Swift Navigation has completed a 6,600-mile cross-country drive test measuring the efficacy of its Skylark cloud corrections service and demonstrating nationwide lane-level GNSS correction coverage at the accuracy, reliability and availability levels required by its customers.By Inside GNSS
A group of Stanford Ph.D. and Masters graduates, with work experience among them at SpaceX, Ford Motor Systems, Blue Origin, Booz Allen Hamilton and other firms, has launched a start-up to start up a low-Earth orbit successor to GPS and other GNSS. The existing services, they say, are not up to the challenges of autonomy. They founded Xona Space Systems to supplant the venerable satnav systems.By Inside GNSS
The U.S. Air Force updated the GPS Standard Positioning System (SPS) Performance Standard (PS) in mid-April, 2020, the first new Performance Standard document since 2008. It includes mention of and pre-Initial Operating Capability (IOC) performance standards for the new civil GPS signals L2C and L5 for the first time. In another new feature, the document mentions “expanded capabilities which allow the total size of operational constellation to grow beyond the previous maximum of 32 Navstar satellites” for “more robust constellation availability to enhance the overall SPS SIS performance.”By Inside GNSS
GPS satellites usually transmit their signals with constant power. However, a so-called “Flex Power” is foreseen to increase the strength of individual signals to better fulfill operational constraints. Flex power operations can be detected in carrier-to-noise density ratio (C/N0) observations provided by GNSS receivers of the global tracking network of the International GNSS Service (IGS).By Peter Steigenberger, et al.
The Federal Communications Commission ignored a technical standard defining radio-frequency interference. The five commissioners licensed powerful terrestrial broadcast next to the satellite band, exposing national defense and critical infrastructure to harm.
Order-of-magnitude advances in inertial technology seem to take place roughly every 20 years, and the industry is poised at such a point now. New developments in photonic technology make high-performance inertial measurement accessible at lower size, weight and power. Many applications from driverless cars to UAVs can now take advantage of positioning that can independently bridge GPS outages from 2 minutes up to 10 minutes.By Inside GNSS

Just like the kids valiantly doing their homework during this strange, removed time, PNT enthusiasts young and old around the world can put their isolation to good use by honing skills at home. “GPS: An Introduction to Satellite Navigation,” the massive online open course created by Frank van Diggelen and the late Per Enge, is available on YouTube.By Inside GNSS
A new GNSS/INS receiver, the AsteRx-i D UAS from Septentrio, specifically targets integration into unmanned aerial systems (UAS). It provides centimeter-level RTK positioning and 3D attitude. It features a 44 pin connector compatible with 3rd-party integrations, as well as event marker inputs to accurately time-stamp camera shutter events.By Inside GNSS
