The 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).

The 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.

Scientists 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).

FocalPoint 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.

Locata Corporation and Ursa Navigation Solutions, Inc. (UrsaNav) announced a technology partnership aimed at providing resilient PNT solutions to national governmental and commercial interests globally. Combining Locata’s high-accuracy local-area and UrsaNav’s very wide-area PNT produces a solution which lessens dependency on easily disrupted and increasingly vulnerable space-based signals, according to the two.

Future miniaturized sensors, to be used for example in bee-sized drones, mini-satellites, or wearable devices, are likely to include GNSS chipsets supporting accurate outdoor localization and also offering reduced computational costs and power consumption compared to traditional GNSS receivers. The survey various energy-efficient methods for GNSS acquisition and present a discontinuous-reception acquisition algorithm, analyzed with both simulated and measurement-based data.
