the operation and service provision for the European Geostationary Navigation Overlay Service (EGNOS) (since 2015) along with managing the security accreditation and general security provision for both programmes.

    The GSC offers over 1,100 square metres of space and currently employs over 40 people. Since 2013, the core team at GSC has been providing limited services and working as a precursor to GSC v1. Its key work includes supporting the lead up to Galileo Initial Services provision, along with operating the GSC Helpdesk, disseminating orbital products to the Search and Rescue (SAR) community, supporting GNSS-related research and industrial activity and monitoring user satisfaction. Once operational, GSC v1 will be connected to the Galileo core system, thus enabling the long anticipated Commercial Service. This service is expected to enter operations by mid-2017.

    Once the Galileo Operations Contract is awarded and Initial Services officially declared, the GSC is expected to see a significant increase in staff.

    Also in the summer CNES President and France’s inter-ministerial coordinator for European satellite navigation programmes Jean-Yves Le Gall was elected as the new chair of the GSA Administrative Board with Mark Bacon, representing the United Kingdom, elected as deputy chair.

    “I am honoured to have been elected chair of the GSA Administrative Board, with Galileo now poised to enter its operational phase,” said Le Gall. “This election confirms the desire of Member States to join forces on the cusp of a prolific period for European space as we move Galileo towards full operational capability.”

    Brexit blues?

    Mark Bacon added “I am very pleased to have been elected to work with the Board and I look forward to helping the GSA deliver on the Galileo and EGNOS programmes over the coming years.”  However the UK’s decision to leave the EU (Brexit) must make his position rather uncomfortable – and temporary – to say the least.

    The GSA Administrative Board is composed of representatives from each EU Member State, the European Commission, and the EU parliament. The Board meets three times per year to ensure that the Agency performs its tasks correctly. As things stand if the UK is no longer an EU Member State it must lose its representative(s) on the advisory board.

    However, the relationship between the UK and EU space programmes is, of course, subject to the Brexit negotiations. The UK will almost certainly remain a member of the European Space Agency (ESA) as this is a pan-European body not an EU agency, however when it leaves the EU the country will have to renegotiate terms if it wants to continue to participate in the key EU programmes such as Galileo GNSS and Copernicus Earth Observation system.

    The ESA is autonomous from the EU and should not be directly affected by Brexit confirmed Jean Bruston, head of ESA’s EU policy office at a media briefing in mid-September. But “As soon as it [Britain] is leaving the EU it is not participating in these programmes [Galileo / Copernicus] any longer,” he observed.

    In addition, UK-based companies hold contracts worth tens of millions of euros from ESA to supply hardware for the Copernicus and Galileo GNSS. “If nothing changes [and Brexit goes ahead], we would have to stop these contracts,” said Bruston bluntly.

    Of course, Britain could still contribute to Galileo and Copernicus if it negotiated a third-party agreement with the EU, as Norway and Switzerland (both non EU members) have done. The down side is that this may take some time to initiate, let alone complete, and if Britain sticks to its guns on issues such as free movement of people then the likelihood of a successful outcome for the UK is not high.

    In an interview with French media ESA director-general Jan Woerner reinforced Bruston’s views saying that “the UK will remain a member state of ESA, this is very clear” but also continuing “As we are also dealing with European programmes like Copernicus and Galileo, and also the question of UK citizens working on the continent and all these legal issues, we have to take this into account.”

    EU opportunity

    Many in ‘continental Europe’, as we Brits so often condescend to describe our fellow Europeans, will be more than happy to see the U.K. no longer participating in deciding key aspects of EU space and other policy areas.

    It is no coincidence that the European Commission has become much more vocal on plans for a European defence force since the Brits announced their departure. The U.K. has long been opposed to the concept of an ‘EU Army.’ However planning and military cooperation between Member States outside normal NATO channels has been increasing over many years. The small and discreet (so discreet that I didn’t realise the exact location of its HQ in Brussels until the recent terrorist incidents meant burly Belgian paratroopers were stationed outside and I asked them what they were guarding. Has to be said they were not discreet!) has seen its budget frozen for the last five years, but this may now change.

    The interface of EU space and defence policy – in particular ‘dual use’ issues – will also become simpler without the U.K.’s protests. A leaked draft of the upcoming EU Space Policy communication talked directly of dual-use synergies to reinforce security from space, in particular to reduce costs and improve efficiency, and that the next generation of EU GNSS and Copernicus programmes should be designed from the start to be more relevant for security purposes. Defence-related research is also slated for future Horizon 2020 calls.

    The draft policy document also underlines that with EU space programmes becoming fully operational, building stability, trust and confidence in users is a key objective. Current services must be fully deployed and their long-term continuity and evolution assured. This continuity should be driven by user needs and take into consideration the mid-term (hardly mid-term for Galileo!) evaluation of the programmes that should happen in 2017. For Galileo and EGNOS, the document looks to improvements in the current services, including greater robustness and performance, and provision of additional services, such as regional or timing services.

    California dreaming

    So with Brexit what is the U.K.’s GNSS – and space-related – industry and research community to do? Of course many of the UK industrial players are multi-national companies and internal transfer of people and/ or projects will overcome many issues. And bi-lateral collaborative agreements on exchange of talent and ideas between partners can also achieve the same results for smaller companies and research groups. However not having a seat in the policy process and the development of programmes will put ‘UK plc’ at a distinct disadvantage in my opinion.

    But U.K. leaders say that Brexit is an opportunity to be seized and that the U.K. should be looking to sell  goods and services in other global markets than the EU. Which is something most U.K. industry has been doing since trade/ time began. And in my experience U.K. business leaders have always been much more eager to go jump on a plane to the States or Australia than go visit their European neighbours – something to do with our renowned national language skills perhaps?

    Space is no exception – and one that has been shown to be a success in recent times. A helping hand is provided by InnovateUK, the U.K.’s government innovation agency, that is organising its third ‘Space Mission UK’ to the US in November. These are trade and investment missions specifically designed to support U.K. start-up companies to build world-leading space and satellite application businesses.

    Space Mission 1 visited Utah, LA and Silicon Valley in August 2015 and Space Mission 2 landed in Houston in November 2015. Space Mission 3 will visit San Francisco and LA from 5-11 November this year.

    Mission programmes are varied but typically include visits to companies working at the forefront of the sector, networking opportunities with investors and corporate venture people interested in space, visits to incubators, accelerators and technology hubs, and masterclasses on pitch development, business culture and market entry.

    The previous two Space Missions have had immediate impact for the companies involved, including securing over £1 million in investment, and initiating collaborations with major organisations such as NASA and (ironically) ESA, and winning contracts with the UK Ministry of Defence at home.

    GNSS-related companies in previous missions include Arralis who build high-end semiconductor chips but have also been funded to develop novel GNSS antennas, and an exciting data fusion start-up – Gyana – that takes complex inputs from multiple data sources, including satellite, to build simple to understand 3D situational images. The founder of the business, engineering graduate Joyeeta Das, has raised US $1.1m since the mission.

    You can find a complete list of companies who have participated on the previous missions here.

    The selection for Space Mission 3 has closed and I am told there is at least one GNSS applications company that has been chosen to be on the plane in November. Good luck to them all!

    Google emergency LBS upgrade

    E112 is a location-based version of the 112 universal European emergency number, where the telecommunication operator transmits location information to the emergency centre in parallel to the call itself. With more than 70 percent of calls to emergency services coming from mobile phones, getting help fast and efficiently to the caller can be challenging if they don’t know where they are. Now, in a major step forward for implementation, Google has created and rolled out in two European countries (U.K. and Estonia) its Emergency Location Service on Android, with other regions to follow. The feature, when supported by the caller’s network, sends the phone’s location to emergency services when the 112 (or equivalent) emergency number is dialed.

    Emergency Location Service is supported by more than 99 percent of existing Android devices (version 2.3 and above) through Google Play services. The service activates when supported by the mobile network operator or emergency infrastructure provider.

    The new geographical location system claims to identify the source of a mobile phone emergency call to typically within 0.003 square kilometres (less than half the size of a football field) instead of a current average of around 12 square kilometres.

    When an emergency call is made with an enabled Android smartphone, the phone automatically activates its location service and sends its position by text message to the 112 service. This usually takes less than 20 seconds. This text message is not visible on the handset and is not charged for.

    And the first European Galileo-ready smartphone has been launched with the Aquaris X5 Plus smartphone, produced by the Spanish technology company BQ, and based on the Galileo-supported Qualcomm Snapdragon 652 processor with Galileo capability accessible via a software update to be released in Quarter 4 2016.

    U.S.-based Qualcomm announced in June that it was adding support for Galileo across its Snapdragon processor and modern portfolios for smartphone, computing, automotive and IoT applications.

    As well as Galileo capability, the Aquaris X5 Plus is powered by the latest Google Android OS and has all the usual features of a top end smart phone including 16 mega pixel ‘back’ camera and support for 4k video recording with a stabiliser and fingerprint recognition for added security.

    If you want to take the pulse of the GNSS user technology industry and keep up with the latest trends then you’ll need to get your hands on the GSA’s GNSS User Technology Report due out at the beginning of October.

    The 2016 report will be launched on 4 October as part of the Horizon 2020 Space Information Days in Prague. This two-day GSA-hosted event will introduce the third call for GSA-funded Horizon 2020 research and innovation proposals for Galileo and EGNOS.

    The document will take an in-depth look at the latest state-of-the-art GNSS receiver technology, along with providing expert analysis on the various trends that are defining the future global GNSS technology landscape. The report will focus on three key areas: mass market solutions; transport safety and liability-critical solutions; and high precision, timing and asset management solutions.

    Pulsar GNSS for deep space

    The use of pulsars, highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation with a very precise period, have been potential candidates for a deep space navigation system for many years. Now a paper from the U.K.’s National Physical Laboratory (NPL) and the University of Leicester shows that pulsars can be used to obtain position along a particular direction in space to an accuracy of two kilometres in the direction of the pulsar. Furthermore such a technology could operate autonomously and greatly increase the number and capabilities of space missions, the paper claims.

    To calculate their position a space craft would need to carry a small X-ray telescope. The method uses X-rays emitted from pulsars, which can be used to work out the position of a craft in space in 3 dimensions to an accuracy of 30 km at the distance of Neptune. Certain types of pulsar, called ‘millisecond pulsars’, emit pulses of radiation with the regularity and precision of an atomic clock and therefore could be used much like GNSNS in space.

    The paper, published in Experimental Astronomy[1], details simulations undertaken using data, such as the pulsar positions and a craft’s distance from the Sun, for an ESA feasibility study of the concept. The simulations took these data and tested the concept of triangulation by pulsars with current X-ray telescope technology and state-of-the art position, velocity and timing analysis. This generated a list of usable pulsars and measurements of how accurately a small telescope can lock onto these pulsars and calculate a location.

    The key finding was that at a distance of 30 astronomical units – the approximate distance of Neptune from the Earth – an accuracy of 2km or 5km can be calculated in the direction of a particular pulsar (PSR B1937+21) by locking onto the pulsar for ten or one hours respectively and that by locking onto three pulsars, a 3D location with an accuracy of 30km can be calculated.

    This is an improvement on the current navigation methods of the ground-based Deep Space Network (DSN) and European Space Tracking (ESTRACK) network as it could be autonomous with no need for Earth contact for months or years, if an advanced atomic clock is also on the craft. Also ESTRACK and DSN can only track a small number of spacecraft at any one time. It is also possible that the pulsar technique could be quicker.

    Dr Setnam Shemar from NPL commented: “How these [space]craft navigate will in future become a limiting factor to our ambitions. The cost of maintaining current large ground-based communications systems based on radio waves is high and they can only communicate with a small number of craft at a time. Using pulsars as location beacons in space, together with a space atomic clock, allows for autonomy and greater capability in the outer solar system.”

    This simulation uses real-world technology and proves its capabilities for this navigation task. The X-ray telescope can be launched into space due to its low weight and size and it will be flown on a mission to Mercury in 2018. Could we be seeing the emergence of a navigation technology that can enable a new era of space exploration?

    And with that look into the future it is time to say “adios” to this column. From now on my EAGER dispatches will be sprinkled through other GPS World imprints and platforms. I’ll be at the global geospatial fun-fest that is Intergeo in Hamburg in October and sniffing around the first Galileo ‘hackathon’ in Berlin in early November, so I hope to see many of you at those and subsequent Euro-GNSS events in the future.

    A bientot as they say in these parts.

  • McMurdo launches emergency beacons with GPS, GLONASS, Galileo

    McMurdo launches emergency beacons with GPS, GLONASS, Galileo

    Emergency preparedness company McMurdo has launched a new family of Emergency Position Indicating Radio Beacons (EPIRBs) that will accelerate the search-and-rescue process by combining multiple frequencies — including GNSS — into a single EPIRB product.

    The McMurdo SmartFind and Kannad SafePro EPIRBs are distress beacons that can support each of the four frequencies used in the search-and-rescue process: GNSS for location positioning, 406 MHz and 121.5 MHz for beacon transmission, and Automatic Identification System (AIS) for localized connectivity.

    The multiple-frequency capability will ensure faster detection, superior positioning accuracy, greater signal reliability and, ultimately, accelerated rescue of people or vessels in distress, the company said.

    Expanded satellite connectivity. McMurdo SmartFind and Kannad SafePro EPIRBs have a multiple GNSS satellite constellation receiver supporting Galileo (once the constellation is fully operational), GPS and GLONASS — from a single beacon. Advanced GNSS data processing results in faster detection of positioning coordinates and enhances the accuracy of the emergency location.

    Most of today’s EPIRBs use 406 MHz and 121.5 MHz frequencies via satellite communication to provide location and positioning data to global search and rescue personnel who may be several hundred miles away.

    The additional AIS channels on the new McMurdo SmartFind G8 AIS and Kannad SafePro AIS EPIRBs will send position signal information to standard AIS electronic equipment on nearby vessels for complementary, local tracking and rescue capabilities. This global and local rescue capability will result in quicker signal detection and faster response times.

    The McMurdo SmartFind and Kannad SafePro EPIRBs are part of McMurdo’s comprehensive search and rescue ecosystem. As the world’s provider of an end-to-end search and rescue ecosystem — including distress beacons, satellite ground stations, mission control and rescue coordination systems, and rescue response products — McMurdo builds, integrates and tests products as part of a live search and rescue system. This ensures greater cohesion between distress signal transmission and reception so that beacon owners can feel confident that their signals will get to search and rescue authorities quickly.

    MEOSAR compatibility. The McMurdo SmartFind and Kannad SafePro EPIRBs are designed to be fully compatible with MEOSAR, the next generation of the Cospas-Sarsat international search-and-rescue satellite system that has helped to save over 40,000 lives since 1982. MEOSAR will increase the speed and accuracy of beacon signal detection and location with new MEOSAR ground network infrastructure and additional MEOSAR satellites.

    When fully deployed, a MEOSAR-compatible beacon can be located with an accuracy of location within 100 meters (328 feet), 95 percent of the time — and within five minutes of distress signal activation, all without reliance on GNSS.

    McMurdo manufactures approximately 50 percent of the world’s MEOSAR infrastructure and is also leading the design of additional MEOSAR-capable beacons under the European Union’s Horizon 2020 Research and Innovation Program’s HELIOS project.

    “McMurdo’s new EPIRB announcement is a major step towards achieving a unified search-and-rescue vision,” said Bruce Reid, CEO of the International Maritime Rescue Federation. “The convergence of products and systems whether AIS and 406 MHz or maritime domain awareness and search and rescue, respectively, will require a comprehensive understanding of the entire search and rescue ecosystem. I look forward to seeing more McMurdo solutions and innovations that will shape the search and rescue industry for years to come.”

    The McMurdo SmartFind and Kannad SafePro distress beacons support beacon transmission, GNSS for location positioning, and AIS for localized connectivity.
