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.

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.

Britain’s own satellite navigation system, envisioned to fill the country’s Galileo void created by Brexit, may never see the light of day. Government officials don’t want to spend tax revenues to meet projected increasing costs.

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.

A new mobile app, Galileo Green Lane, facilitates the free movement of freight, reduces waiting times at European Union borders, and prioritizes essential goods during pandemic response. The app uses Galileo positioning services to address the needs of border control authorities and truck drivers, with two intuitive user interfaces. The app was developed by the European GNSS Agency (GSA) in collaboration with the European Commission.

In its order allowing Ligado Networks to use satellite frequencies for on-the-ground wireless, the Federal Communications Commission set conditions on the firm’s operations, but only at the very tail end. Those conditions are there to help protect GPS receivers from interference — interference the FCC acknowledges as being quite possible.

Though the FCC approved Ligado Networks’ request to use satellite frequencies to support terrestrial 5G, opposition to the move remains firm as everyone waits to see what kind of measures are included in the final decision to protect GPS from interference.

The Department of Homeland Security is offering to test GPS equipment used in critical infrastructure to see how resilient it is against spoofing.
The effort is part of the GPS Testing for Critical Infrastructure or GET-CI program supported by DHS’s Science and Technology Directorate.

The five members of the Federal Communications Commission voted unanimously to approve a request by Ligado Networks to use satellite frequencies neighboring those used by GPS to broadcast from ground antennas for 5G, the agency announced Monday morning.
