Global Navigation Satellite Systems Engineering, Policy, and Design
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 marine-certified quad-band GNSS receiver, the LD900 from VERIPOS, delivers accurate and reliable positioning in demanding offshore environments. The LD900 can track four GNSS frequencies simultaneously to ensure a precise position is always available at sea.

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.

Federal Communications Chairman Ajit Pai’s step this week toward approving Ligado Networks’ request to use its satellite frequencies for a terrestrial 5G service comes after nearly a decade of testing that showed both versions of their proposal would interfere with GPS users.

We stand at an existential crossroads while someone else decides our future. I don’t mean the choice of direction, currently roiling the front pages, that pits the national health against the national economy. No, this one doesn’t get the attention it deserves, outside of the PNT and the telecom communities, though arguably it could have equally long-running and widespread, perhaps catastrophic effects.

“Ligado’s planned usage will likely harm military capabilities, particularly for the U.S. Space Force, and have major impact on the national economy,” two ranking Senators and a Representative wrote. The timing could not be worse, they said to allow what “is fundamentally a bad deal for America’s national and economic security.”

Thirteen agencies responsible for much if not most of the nation’s military, civil, security and economic activity say Ligado Networks’ plan to use satellite frequencies for 5G communications would interfere with GPS users in general and DOD use in particular.
