By Andrey SolovievSpeaking at a special EGNOS Workshop, Fiametta Diani, head of marketing at the EU Agency for the Space Program (EUSPA), described where Europe’s GNSS augmentation system is going, in the air, on land and at sea.
By Peter GutierrezA deadlock over 5G implementation, and the potential hazards the technology would create for air traffic safety, has been at least temporarily resolved. Not all questions have been answered nor problems eliminated, however. And while radio altimeters do not use GPS or GNSS technology, they are definitely PNT devices, and this situation could create precedents for ongoing and future conflicts between telecom and PNT use of the finite radio spectrum.
By Dawn M.K. Zoldi (Colonel, USAF, Ret.)Two Hexagon I NovAtel employees and a reporter sacrificed their bodies in the name of science by riding in the jump seat of an Aero Albatros fighter training jet during the L-39 demonstrations. Here, we get the perspectives of those brave souls and the mastermind behind the unique human aspect of this experiment.
By Dawn M.K. Zoldi (Colonel, USAF, Ret.)Michael Ritter isn’t afraid to take risks in the name of innovation. And flying a fighter jet with your sensors, employees and a reporter onboard certainly qualifies as risky.
By Alan CameronThe Finnish Geodetic Institute (FGI) of the National Land Survey of Finland announced the release of its software-defined receiver as open source for the international GNSS community. The GSRx software receiver has been extensively used as a research platform for the last decade in different national and international R&D projects to develop, test and validate novel receiver processing algorithms for robust, resilient and precise position, navigation and timing (PNT).
By Inside GNSSEMCORE Corporation, a provider of advanced mixed-signal products that serve the aerospace & defense, communications, and sensing markets, announced that it has entered into a definitive agreement to acquire the assets and liabilities of the L3Harris Space and Navigation Business for approximately $5 million in an all-cash transaction.
By Inside GNSSThe European Union Agency for the Space Programme (EUSPA) has published its Earth Observation (EO) & GNSS Market Report, an outgrowth of its annual GNSS Market Report now that the agency has also taken on Earth observation among its administrative responsibilities. The Report is compiled and written for all those making these technologies part of their business plan and developing downstream applications.
By Inside GNSSSBG Systems announced the tactical-grade Pulse-40 inertial measurement unit (IMU) in a miniaturized size for precision and robustness under harsh conditions, with an excellent size, weight, power and cost (SWAP-C) rating for its category.
By Inside GNSSPhysical Logic of Petah Tikva, Israel received a customer contract for $2 million for continuing development of a new-generation navigation-grade closed-loop micro-electromechanical (MEMS) accelerometer, the MAXL-CL-4000.
By Inside GNSSScientists at Draper Laboratory have patented a celestial navigation system called a sliced-lens star tracker, which in its early form can achieve 50-meter accuracy in GNSS-denied environments. Improvements are expected as the technology evolves. Vehicles of all kinds may be able to benefit when using this system for navigating by the stars.

When a wireless 911 call comes in from a multi-story building, it can be difficult to pinpoint exactly where the caller is—wasting valuable time. NextNav has developed a solution with z-axis capabilities, Pinnacle 911, that addresses this GPS shortcoming, and recently entered into an agreement with a top wireless carrier to leverage it for enhanced 911 (E911).
By Inside GNSSFocalPoint Positioning, founded in 2015, is, as they say, very happening. Its Supercorrelation is a chipset-level software product for mobiles, wearables and vehicles that is changing the positioning game in urban environments. Interesting and energetic, FocalPoint founder Ramsey Faragher came out of the defense industry and has a risen rapidly in the GNSS firmament.
