M3 Systems and TilT Consulting on June 1 were declared winners of the MyEUspace Competition 2021 for their passive radar for detection and localization of obstacles based solely on GNSS signals.
The SANGENE project (Sens And Navigation on GNSS ENvironment Estimation) aims to demonstrate the concept of an integrated GNSS-based passive radar for the detection and first localization of obstacles.
The SANGENE solution is a passive radar technology based solely on GNSS signals integrated into a localization and navigation device currently available onboard an aircraft or a drone. Today’s operational navigation equipment often use a combination of equipment to identify and locate other carriers or obstacles, but these means do not permit detection and visualization of non-equipped or uncooperative carriers, and can be a source of danger.
As “signals of opportunity,” GNSS signals can be used for detecting obstacles. With reflected signals, GNSS satellites behave as multiple radar signal sources that are widely available while remaining discrete.
This principle of passive detector also makes it possible to increase the localization capacity of the GNSS devices already present, without having any major architectural changes to their design.
Within a few months, this solution has passed from a first level of concept and definition to an implementation model. With the impetus provided by the competition, the validation phase will soon begin.
The MyEUspace Competition was organized by the European Union Agency for the Space Program (EUPSA) to support development of innovative commercial solutions — such as mobile apps or hardware-based solutions — that leverage Galileo or Copernicus EU space data.

Trimble has announced the first deployment of its map-based localization system for land-based autonomous vehicle applications.
IHI Corp., a heavy industry manufacturer based in Japan, will retrofit its existing container and haulage trucks with a customized Applanix POS LV system as part of its broader autonomy capabilities for the transport of goods around industrial facilities.
Map-based localization provides precise positioning and orientation estimation, augmenting GNSS/inertial data, which is critical for safe and efficient autonomous vehicle operations. The ability to provide IHI Corp. a full workflow and real-time data ensures seamless integration into IHI’s truck design.
The custom-built, locally supported system leverages Trimble’s engineering capabilities and technology to provide reliable performance across a variety of challenging environments, the company said. Using this system, IHI Corp. can provide robust positioning for its autonomous fleet without additional site infrastructure, lowering capital expenditure costs and improving scalability.
Tailoring POS LV to work within IHI’s unique specifications and existing autonomous platform, the map-based localization system couples an inertial navigation system (INS) with simultaneous localization and mapping-based (SLAM) capabilities, and works with several types of sensors, including lidar. POS LV provides an accurate base map using post-processed data and localizes vehicle positioning in real time, enabling the reliable and safe autonomous operation of industrial vehicles.
IHI continually enhances its work environments, while also compensating for varying labor scenarios and personnel shortages. This makes the need to automate transportation critical to operations. The complexities of the evolving industrial manufacturing environment require solutions that can be tailored to a customer’s specific application requirements.
By partnering with Trimble, IHI can develop a retrofit system that addresses two major challenges — affordability and reliability — within the autonomous operation of large-scale industrial equipment.

Google has launched the ARCore Geospatial API in ARCore software development kits (SDKs) for Android and iOS across all compatible ARCore-enabled devices.
The application programming interface (API) is available at no cost to download and opens up nearly 15 years of Google Maps data to help developers build more useful and immersive augmented reality (AR) experiences.
“The Geospatial API provides access to global localization — the same technology that has been powering Live View in Google Maps since 2019, providing people with helpful AR-powered arrows and turn-by-turn directions,” explains a Google blog.
“Based on the Visual Positioning Service (VPS) with tens of billions of images in Street View, developers can now anchor content by latitude, longitude and altitude in more than 87 countries, without being there or having to scan the physical space, saving significant time and resources.
“For end users, discovering and interacting with AR is faster and more accurate as images from the scanned environment are instantaneously matched against our model of the world,” the blog states. “This model is built using advanced machine-learning techniques, which extract trillions of 3D points from Street View images that are then used to compute a device’s position and orientation in less than a second.
“In other words, users can be anywhere Street View is available, and just by pointing their camera, their device understands exactly where it is, which way it is pointed and where the AR content should appear, almost immediately.”
Early-access partners include the NBA, Snap and Lyft, who are exploring and building applications in areas such as education, entertainment and utilities. For example, micromobility companies Bird, Lime and WeMo are using the API to remove friction from parking e-scooters and e-bikes, adding pinpoint accuracy so that riders know exactly when their vehicle is in a valid parking spot. Lime has been piloting its app in London, Paris, Tel Aviv, Bordeaux, Madrid and San Diego.
The partnership will help to grow global adoption of the u-blox PointPerfect high-precision positioning service, in particular for automotive applications.
U-blox and Geespace have signed a memorandum of understanding (MOU) on the expansion of their respective augmentation services for high-precision applications.
Geespace is a provider of aerospace information and communications infrastructure and application solutions. Both partners will be able to extend their service offering to the U.S., European and Chinese markets, primarily in the automotive sector.
The rise of reliable and cost-effective high-precision positioning has improved the accuracy of GNSS solutions to the order of tens of centimeters, enabling a plethora of new applications in automotive, as well as industrial and robotics segments. Global adoption has, however, been hampered by a fragmentation of the augmentation services landscape, thee companies said.
For global adoption to become a reality, worldwide coverage is required, as is unified pricing and business models designed to serve mass-market high-precision solutions for automotive and industrial customers operating on a global scale. The resulting differences in technical specifications have also made development of such solutions requiring different services complex.
The MoU between u-blox and Geespace seeks to create a combined offering that will enable both companies to offer full-stack high-precision positioning software and hardware solutions to customers across the U.S., European and Chinese markets.
Also, it will enable Geespace, which provides automotive GNSS augmentation services to its parent company Geely Group, to use the u-blox PointPerfect GNSS augmentation service to grow its coverage to serve Geely’s automotive brands. Headquartered in Hangzhou, China, Geely Group brands include Geely Auto, Lynk & Co, Zeekr, Volvo Cars, Polestar, Lotus, London Electric Vehicle Company, Farizon Auto and CAOCAO Mobility.
The MOU also will enable u-blox to expand coverage of PointPerfect to offer customers a comprehensive high-precision solution for products sold in China, and benefit from simplified development and logistics efforts.

Advanced Navigation has acquired Vai Photonics, a spin-out from Australian National University (ANU) developing patented photonic sensors for precision navigation.
Vai Photonics’ vision, to provide technology to drive the autonomy revolution, is similar to Advanced Navigation’s. It will join Advanced Navigation in commercializing its research into autonomous and robotic applications across land, air, sea and space.
“The technology Vai Photonics is developing will be of huge importance to the emerging autonomy revolution,” said Xavier Orr, CEO and co-founder of Advanced Navigation. “The synergies, shared vision and collaborative potential we see between Vai Photonics and Advanced Navigation will enable us to be at the absolute forefront of robotic- and autonomy-driven technologies. Photonic technology will be critical to the overall success, safety and reliability of these new systems.”
James Spollard, CTO and co-founder of Vai Photonics, explained the technology. “Precision navigation when GPS is unavailable or unreliable is a major challenge in the development of autonomous systems. Our emerging photonic-sensing technology will enable positioning and navigation that is orders of magnitude more stable and precise than existing solutions in these environments. By combining laser interferometry and electro-optics with advanced signal-processing algorithms and real-time software, we can measure how fast a vehicle is moving in three dimensions. As a result, we can accurately measure how the vehicle is moving through the environment, and from this infer where the vehicle is located with great precision.”
The technology, in development for more than 15 years at ANU, will solve complex autonomy challenges across aerospace, automotive, weather and space exploration, as well as railways and logistics.
Aircraft with an electric vertical-takeoff-and-landing system such as flying taxis will greatly benefit from this technology, according to Advanced Navigation. Landing and takeoff are often considered the most dangerous and expensive part of a flight route. Vai Photonics sensors will provide safe and reliable autonomous takeoff and landings under all conditions.
Space travel and exploration is fraught with risks, vast complexity and enormous cost. This technology will bring massive benefits to space missions, helping to cement Advanced Navigation as the gold-standard for space-qualified navigation systems for space exploration.
“The work that underpins Vai Photonics’ advanced autonomous navigation systems stems from the search for elusive gravitational waves — ripples in space and time caused by massive cosmic events like black holes colliding,” said Brian Schmidt, vice-chancellor of ANU. “The team have built on a decade of research and development across advanced and ultra-precise laser measurements, digital signals and quantum optics to build their innovative navigation technology.”

Septentrio, a leader in high-precision GNSS positioning solutions, has launched two new GNSS products for marine applications: AsteRx-U3 Marine and AsteRx-m3 Fg.
Both products offer accurate positioning near shore and offshore via centimeter-level real-time kinematic (RTK) or the built-in Fugro precise point positioning (PPP) sub-decimeter subscription service, delivered either over NTRIP internet or over L-band satellite.
Corrections delivered over L-band allow dredging, bathymetry or marine construction projects even in areas where there is no internet service. The AsteRx-U3 Marine receiver, enclosed in an IP68-rated housing, offers a unique feature of a dedicated L-band demodulator with a separate L-band RF input, which allows for the use of dedicated antennas for excellent reception of L-band signals even at high latitudes.
“The new products are designed around our most powerful GNSS core, bringing the latest evolution in GNSS technology to the demanding marine construction and dredging markets,” said Silviu Taujan, product manager at Septentrio. “They build on the success of the field-proven AsteRx-U Marine Fg and AsteRx4-Fg, with more processing power to allow tracking of all visible satellite signals while enabling higher update rates. AsteRx-U3 Marine and AsteRx-m3 Fg are both feature-rich receivers, combining the best-in-class RTK base and rover functionality with an option of sub-decimeter PPP positioning.”
Orders for both products can be placed immediately. Deliveries for AsteRx-m3 Fg will follow the company’s standard lead times, while deliveries for AsteRx-U3 Marine will start from July.
Septentrio GNSS technology is resilient to RF interference, which on vessels can come from satellite uplinks such as Iridium modems or from other radio antennas. Having robust GNSS technology means accurate and uninterrupted positioning on any vessel, even in challenging marine environments. Both AsteRx-U3 Marine and AsteRx-m3 Fg receivers offer accurate heading and pitch or heading and roll orientation information with the dual GNSS antenna configuration.
The Open PNT Industry Alliance (OPIA) issued a statement regarding the recently approved U.S. Fiscal Year 2022 Appropriations Act. The alliance advocates for support of alternative positioning, navigation and timing (PNT) services.
In its statement, the 21 corporate members express support for the funding provided to the Department of Transportation to pursue alternative forms of PNT.
The OPIA also highlights a change to the National Timing Resilience and Security Act that eliminates the “land-based” technology requirement. The consensus among members is that the adjustment was needed so that the law would allow for multiple forms of PNT, a concept that aligns with the diverse technology principles of the coalition.
The Consolidated Appropriations Act for Fiscal Year 2022 (H.R. 2471) promotes robust positioning, navigation, and timing (PNT) technologies and preserves competition that drives innovation in the market.
Important Funding for PNT Services
The FY 2022 Appropriations Act, passed by the U.S. Congress and signed into law by President Biden on March 15, 2022, provides $15 million for the U.S. Department of Transportation (U.S. DOT) to establish a program that will support the U.S. government’s pursuit of many types of alternative PNT. The legislation aligns with U.S. DOT’s January 2021 “Complementary PNT and GPS Backup Technologies Demonstration Report” and summarizes how the funding will be applied.
OPIA encourages U.S. DOT to apply this funding to procure alternative PNT services and supplementary solutions that will protect critical infrastructure. Our members are prepared to engage civil government officials and critical infrastructure owners and operators to match needs with solutions.
Critical Change to Existing PNT Law
The National Timing Resilience and Security Act of 2018 (NTRSA) focused attention on the need to reinforce GPS. Congress subsequently recognized that NTRSA would be harmful to the commercial PNT market. The FY 2022 Appropriations Act revises the NTRSA to align with the U.S. DOT’s 2021 report that “the best strategy for achieving resilient PNT service is to pursue multiple technologies to promote diversity in the PNT functions that support transportation and other critical infrastructure sectors.”
This straightforward change to the NTRSA is as follows:
“Section 312(a) of title 49 United States Code, shall be amended by striking ‘land-based,’ after ‘operation of a’.” When the revised objective of the NTRSA is read in context, it is evident that the law is now fully inclusive of multiple forms of alternative PNT:
Subject to the availability of appropriations, the Secretary of Transportation shall provide for the establishment, sustainment, and operation of a land-based, resilient, and reliable alternative timing system (1) to reduce critical dependencies and provide a complement to and backup for the timing component of the Global Positioning System (referred to in this section as “GPS”); and (2) to ensure the availability of uncorrupted and non-degraded timing signals for military and civilian users in the event that GPS timing signals are corrupted, degraded, unreliable, or otherwise unavailable.
This move by Congress comports with the findings of the U.S. DOT’s report on PNT which state that “suitable and mature technologies are available in the private sector and offer owners and operators of critical infrastructure a diverse array of complementary PNT services to meet their GPS backup needs. Because such needs are application-specific, GPS resilience across all critical infrastructure sectors will require a plurality of diverse PNT technologies to meet multiple use cases.”
The commonsense modification to the NTRSA allows multiple alternatives to GPS and other global navigation satellite systems (GNSS) to deliver against a complex and ever-expanding set of institutional and end-user requirements.
The alignment with OPIA’s bedrock principles is clear:
A diverse technological landscape offers varied operational characteristics to support all critical infrastructure sectors.
True resilience requires diversity that a sole-source technology cannot meet in terms of reliability, performance, and the flexibility to address evolving attack prevention and threat response needs.
The ingenuity of the private sector marketplace will drive the emergence of multiple cost-effective GPS/GNSS alternatives that evolve according to technological innovations and market dynamics.
Open PNT Industry Alliance members provide what critical infrastructure needs for resilience: alternative forms of PNT that complement GPS/GNSS as well as augmentation services, security solutions, and hardware/software for time synchronization, navigation and location applications.

The data also is being processed to create a fully rendered mesh model suitable for use in a range of GIS, CAD and modeling software packages Acquired using the Leica CityMapper aerial sensor that simultaneously captures vertical and oblique imagery together with high-point density lidar, MetroVista data is becoming increasingly popular for smart city applications. Providing a geographically accurate and detailed 3D representation of the urban environment, MetroVista data provides insight for applications such as urban design, defense and security modeling, insurance assessments and utility and telecom planning.
WindNinja is a high-resolution wind modeling app created for firefighters who need to quickly compute and visualize wind direction and speed simulations. The simulations provide them with situational awareness, help keep them safe, and help them conduct work such as burnout operations. The mobile app, developed using ArcGIS AppStudio from Esri, provides high-resolution, near-surface wind forecasts that include wind speeds and directions displayed on a map. The user selects an area of interest of 50 square kilometers or less, names the simulation, chooses a forecast duration of up to 15 hours, selects whether to receive an email or SMS notification when the simulation is ready to view, and then submits the request. The user also can select from a variety of basemaps and turn on data layers — vegetation, atmospheric, oceanic, land-surface imagery — collected by NOAA satellites.

The AT-MX intelligent control system for shared electric bicycles uses the latest ultra-low-power u-blox M10 GNSS technology to enhance the positioning performance of their fleet for improved compliance with increasingly stringent Chinese policy requirements. The growing popularity of shared micromobility solutions for short-distance urban travel has led municipal authorities around the world to introduce new legislation to mitigate their perceived negative impacts, for instance, with restrictions on where users can drive and park their vehicles. Meanwhile, vehicle operators and maintenance personnel need to efficiently locate vehicles requiring maintenance and gather reliable vehicle usage data to balance bicycle placement and operational safety. Enforcing regulatory compliance and optimizing operations both require the safe, accurate and efficient bicycle positioning solutions.
