The U.S. Space Force ordered replacement of the computer hardware in the new GPS ground system due to the due to the sale of IBM’s computer product line to a Chinese company, and the consequent cybersecurity risk posed by the IBM hardware in use.

“Galileo is a true European success story,
and I am proud if in a small way I have contributed to building Europe with it.”
European Union space mainstay Carlo des Dorides, Executive Director of the European GNSS Agency (GSA) since 2011, retired from this post at the end of January. He was scheduled to speak at the 12th EU Space Conference in Brussels that month, but had to skip out when he was called to a special budget session of the European Parliament. It would have been his last appearance in a public forum as GSA chief. Inside GNSS met with him in Brussels to talk and to say farewell.

When the White House submits its budget request for the Department of Defense to Congress every year, that is not the final word. The different military services also send Congress their unfunded priority lists, which detail the projects the White House chose to forego but, the services hope, Congress will add back in. This year several of those priorities are GPS-related.

Due to the proliferation of personal privacy devices and other jamming sources, it is imperative for safety-critical GNSS users such as airports and marine ports to be situationally aware of local GNSS interference. This article proposes and validates an enhanced method for geolocating GNSS interference sources so that jammers and spoofers can be found and disabled.

Seventeen years after federal regulators restricted a promising wireless technology to protect GPS and other spectrum users, they are being asked to loosen those limitations. Ultra-Wide Band (UWB) proponents insist the strictures are too tight and cut off their ability to innovate.
