  • What the ‘Brexit’ vote means for EU space programmes, Galileo

    What the ‘Brexit’ vote means for EU space programmes, Galileo

    A Kingdom Divided: Whither EU Space Programmes?

    Brexit-WGood grief, it has been a wild week or two. I was hoping that I wouldn’t need to talk about the incredible, excruciating UK referendum on European Union membership, but as the result has gone to the “leave” campaign, I feel obliged to pick over the wreckage.

    What does a UK exit from the EU mean for EU space programmes and Galileo in particular?

    First: UK involvement in the European Space Agency (ESA) should be unaffected by the exit of the UK from the European Union as this is a separate institution. However, one could argue that non-membership of the EU might diminish its voice and could require a higher financial contribution.

    Bids for the next Galileo satellite purchase contracts are due to be submitted in mid-July, and the European Commission has indicated that it will consider them purely on commercial terms. This is good news for the OHB System and Surrey Satellite Technology Limited (SSTL) consortium. And also for the Commission. If I were a betting man, I’d still wager the house on the incumbent consortium winning the contract to provide the remaining satellites required to provide a sustainable, 24/7 operational constellation for 1st generation Galileo. There would, in my opinion, be an unwarranted technical risk in doing anything else.

    However, for the next generation it is open season of course.

    Jewel in the Crown at Risk. But the real worry must be the Public Regulated Service (PRS). This is the unique feature of Galileo that is of great interest to civil and military authorities in Europe and beyond, due to its more robust encrypted signal and its potential anti-jamming and spoofing characteristics. Currently PRS will only available to EU Member States. In fact access to a PRS workshop at the European Space Solutions event (see below) was strictly “EU citizens only.” However, other countries, including the US and Norway, have indicated that they would love to be able to use it as well. No final decision on this has yet been made.

    The loss of the automatic right to access PRS would be damaging to the UK, and potentially to the full Galileo deployment timetable, as the country is currently host to the back-up Galileo Security Monitoring Centre (GSMC) — an essential part of PRS infrastructure — and I cannot see any part of the PRS infrastructure being left in a non EU Member State. PRS has been described as the “jewel in the Galileo crown,” but if the centre must be relocated then deployment of the full service could be delayed.

    In addition, the UK involvement in research and innovation activities around PRS may well be curtailed, even if other work on Galileo projects is not.

    The UK has been a leader in developing PRS applications. For example, Mark Dumville and colleagues at Nottingham Scientific Limited (NSL) have recently provided some very impressive demonstrations of cloud-based PRS applications including the first demonstration of the implementation of PRS authentication for an offender tag that was demonstrated using live Galileo (and GPS) signals. The demonstration provided real-time authentication flag generation, release and delivery to users. A second demonstration used cloud-based PRS in a proof-of-concept remote unattended, timing station where the primary user requirement was 100% confidence for the validity of signal. And a third demonstration illustrated the use of cloud-based PRS on a drone. “For users, demonstration of accreditation is key,” said Dumville when describing these results at the European Space Solutions event.

    Personally as a British citizen, and one who has spent the last 15 years in and out of the Brussels bubble, I see the EU referendum result as a national tragedy of epic proportions; and one that has been a long time in the making. Many global commentators are saying the UK has shot itself in the foot; sadly, in my opinion, it is much, much worse than that.

    United Europe

    The referendum news has certainly put a dampener on what I was hoping to be an optimistic, forward-looking article following the European Space Solution event in The Hague at the end of May. This was the fourth European Space Solutions conference and exhibition, attracting a large, global audience of policy-makers and industry players.

    At a press briefing just before the event kicked off on 30 May, and after an informal EU competitiveness ministerial council, Dutch minister for Economic Affairs Henk Kamp spoke about the ideas behind the forthcoming EU Space Policy. The policy, which should appear in the autumn/ fall, aims to elaborate a single and coherent European space strategy that will be the foundation of space programmes up to 2030.

    The policy will look to achieve three clear objectives:

    • to develop a strategy to ensure Europe maintains a strong and globally competitive space sector both upstream and in terms of use of data from space;
    • ensure independent access for Europe to space;
    • and maintain and upgrade the existing European space infrastructure — namely Galileo and Copernicus.

    Growth Vectors. Elżbieta Bieńkowska, the European Commissioner with responsibility for EU space programmes, indicated that the space policy would provide a “Coherent space vision for decades to come” and would be subject to public consultation. She was looking for “Maximum return on current programmes … and to respond to emerging needs in areas such as climate and security sectors.” The strategy will consider space-enabled solutions to societal challenges and as vectors for growth.

    She mentioned more than once that she is looking for long-term sustainability for the sector: a space sector that is able to adapt to disruptive technologies and maintain its competitive edge. My interpretation of this is that public money (from Europe) may not be as plentiful as previously, and the Commission will be looking for greater leverage of its tax Euros — that is, the private sector will need to invest more.

    Lowri Evans, Director-General for Internal Market, Industry, Entrepreneurship and SMEs, at the European Commission took up this theme. She saw huge opportunities as the cost of entry to the sector diminished, however private investment was still a problem. There was not enough in the EU and this must change. The Commission is aiming to create an environment for successful investment, she claimed.

    Jan Worner, the very positive Director-General of ESA said that “Space was indispensable” as an instrument for economic growth. It was also fascinating and inspiring. He felt it was also important that the different players in the EU space scene are working together for a “United Space in Europe.”

    The conference was also the venue for the official signing of the agreement for the future Galileo Reference Centre (GRC) that is to be established at Noordwijk in The Netherlands. The centre will play a crucial role in independently monitoring and reporting on Galileo’s performance and the quality of the system’s signal in space.

    Dual-Use Debate

    PRS was also a major talking point at the European Space Solution’s panel on ‘Space and Security.’ Despite the fact that Galileo is marketed as a civil controlled GNSS, “dual use” is becoming a potentially divisive area for debate. Marian-Jean Marinescu, MEP said there was a need for a common European defence and security strategy that includes securing all elements of the space value chain.

    Rini Goos from the European Defence Agency (EDA) said that the EU needed space systems to be able to “intervene successfully” and that space strategy needed to support Member State defence capabilities. This meant that the next generation of EU space systems must have dual-use capability. NATO is entrusted with external defence of the EU, but the Commission also needs to be able to provide defence, not just consume it, he concluded.

    Current Chairman of the Galileo Security Accreditation Board is a UK citizen – Jeremy Blyth. He said: “Space and Security, Security and Space. Whichever way we say it what is clear is that the two are inextricably linked together.” He believes that to ensure security it must be there “designed in from the beginning.” Security is an enabler, rather than a barrier, he claimed.

    He also believes that PRS gives the EU a real and competitive edge in secure positioning. However he indicated that there is a need to think deeply and have a rational debate about dual-use systems and in particular about the interface between civil and military use.

    Clearly there is a growing tension with regard to overtly military use of Galileo both now and in future generations of the system. Although a largely philosophical debate, given who in reality will be controlling and using PRS within many Member States, many European and national policy makers will want to retain the “purity” of Galileo as a global positioning system under fully civilian control.

    PRS Workshop

    Security was also a key feature of the PRS workshop organised by the Netherlands EU Presidency towards the end of European Space Solutions. Ger Nieuwpoort, Director of the Netherlands Space Office (NSO) reminded the audience that “For civil authorities, PRS provides the same level of security for Member States as the military in GPS.” While Christoph Kautz from the Commission said that the “Rationale for PRS was threats and user needs: better availability, high continuity, authentication, access control, exclusivity.”

    PRS offers defence in depth with a robust signal in space providing higher protection plus strong encryption on ranging codes, and the navigation and service messages. And the access to the technology is highly restricted.

    However some issues still need to be resolved. Bart Banning of the Netherlands Institute of Navigation asked ‘How will we use PRS?’ In terms of its use for protecting critical infrastructure, what if the owner of the infrastructure was a private company? Should it be granted access to PRS or have to make do with the Galileo Commercial Service aka PRS-lite?

    He also pointed out that PRS was no more protected against jamming than any other GNSS. And, currently, it was “not good for in-building, underground, or underwater.”

    He thought PRS could be a great time provider, but probably also need ground transmission, possibly via legacy radio towers. However, he saw the “killer app” for PRS being asset tracking of, for example, diamonds, VIPs or prisoners. He also agreed that for many EU countries the ministry of defence will be overseeing PRS services. “PRS is a good and unique addition to GNSS — but not the answer to all our needs.”

    Banning also highlighted the issue of commercial companies looking to buy LORAN / e-LORAN sites in Europe to provide a commercial service to back up GNSS. After the recent GPS timing glitch he said that the “timing community” had woken up to the vulnerability of their operations.

    Geospatial

    On a different tack, from 23–26 May the eighth edition of the Geospatial World Forum [www.geospatialworldforum.org] took place in Rotterdam, attracting professionals from the surveying and geoinformatic systems (GIS) sectors. I attended the event on 24 May and took part in a workshop that looked at the benefits of Galileo and EGNOS in geospatial applications in the context of the imminent launch of Galileo initial services.

    An industry survey undertaken by the GSA indicates that already more than 80% of GNSS receivers for surveying and mapping use are EGNOS-enabled, while 77% of geospatial reference network providers have enough information to upgrade Galileo and will be ready to provide a service by 2017. All good news. On the less positive side, more than 60% of professional surveyors did not know about EGNOS!

    The workshop also talked up the potential for synergies between Galileo GNSS and Copernicus Earth Observation (EO) systems — a topic of immense interest at the European Space Solutions as well. Hans Dufourmont from the European Environment Agency (EEA) highlighted the use of GNSS to track animal species and monitor migration paths when considering development opportunities. He saw a huge potential for synergies between geopositioning and surface imaging going forward.

    Maurice Barbieri, President of the Council of European Geodetic Surveyors (CLGE) also saw a “clear role for Galileo” in the surveying community with its potential ability to meet centimetre accuracy requirements much more than for EGNOS. He also speculated about the value of establishing a European Geoinformatic Agency that might coordinate the provision of European GNSS and EO data. He felt the private business community would appreciate such simplification.

    One presentation that caught my eye was from Laura van de Vyvere of M3 Systems in Belgium. She won the first-ever European Young Surveyor Prize with a paper taken from her Master’s thesis. The presentation addressed an innovative use of Galileo’s unique signal in space that is carried on four frequencies in the Open Service. Her work showed that the four frequencies enabled more precise phase measurements than with GPS so cycle slip is easier to detect and positioning data and reliability can be improved especially in harsh ionospheric conditions. The algorithm she developed could enable affordable multi-frequency receivers for mass-market applications, she claimed. An interesting idea.

    A bientôt, as they say in these parts.

    Meeting on Thursday, June 23, at its headquarters in Prague, the Administrative Board of the European Global Navigation Satellite Systems Agency (GSA) elected its new chair: Jean-Yves Le Gall, Centre National d’Etudes Spatiales (CNES, the French space agency) president and France’s interministerial coordinator for European satellite navigation programmes.

    Le Gall succeeds Sabine Dannelke, German federal minister of Transport and Digital Infrastructures.

    Headquartered in Prague, GSA is in charge of managing operations of satellite navigation systems on behalf of the European Union since 2014 for the European Geostationary Navigation Overlay Service (EGNOS) and from 2017 for Galileo. Carlo des Dorides is GSA’s executive director.

    Commenting on his election, Jean-Yves Le Gall said: “I am most honoured to have been elected Chair today of the GSA Administrative Board, with Galileo now poised to enter its operational phase.

    “My election recognizes France’s key role in satellite navigation, reflected in the commitment of the members of the Interministerial Working Group (GTI) and CNES’s historic expertise in this domain, for which it has shown unwavering support for the EGNOS and Galileo programmes since their inception.

    “This election and that as Deputy Chair of Mark Bacon, representing the United Kingdom, also confirms EU member states’ desire to join forces through Europe’s Space Team on the cusp of a period that is set to prove most prolific for GSA, since it will be moving Galileo towards full operational capability.

    “I would like to thank Sabine Dannelke for her decisive action over the last few years as Chair of the Board, and I very much look forward to working hand in hand with Executive Director Carlo des Dorides and everyone at GSA, whom I know, like and respect.”

  • Demonstration tests positioning in the far north

    Demonstration tests positioning in the far north

    News from the European Space Agency

    A sea-based test is demonstrating the potential of extending satnav augmentation coverage into north polar regions, offering a safety-of-life standard of navigation performance to users including shipping or aircraft in flight.

    Norwegian research vessel Gunnerus, owned by the Norwegian University of Science and Technology, is equipped to pick up satnav signals from GPS and GLONASS as well as augmentation signals specially generated for the test, modeled on Europe’s existing European Geostationary Navigation Overlay System (EGNOS).

    Gunnerus is making use of the signals during five days of sailing off Trondheim. The demonstration is part of the Arctic Test Bed project, conducted within the European Global Navigations Satellite System Evolutions Programme (EGEP) of ESA.

    The ESA-designed EGNOS improves the precision of US GPS signals over most European territory, while also providing continuous and reliable updates on their integrity.

    A 40-strong network of ground monitoring stations perform an independent measurement of GPS signals, so that corrections can be calculated and then passed to users immediately via a trio of geostationary satellites. The result is a several-fold increase in precision.

    “Simply due to Earth’s curvature, EGNOS signals are not visible above about 70 degrees north, but they are needed to support polar routing,” explains Marco Porretta, overseeing the Arctic Test Bed project.

    To investigate possible methods for improving Satellite-Based Augmentation System (SBAS) performance in this Arctic region, the test campaign will assess the benefits of augmentation for various types of satnav signals: single-frequency GPS; dual-frequency GPS; and dual-constellation dual-frequency, where GPS signals are combined with those of its Russian counterpart, thus increasing the number of observations.

    “The planned next-decade upgrade of EGNOS, along with other augmentation systems operated over other continents (such as the U.S. equivalent Wide Area Augmentation System, WAAS), will perform multi-constellation augmentation as standard,” adds Marco. “That means data from this test case should be especially valuable to support interoperability between future augmentation systems.”

    The Arctic Test Bed makes use of some EGNOS reference stations along the north of Europe, along with additional stations in locations including Greenland, Jan Mayen Island, Spitsbergen and Norway.

    Marco explains, “These stations will allow specific monitoring of the ionosphere — the electrically active segment of Earth’s atmosphere — in the Arctic region. The ionosphere is significant because it is an important source of satnav signal delay, or in some cases can cause receivers to lose signal lock due to ionospheric scintillations.”

    With geostationary satellites out of sight, navigation corrections for the Arctic Test Bed will be transmitted via terrestrial radio. In future, an operational version of the system could either stick with this solution or rely on other satellite-based means of dissemination from non-geostationary orbit.

    The all-important generation of the augmentation correction message will take place at a processing center in Hønefoss, Norway, using adapted EGNOS algorithms.

    An operational version of the Arctic Test Bed could potentially extend augmentation coverage to as high as 85 degrees north, as high as Greenland, extending to the edge of WAAS coverage.

    The Arctic Test Bed project was initiated by ESA, with Kongsberg Seatex serving as prime contractor, GMV Aerospace and Defence, Thales Alenia Space France, Logica, Terma, the Norwegian Mapping Authority, Technical University of Denmark, Septentrio and the University of Calgary.

  • User location data could support satellite launches

    User location data could support satellite launches

    Let’s look through the other end of the telescope this month. The satellites are nattering along, lining up in orderly fashion at the rocket pad, extending their solar arms smoothly in space once they arrive on orbit. The constellations accrue and new signals inch closer to maturity.

    The only blips on the horizon come from Ligado’s terrestrial impulse and a looming gap in GPS ground control. Just possibly, the latter might coincide with activation of the full European constellation and Galileo could come to the rescue of suitably equipped users who hunger for greater accuracy. This has been Galileo’s raison d’etre for two decades now, and it may actually be on the cusp of coming true.

    At any rate, back to the telescope’s other end. What might that be? Facebook.

    FB_Location-W“When you think back to the beginning of online advertising, this is what advertisers have been waiting for.” That is Facebook’s director of monetization product marketing — an actual job title, and a powerful one in time to come.

    All this — what advertisers have been waiting for — is made possible by GPS. Soon, by all GNSS. And by your smartphone.

    From a GNSS Design & Test point of view, this means we are about to see some real money come available for constellations. Fast-multiplying applications of position, navigation and timing data have always shaped GNSS evolution, to some degree. Making this latest development different by a degree of magnitude is its potential to alter the way GNSS policy is shaped and the way GNSS funding is provided.

    Facebook will soon roll out a new Store Visits metric for business clients: location data and purchases correlated to Facebook ad performance. Partnerships with point-of-sale systems like Square and Marketo will “prove” (let’s use that word loosely for now) who bought what after seeing Facebook ads.

    The way the company tells it, “While people use mobile in 45 percent of all shopping journeys, more than 90% of sales still happen in brick-and-mortar businesses.”

    Even if you don’t buy something, Facebook will know that you — assuming, and this is a big jump, that you are a Facebook user — visited a store by aligning GPS, beacon, Wi-Fi and other radio-frequency signals and cell-tower locations with brick-and-mortar coordinates. You may not be a Facebook user, but I’ll bet one of your loved ones is.

    With the new feature, instead of having to (gasp!) leave Facebook to visit an unfamiliar website for a store locator, users can view the address, hours, phone number and estimated travel time without exiting the social network.

    Cleveland_on_Facebook

    I know people who rarely or never leave Facebook. Do you? This is a plus for them.

    Facebook, one of the new corporate mega-giants, duels with Google, Apple and Microsoft over various pieces of digital turf. One of the most hotly contested treasures — the Holy Grail, in marketing execs’ terms — is the capture and use of user data. It is getting more than a little bit creepy.

    To date, the even-bigger giant that is advertising has used metrics such as ad views and clicks to measure effectiveness: how much an ad actually inspires purchase or response to other calls to action. I know this because I use these metrics, or someone in my organization does. Such metrics are now deemed “flimsy” by the standards of aligning GPS, beacon, Wi-Fi data and so on as outlined above.

    Facebook is not alone in exploring the fertile ground. Google recently launched ads that show maps of nearby locations, and the others surely do not lag far behind. For the moment, these massive integrators aggregate and anonymize the data to protect privacy, but that’s not to guarantee they would always do so. Currently, there’s no specific opt-out other than turning off location services for the app on the user’s device, which people might be reluctant to do if it degrades other app functionality.

    Let’s shield our eyes from the dark side for the moment, and consider what this means for GNSS.

    We, you and I, those of us in the PNT industry, have known for some time how integral to critical infrastructure GPS is and GNSS soon will be. But the vast public does not. And lawmakers, bless their little hearts, largely do not either. That will change when the desperate craving of large companies to reach billions of buyers enters the PNT arena.

    We can envision mega-marketing bolstered by alliance with the transportation industry, both ground and air, as driverless vehicles and drones become more commonplace. With powerful lobbying interests behind it, GPS might finally get some respect, and other systems around the world with it. Modernization might proceed more smoothly and quickly, without funding hiccups and capability gaps. That’s the bright side of all this.

    It reminds me of nothing so much as an old rock’n’roll song. In “Top of the Pops,” the Kinks sang:

    Now my agent called me on the telephone
    He said, son your record’s just got to number 1
    And you know what this means?

    This means you can earn some real money.

    Following rigorous testing in France and Germany, a new type of dispenser designed to carry four navigation satellites into orbit at once is now in French Guiana, in place for Galileo’s first Ariane 5 launch later this year.

    The dispenser is an essential element of launch success, with a double role to play. It first must hold the quartet of satellites securely in place during the stresses of liftoff, and then the nearly four-hour long flight to medium-Earth orbit.

    Then, once the Ariane 5 EPS upper stage reaches its target altitude of 23,222 kilometers , the dispenser will release the four Galileo satellites using a pyrotechnic release system triggered by separate igniters, each one firing half a second after the other.

    The separated satellites are then pushed away from the dispenser in separate directions using a spring-based distancing system.

    The 447-kilogram dispenser, designed by Airbus Defence and Space, must support a satellite mass of 738 kilograms each – nearly three tons total.

    Made from a combination of metal and composite materials for maximum stiffness, the dispenser has undergone very comprehensive testing at Airbus Defence and Space near Bordeaux, France, and the IABG testing centre in Ottobrunn, Germany – using both Galileo engineering models and an actual flight satellite, including fit, shock and separation testing.

    The test campaign met all objectives, reports the ESA, confirming the behavior performs as predicted, after which the dispenser was shipped to Europe’s Spaceport in French Guiana.

    This fall, four Galileo satellites will be launched together for the very first time on a specially customized launcher — the Ariane 5 ES Galileo.

    In development since 2012, the new launcher variant has evolved from the Ariane 5 ES (Evolution Storable), used to place ESA’s 20,000-kilogram ATV supply vehicle into low-Earth orbit.

    This launder has to carry a lower mass payload – four fully fuelled 738-kilogram Galileo satellites plus their supporting dispenser – but needs to take it up to the much higher altitude of medium-Earth orbit, approximately 23,222 kilometers up.

    The target orbit is actually 300 kilometers below the Galileo constellation’s final working altitude, which leaves the Ariane’s EPS upper stage in a stable “graveyard orbit,” while the quartet of Galileos maneuver themselves up to their final set height.

    Once the Ariane 5 ES Galileo flight is complete, there should be 18 Galileo satellites in orbit.

  • Prince’s death highlights 911 location issues

    Prince-signPrince’s death on April 21 highlights a fatal flaw in the United States’ antiquated 911 emergency system. When you call from cell phone, 911 doesn’t automatically know where you are. 911 often can’t determine the location of an emergency, even when the call for help comes from a GPS-equipped smartphone. Often the 911 operator can only zero in the nearest cell tower, which can be several miles away or in the next county.

    In the transcript of the 911 call from Prince’s house comes this exchange:

    911 operator: OK, what’s the address?

    Caller: We’re at Prince’s house.

    911 operator: OK, does anybody know the address? OK, your cell phone’s not going to tell me where you’re at, so I need you to find me an address … OK, have you found an address yet?

    Caller: Yeah, um, I’m so sorry, I’m so sorry. (The caller is heard asking others if they know the address.)

    911 operator: Is there any mail around that you could look at?

    While a quicker response may not have saved Prince’s life, some experts estimate that cutting 911 response by one minute could save one person every hour every day nationwide.

    The FCC and the four largest cellphone carriers say they’re doing their best to address the problem. One possible solution is LaaSer, a technology suite that runs in the cloud. LaaSer updates your precise location at the exact same time that the call to 911 is being made, so that the answering operator is immediately presented with your information.

    With Laaser, any mobile device delivers accurate location information about the caller to 911 operators immediately. It does this using existing infrastructure, so carriers, handset manufacturers and 911 call centers wouldn’t have to change their systems to receive the benefits.

    Unlike current 911 mobile phone technology, LaaSer takes advantage of all of the location information already available in smartphones, including GPS, Wi-Fi, Bluetooth, near-field communications (NFC)/RFID, compass, accelerometer, barometer and more.

    Our lives may depend on it.
