U-blox, a global provider of positioning and wireless communication technologies, is partnering with Arvento Mobile Systems, a Turkey-based fleet telematics company, to develop a compact people and asset tracking device with a long battery life.
The Arvento Treyki Mini has eight operating modes, including special settings for tracking children (with geofencing) and senior citizens (with an integrated fall sensor). It is also suitable for use in sports, racing and asset management. It can also be used as an emergency beacon.
The tracker has an onboard positioning receiver, and reports its location using an internal GSM/GRPS modem. It can operate for up to seven days from its 900mAh LiPo rechargeable battery before it needs to be recharged.

The Treyki Mini relies on the u-blox ZOE-M8Q concurrent multi-GNSS module to discover its location. This system-in-package (SiP) offering is 4.5 x 4.5 x 1.0 millimeters. It provides high accuracy thanks to its ability to receive 72 channels simultaneously, from up to three different GNSS constellations, the company said.
It also offers reliable positioning in challenging environments because it has a sensitivity of –167 dBm and is energy efficient.
Communications for the Treyki Mini are provided by the u-blox SARA-G340 dual-band GSM/GPRS module — its very low standby power of less than 0.90 mA helps extend the Mini’s battery life. The SARA-G340 module also supports firmware-over-the-air (FOTA) updates, enabling Arvento to continue to refine the Treyki Mini after production.
“The Treyki Mini is the result of a very close collaboration between Arvento and u-blox to optimize its size and power consumption,” said Özer Hıncal, general manager, Arvento. “We expect that the strong sense of partnership that evolved between our two companies during the development of the Treyki Mini will lead to further collaboration in the future, especially when it comes to telematics system solutions.”

The Septentrio team — including Andrew Simsky, navigation algorithms software engineer; Wim De Wilde, system designer; Jean-Marie Sleewaegen, system architect; and Tom Willems, senior researcher — received the 2018 GPS World Products Leadership Award for developing the versatile PolaRx5 receivers, enabling many Earth-observing applications including worldwide ionosphere monitoring. Sleewaegen offers the team’s acceptance speech below.
It is a great honor and privilege to be here and we are very happy to receive this wonderful award. On behalf of my colleagues Tom, Andrew and Wim, and the entire Septentrio team in Belgium, I would like to thank Alan and all sponsors and organizers of this dinner.
From the beginning, Septentrio enjoyed close ties with the scientific community, and we continue to cherish this connection. Our PolaRx receivers, and especially our ionosphere monitoring receiver, is the result of a close collaboration with scientists at universities and research institutes around the world, some of them present here. While the GNSS industry was and is still largely relying on legacy L1 signals, they have been early adopters of all new signals and constellations. For us, this has been a great motivation to implement support for all signals and frequencies at the earliest stage of availability.
Ionosphere scientists are special folks. While most of us dream of getting rid of error sources, they just focus on them, and more specifically on small delays and variations caused by the atmosphere. They don’t want us to filter out these perturbations. On the contrary, they want to see them in their full glory. But the problem is, there are plenty of other error sources. Multipath, clock jitter, vibrations, hardware biases, interference are all out there and are hard to distinguish from what the ionosphere is doing. Our challenge was to minimize those noises and biases to extract the underlying physical signals. This exercise was really instructive, and this technology which we developed for the scientific community is now in the heart of all our receivers.
Looking ahead, while the avalanche of new signals and satellites is an opportunity, it is also a huge challenge. In some regions, we can already track more than 60 GNSS satellites, all transmitting multiple signals, and this number will only keep growing.
How to use all this information? What is the optimal set of signals for a certain application? Are these signals all useful? With the many tracking options, how to guarantee compatibility between vendors? Many open questions still remain to be answered and will keep us busy for the years to come.
We really appreciate the opportunity to be here, thank you for listening!

John Raquet’s team has developed PNT sensors and systems utilizing GPS, GNSS, inertial, vision, lidar, magnetic field, pseudolites, radar, terrain mapping, signals of opportunity, star trackers, radio ranging, 3D audio, X-ray pulsars, clocks, and more. Raquet, director of the Autonomy and Navigation Technology (ANT) Center at the U.S. Air Force Institute of Technology, received the 2018 GPS WorldServices Leadership Award for his achievements. Check out his acceptance speech below.
I feel like I have the best job in the world, because I get to try to implement many new ideas and work with amazing people as I do so. We have developed and tested lots of new ideas, to the point that I sometimes call the ANT Center the “crazy idea factory” — we love to turn crazy ideas into really good ideas that will make a difference.
But there’s another part of my job that I feel especially proud of: the students we produce. Ours is not the kind of community where you build something once and then the job is done. Rather, this is a growing worldwide enterprise that takes new talent to come in and eventually fill the spots that many of the people in this room have occupied.
I’m privileged in my role as a professor to be able to fill some of those gaps, and it’s rewarding to see students that we’ve worked with go on and do some really amazing things, and to know that we had a small part in helping them to do that.
I’m grateful to GPS World, to the sponsors, and to my ANT Center colleagues. It’s a great honor to receive this award — thank you very much.

Logan Scott, principal at LS Consulting, is the inventor of an asymmetric navigation security paradigm for civil GPS signals that avoids the need for secure key storage in civil receivers and allows for widespread adoption in applications without physical security capabilities. Scott received the 2018 Signals Leadership Award from GPS World magazine. Read his acceptance speech below.
A crucial first step in developing resilient responses is to recognize that there is a problem so you can isolate it. Otherwise, an overly trusted element can contaminate the solution.
I am honored to accept this award from GPS World and our sponsors tonight. It has been a long journey from my initial vision of how civil signals might be authenticated to where we are now, with a draft Chimera signal specification nearing readiness for review.
I’d like to thank the Air Force Research Laboratory for sponsoring these efforts, and I would also like to acknowledge the outstanding efforts of the entire signals working group without whom this milestone would not have been reached: Captain Katie Carroll, Jon Anderson, Joanna Hinks and Nate DeVilbiss who brought me in on the project; Joe Rushanan and Jim Gillis who taught me so much about cryptography; Renee Yazdi and Brady O’Hanlon who pushed for no compromises. Working with this team has been one of the highlights of my professional career.
We have a solid design that fully realizes the benefits of chip-level binding with both fast and slow authentication capabilities. Chimera can offer security benefits far beyond the security theater of data message signing only. Moreover, it is a first step towards proving location.
Moving forward, the challenge I offer to you all is this: how can we establish the integrity and truthfulness of position and time reports both locally and remotely? How can we prove location, not only to ourselves but also to remotely located entities? In a world of autonomous vehicles, geofenced capabilities and information access, and an insecure supply chain, it is not enough to say that “I saw it on the C/A code.”
Complementary and overlapping techniques are essential in establishing the veracity of any claims. In support of this, we can and must provide assured spectrum protections for all GNSS systems.

Javier Benedicto, head of the Galileo Programme and Navigation-related Activities at the European Space Agency, accepted the 2018 Satellites Leadership Award and delivered these remarks on behalf of Giuliano Gatti at the 2018 GPS World Leadership Awards Ceremony. Gatti, the space segment procurement manager at the European Space Agency, received the award for his contribution to setting up the Galileo constellation from GIOVE-A and -B precursors through all Galileo operational satellites: Soyuz and Ariane 5 launches, a total of 26 Galileo satellites deployed in 7 years.
On behalf of Giuliano Gatti, I express his gratitude for this award.
After a 20-year career in microwave equipment for satellite application, working in Italy, Canada and the Netherlands, Mr. Gatti started working on navigation satellites at end of the 1990s as ESA Galileo Space Segment Manager.
He went through the initial difficulties of the program, namely the uncertainty on financing and the technical lack of maturity of critical units such as atomic clocks. At the time, joining the Galileo team of the European Space Agency was risky and challenging.
In spite of these issues, he was a key player in the developments of the first two Galileo experimental satellites, GIOVE-A and GIOVE-B, and he was in charge of their launches in 2005 and 2008, respectively, on Soyuz rockets from Baikonour, Kazakhstan.
He then followed the development and launch of the 4 IOV satellites, two in 2011 and two in 2012, from the European space port in French Guyana, on a Europeanized version of the Soyuz rockets. The first IOV launch was actually the first launch with this version of the launcher, and interface and schedule coordination issues were challenging tasks for him.
He then was instrumental for the procurement of the following generation of satellites, the 22 FOC satellites. He struggled to make sure that satellites would be produced and launched in line with the program deployment plan. Another challenge in this phase was ensuring that the adaptation of the Ariane-5 ES rocket to the Galileo satellites would converge in time and comply with all technical requirements.
Under his guidance and responsibility, the 22 satellites were put in orbit with 5 Soyuz launches and 3 Ariane-5 launches. Here the most difficult event was the launch that put two Galileo satellites in the wrong orbit, and the subsequent recovery of the satellite mission. In addition, a number of failures affected some of the in-orbit atomic clocks, and hedrove the investigation that led to the discovery of the root causes and their resolution.
Mr. Gatti then initiated the procurement and production of the follow-up recurring satellites, the so-called Batch-3 satellites. These 12 satellites have stringent schedule requirements and their first launch is planned for late 2020 or early 2021.
In parallel, he contributed to the definition of the next generation of satellites, the Transition Satellites: heavier spacecraft with improved performance and high level of re-configurability and flexibility. They will be the first step moving from the existing first generation of satellites to the second generation. In this phase, his experience and competence have played a fundamental role to arrive at the definition of the appropriate procurement requirements.
After 20 years on the development and deployment of Galileo, being in charge of the launches of 28 satellites, from the first GIOVE-A satellite in 2005 to the launch of the last 4 FOC satellites in July 2018, Mr Gatti will retire in mid-2019.
He is delighted and honored that all his efforts and contributions to develop and launch the Galileo constellation have been recognized in this important GNSS event.
The 2018 GPS World Leadership Awards, presented in September, recognized significant recent achievement in Satellites, Signals, Services and Products. The Awards Dinner and Ceremony was sponsored by Harris Corporation, Rockwell Collins and Spirent Federal Systems.

Words from our sponsors
Satellites. “We have seen our military and professional users looking to greater flexibility in their use of GNSS, as new capabilities and constellations come on line. But with that flexibility, a retention of assurance and where possible, mitigation of threats. For this reason Rockwell Collins and QinetiQ signed an agreement to produce a new family of high-assurance, multi-constellation GNSS receivers for professional and military use.
“This new family of receivers, complementary to the current encrypted family of Rockwell Collins receivers in service across the globe, allows the customer to select level of capability and protection based upon their operational, political or even financial needs. The new MICRO family of GNSS receivers will offer a multi-constellation open service (MCOS) GNSS capability, which will initially provide two receivers; the Q40-MicroPNT will address dismounted low-dynamics requirements, and the Q40-MicroSTRIKE will be a gun-hard, high-dynamics receiver.” —Phil Froom, Rockwell Collins
Signals. “For over thirty years, we’ve overcome challenges and delivered GPS payloads that provide a technology the world uses every day. We’ve gotten to the point where we can honestly say, almost nothing works without GPS. The challenge that I see [for the future] is to overcome the politics: Where do governments of GNSS draw the line between doing what’s right for a PNT solution for the common good of humanity globally versus addressing your national security and protecting your own country? Truth is, because of politics, year after year our government has been forced to start the fiscal year with a continuing resolution because our politicians can’t approve a budget.” —Joe Rolli, Harris Corporation
Services. “We’ve been manufacturing GPS simulators for the past 30 years. This year we launch a new product, SimMNSA. We’re currently in the final test phase of this new M-code option and we’ll be delivering to several authorized customers by the end of the year. We also offer products that simulate all other GNSS signals, plus a variety of other sensors.” —Ellen Hall, Spirent Federal
Mobile Recon Systems is offering an unmanned aerial vehicle that can lift more than its own weight.
At 78 pounds, the Dauntless multi-rotor UAV has lifted an additional payload of 100 pounds as a tethered quadcopter, the company said. It is designed to lift more than 200 pounds as an octocopter, with a generator-powered flight time of several hours.

“Drones have proven to be great for videography. But uses beyond that have been limited by low lift capacity, limited flight time and narrow functional capability,” said Mobile Recon Systems founder Mike Dowell. “With the Dauntless, that is no longer the case.”
Not only can the Dauntless carry up to 160 pounds of supplies in a climate-controlled transport box, it is a multi-functional platform. It can be outfitted with sensors, radiation detectors, radar, weather stations, multi-spectral, thermal and infrared cameras, and other devices. It can perform eight or more different functions at once. Plus, users can easily swap or combine devices to meet their needs.
Those capabilities enable this model to deliver high value services previously out of reach for UAVs, the company said.
“The Dauntless is ideal for border and perimeter security, as well as natural disaster response, medical emergency first response, routine inspections and aerial analysis, and mapping,” Dowell said. “With its lift capacity, it can carry high-end lidar and cameras, as well as supplies. Our flexible platform offers a myriad of possibilities.”
To illustrate, the Dauntless can carry an MSOP and four multi-axis gimbals, mounted on top and bottom, to accommodate optical, thermal and multispectral cameras, including a RED Epic. high-end digital camera. These can simultaneously capture multiple types of images from below, front, overhead, right and left of the flying platform.
The Dauntless has a full 3K (military-grade) carbon-fiber body and titanium and aircraft aluminum frame. The propellers are carbon fiber, and are safely surrounded by the body. It is waterproof and sandproof.
Version 20 of the Global Mapper Software Development Kit (SDK) is now available, along with the accompanying Lidar Module SDK. Mirroring the most important capabilities of the desktop version of the software, the powerful developer’s toolkit provides software engineers with the means to embed the latest geospatial technology into their custom applications, according to software maker Blue Marble Geographics.

Among the highlights of the version 20 release are dramatically improved vector data performance in both the 2D and 3D environments, updated 3D mesh rendering with colors now displayed in the 2D view, and faster display and export of online tiled datasets, the company said.
For more than 25 years, Blue Marble’s affordable, user-friendly GIS software has been meeting the needs of users in industries including software, oil and gas, mining, civil engineering, surveying and technology companies, as well as government departments and academic institutions.
The Global Mapper GIS application can display, convert and analyze virtually any type of geospatial data. The Global Mapper SDK and Lidar Module SDK provide software developers with a toolkit for accessing much of this functionality from within an existing or custom-built application.
The SDK also enables the creation of custom toolbars and extensions to enhance the data processing and analysis functionality of the standard version of Global Mapper. This capability allows in-house developers to create a unique version of the application to meet their specific needs or for software companies to build custom products for commercial distribution.
The functional highlights of the latest version of the SDK effectively illustrate the continued evolution of 3D GIS technology and Blue Marble’s commitment to providing a superior data processing engine for managing, visualizing and analyzing increasingly large 3D datasets. Such is the case with the improvements that have been made to the display performance of vector files with faster rendering in both 2D and 3D Views.
The display of 3D meshes or models, such as those created in Global Mapper’s Pixels-to-Points tool, has been improved with the photo-realistic colors now displayed in the top-down view. Online data processing has also seen improvements with significant speed increases when loading and exporting tiled data sources.
Additional upgrades to the SDK functionality include improved box resampling of color images, especially those with palettes; several new supported formats, including Cyclone PTX and Autodesk Recap (RCP and RCS) point clouds; new projections and datums, including GDA2020 (Australia) and TUREF (Turkey); and support for Intermap’s online NextMap worldwide elevation dataset.
For users of the Global Mapper Lidar Module, the version 20 SDK release also introduces a wealth of new and updated functionality. Point clouds can now be thinned, from both a 2D and 3D perspective, reducing file size and improving efficiency; a gridded layer can now be created from the classification values associated with lidar points; and a new scripting option has been added to apply colors to a point cloud from underlying imagery.
“The Global Mapper SDK has become one of the most important components of Blue Marble’s suite of geospatial products,” stated Patrick Cunningham, Blue Marble President. “Motivated by the rapid emergence of the desktop software as a major player in the GIS industry, developers are increasingly turning to the corresponding SDK to leverage the software’s powerful geoprocessing tools in a wide variety of third party applications. The improved data handling capability of the version 20 release demonstrates our commitment to providing tools that work efficiently with even the largest datasets.”
Two tiny GNSS-RO nanosatellites now circle the Earth, ready for action. The first European Pioneer mission lifted off Nov. 29 from Sriharikota, India, to put the satellites into orbit.

The shoebox-sized satellites were launched at 04:27 GMT into low Earth orbit by the Indian Space Research Organisation’s PLSV launcher, and opened their first communication windows with their owner, Spire Global, less than an hour after they separated from the rocket.
Both satellites were developed under ESA’s ARTES Pioneer programme, and will aim to prove the value of using nanosats for space-based GNSS Radio Occultation (GNSS-RO).
GNSS-RO. GNSS-RO is the process of using satellites to measure how GNSS signals are refracted by the Earth’s atmosphere. Experts can use these measurements to glean temperature, pressure and humidity information for weather forecasting and climate change monitoring.
In contrast, weather data gathered by weather balloons and aircraft can only reach certain altitudes, leaving the higher atmospheric layers untouched.
Satellites have no such restrictions. They can gather massive amounts of this data from the ground up to the mesosphere as they fly over the Earth. This is usually done by large satellites. Spire’s nanosatellites weigh just 5 kg each, and were assembled and tested entirely by Spire in under three months, at their headquarters in Glasgow, Scotland.
Named “Space as a Service,” the Spire Pioneer mission intends to prove that nanosat GNSS-RO is a commercially viable alternative to traditional methods.

The two tiny satellites will collect and distribute GNSS-RO data during their commissioning phase, after which they will go into full commercial data production mode, gathering weather information for meteorological institutions, maritime and aviation customers on demand.
ESA’s Pioneer initiative partners with companies like Spire to help them provide this kind of in-orbit demonstration and validation for third parties.
“We saw a gap in the market for what we call space mission providers: companies that offer all aspects of a space mission to validate a new technology or service for the benefit of others,” said ESA Pioneer Programme Manager Khalil Kably. “ESA is always looking to champion innovation in the space industry, and the idea of Pioneer is that these space mission providers can help this by being a one-stop shop for in-orbit demonstration and therefore reduce the barriers and complexity that can stifle new ideas.”
“Spire has been focused on developing unique data sources with high frequency updates for the entire Earth and has over 60 LEMUR-2 class satellites deployed in space complimented with a global ground station network,” Spire Global CEO Peter Platzer said. “Under Pioneer, we can offer our extensive experience in manufacturing and managing small spacecraft like these to those who cannot afford to waste money and time doing it themselves. This work with ESA helps further support the global development of commercial aerospace’s potential to make space access universal.”
“These incredibly clever shoebox-sized satellites built in Glasgow could slash the complexity and cost of access to space, presenting an exciting opportunity for the UK to thrive in the commercial space age,” UK Space Agency Chief Executive Graham Turnock said. “Through our £4m development funding, the government’s Industrial Strategy and by working closely with our international partners, we are helping UK businesses transform their ideas into commercial realities, resulting in jobs, growth and innovation.”
Tersus GNSS Inc. has launched Tersus Oscar, its new generation GNSS real-time kinematic (RTK) system.
Oscar is an all-in-one GNSS receiver that can be used as rover or base system. Paired with a Tersus TC20 controller or A11 mobile terminal, Oscar can more efficiently meet customer application requirements for the optimal surveying solution, according to Xiaohua Wen, founder and CEO of Tersus GNSS.
“Last year, we launched the David GNSS receiver,” Xiaohua said. “This year, we are very excited to introduce an advanced version of David; we named it Oscar.”
Oscar supports calibration-free tilt compensation function, meaning a leveling pole is no longer required. Configuration is made easy with a 1.3-inch interactive screen. With an internal high-performance multi-constellation and multi-frequency GNSS board, the Oscar GNSS receiver can provide high accuracy and stable signal detection, the company said.
The high-performance antenna can speed the time to first fix and improve anti-jamming performance. The built-in large capacity battery can support up to 10 hours of fieldwork.
A radio module in the package supports long-distance communication. With its rugged housing material, Oscar is protected from harsh environments.

Russian positioning satellites could circle the Moon by 2040.
In a draft document describing Russia’s program for lunar exploration, plans include deployment of navigational and communications satellite groupings in lunar orbit.
The document, adopted at a Nov. 28 joint meeting of Roscosmos and Academy of Sciences officials, was obtained by Russian news agency Sputnik, which described it here.
According to the document, the tasks described for 2025-2030 include “the delivery to the Moon of a series of spacecraft for orbital research and the establishment of a global communications and positioning system.”
The concept envisions the deployment of a lunar satellite navigation constellation between 2036 and 2040.
Russia’s Earthly navigation constellation is GLONASS.
A Roscomos press release Nov. 28 says a moon base is the agency’s top priority. “The interest of mankind to the moon is associated primarily with the fact that unique regions with favorable conditions for the construction of lunar bases were discovered on the satellite. The implementation of the lunar program will be held in several stages until 2040.”
Russia will reportedly implement its new strategy in three phases: the launch of an orbital station, a manned mission to the surface, and the eventual construction of a permanent base.
Septentrio has launched the Mosaic high-precision GNSS receiver module.
Despite its compact size (31 x 31 x 4 millimeters, 1.29 x 1.29 x 0.15 inches), the Mosaic module supports more than 30 signals from all six GNSS constellations, L-band and various satellite-based augmentation systems, the company said.
As a multi-band module tracking all GNSS satellites in view, it is also designed to support future GNSS signals.
It also supports correction services, and uses real-time kinematic (RTK) technology, together with Septentrio’s algorithms, to guarantee maximum accuracy and availability. The surface-mount design of Mosaic is optimized for automated assembly and ease of integration, with a full library of well-documented and flexible interfaces.
“Our new Mosaic module represents the best-in-class option for reliable and scalable position accuracy, with integrity,” said Chris Lowet, product manager at Septentrio. According to Lowet, it provides RTK positioning with a power consumption of 0.6-1 W, and requires no or minimal additional components for the design-in. “These characteristics make it an ideal positioning cornerstone for a variety of mass market UAV, autonomous and robotics applications,” Lowet said.

Robustness to interference. Due to the natural weaknesses of distant GNSS signals and a crowded radio-frequency spectrum, GNSS-based services are vulnerable to unintentional radio-frequency interference (RFI). They are also vulnerable to intentional RFI, attacks intended to disrupt receivers by means of counterfeit GNSS-like signals (known as spoofing), and to intentional transmission of RF energy to mask GNSS signals with noise (known as jamming).
To defend against these threats, Mosaic features Septentrio’s AIM+ technology. AIM+ can suppress the widest variety of interferers, from simple continuous narrowband signals to complex wideband and pulsed jammers, the company added. In addition, the integrated spectrum analyzer allows the RF environment around any Mosaic module to be viewed in real time in both time and frequency domains.
Effective interference countermeasures against threats to GNSS signals also require constant knowledge of the changing RF environment. The Mosaic module helps analyze these threats by continuously and automatically monitoring the GNSS frequency spectrum to detect, characterize, log and mitigate interference events when needed.
