Blog Editor’s Note: A good overview article by RNTF International Advisory Committee member, Guy Buesnel. 

It is good to see this message getting to places like India and to read about progress in Europe.

Adding on to the article’s European info, we understand that the EU has selected companies for their demonstration of GNSS alternative technologies. Companies are being notified now, we understand. Once that is complete, we will see an announcement of all the selectees and presumably get information about next steps.

At one point the EU had said it would select a technology to complement and backup GNSS by the end of this year. We suspect that this schedule may have shifted to the right.


Need for Resilient PNT Has Never Been Greater

Real-world instances of Global Navigation Satellite System (GNSS) jamming and spoofing have been steadily increasing in recent years. High-profile incidents include spoofing attacks on hundreds of commercial ships in the Black Sea and repeated GNSS jamming affecting commercial aviation in Norway.

During 2019 alone, pilots reported more than 3,500 instances of GPS jamming, air traffic management organization  Eurocontrol recently disclosed.


In the U.S., the Federal Communications Commission has conditionally approved an application by satellite communications provider Ligado Networks to deploy a low-power terrestrial nationwide network in the L-band to support 5G and IoT services. The decision means that GNSS systems and devices must be capable of resisting adjacent-band radio-frequency interference at extremely high power levels while still providing extremely accurate and precise data to users.

Meanwhile, most, if not all, of the major GNSS providers are experiencing space, control, and user-segment issues. The transmitted data from satellites can contain errors or be corrupted to such an extent that it becomes practically unusable.
