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.

The White House wants to maintain the pattern of steady investment in the GPS program though it appears the administration has decided to go more slowly on deployment of the new GPS III Follow-on (GPS IIIF) satellites.

The chairman of the Federal Communications Commission (FCC) told two U.S. Senators in January that his agency could not complete a decision on Ligado Network’s license modification by the end of 2019 because of a late-in-the-year response from a key federal agency.

In a letter made public late Friday, the point person for all federal agency use of frequencies told commercial spectrum regulators his agency could not support approval of Ligado Networks’ request to use satellite frequencies for a terrestrial wireless network.

Professor David Last described his life in crime during the Institute of Navigation’s GNSS+ 2012 conference. He was late coming to that line of work, he noted, having only been tapped by the police after his retirement from teaching at the University of Wales.

The Defense Department urged spectrum regulators this week to reject a proposal by Virginia-based Ligado Networks to build a wireless terrestrial communication system that could, it said, interfere with GPS.

The Department of Transportation (DOT) selected 11 firms to demonstrate technologies that could be used to back up the services provided by GPS should GPS signals be jammed, spoofed or unavailable.

The grapevine was abuzz on Halloween with chatter that the Federal Communications Commission (FCC) might soon act on a long-pending request from Ligado Networks to use spectrum near the GPS frequencies to support terrestrial communications.

The U.S. Army is reaching out to industry for the advanced inertial measurement unit (IMU) and timing technology it needs to support warfighters when GPS is unavailable or compromised.

The software and hardware development phase of the new GPS ground system program is now complete and the team is moving on to integration and testing, prime contractor Raytheon said in a statement.

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.

Key officials from the BeiDou and GLONASS programs, affiliated organizations and members of the satellite navigation industry met at the end of August to fine-tune a cooperation deal between the two systems.

The Department of Transportation (DOT) will launch, in a matter of weeks, the contracting process to perform field demonstrations of different GPS-backup technologies.
