Global Navigation Satellite Systems Engineering, Policy, and Design
Microchip Technology’s new time and frequency server with an embedded M-Code GPS receiver gives protection to military communication systems, radar and networks from the threats associated with intentional GPS jamming and spoofing, as well as cybersecurity risks to critical infrastructure.

As the final BeiDou satellite reaches geostationary orbit, experts in the satnav community worry about security implications of the now officially operational Chinese system. As a two-way rather than a one-way communication system, BeiDou differs in two key aspects from other GNSS:

The Satellite-Based Augmentation Systems Interoperability Working Group has grown from 4 members in 1997 to more than 10 now, and logged significant progress in forming a global aviation support system.
U.S. Sen. Jim Inhofe (R-Okla.), chairman of the Senate Armed Services Committee, announced that he has placed a hold on the nomination of Mike O’Rielly to a third term as Federal Communications Commision (FCC) Commissioner until O’Rielly publicly commits to vote to overturn the current Ligado Order.

An on-board spoofing detection unit collects metrics from the GNSS signal processing chain and provides a real-time indication if the receiver is under spoofing attack. Test results from several spoofing scenarios are based on GNSS hardware simulations, repeaters and software-defined radios.

When we find ourselves in times of trouble, it can help to take the long view. Pull back, zoom out, range free. Consider a vastly enlarged scope and sequence.
That’s why I find this month’s NTS-3 story so welcome. “Next-generation technologies across space,” I keep repeating.
By Alan Cameron
This advanced geosynchronous satellite from the Air Force Research Laboratory will mature next-generation technologies across space, ground control, and user equipment segments. NTS-3 will experiment with multiple integrated technologies.
Ramjack Technology Solutions and Syntony GNSS have partnered to deliver underground GNSS positioning, navigation and timing (PNT) solutions, using Syntony’s SubWave technology.

The European Commission cut its space budget for the next seven years but kept the Galileo and Copernicus satellite programs largely on track. The move came after intense negotiations over a 1.8-trillion-euro European Union budget seeking to absorb and remedy economic impacts of the coronavirus pandemic.

The European Space Agency (ESA) has recently launched an internal initiative to cull ideas for supporting its member states in the study and analysis of the COVID-19 pandemic. Under this initiative ESAC’s Galileo Navigation Science Office has managed to get one of its ideas taken up under the name of the “COVID-19 Space Hunting Platform”.

The European GNSS Agency (GSA), the operational agency of the European Commission for Galileo and EGNOS, is launching its MyGalileoDrone competition on July 17. This contest is targeting the design and development of drone-based applications or services, using a Galileo-enabled receiver, that address the EU’s key priorities such as the Green Deal, and support the EU Recovery Plan for Europe.
