NTS-3 Satellite Prepares for Launch to Experiment with Ways to Improve GPS.
Nearly 50 years ago, there were no smart phones, no GPS-guided weapons, no turn-by-turn direction systems in automobiles.

The Pentagon has requested $1.3 billion in its fiscal 2024 budget for bolstering the GPS system, preparing new satellites for launch and moving to a new control system. The biggest changes will come with the new GPS IIIF satellites, still a few years away.

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.

Ligado Networks is pushing spectrum regulators to make a decision on its request to allow satellite frequencies near the GPS band to also be used for terrestrial 5G networks.

The GPS community made real progress during 2018. The first GPS III satellite was launched, the contractor for the GPS IIIF satellites was chosen and work on the new ground system appeared to be on a good track. In addition, after years of waiting, two of three requested Galileo signals were approved for official use in the United States and Congress ordered the building of a backup system for GPS timing.

The new Cybersecurity Solarium Commission should consider addressing GPS vulnerabilities as it develops a strategy to protect the U.S. against attacks on its computer systems and infrastructure, experts agreed.
Inspired by an analysis that guided officials during the Cold War, the U.S. is about to launch a yearlong assessment of its cybersecurity situation with the goal of devising a long-term strategy

Mike Rogers, a key lawmaker in military space policy, appears willing to stick with the current program to build a more capable and cyber-secure GPS ground system despite his profound frustration with schedule delays and cost overruns and a recently revealed report from MITRE Corp. suggesting it be dropped.

The Federal Communications Commission (FCC) has declined to take action on concerns expressed by the GPS community, approving an Iridium request to modify its earth station licenses to take advantage of the advanced capabilities of its second-generation constellation.

The Federal Communications Commission is being asked to choose between the immediate benefits of officially improving U.S. satellite navigation receivers and the possibility that, in doing so, it may raise interference levels in a neighboring band or make it harder to develop alternative uses for those adjacent frequencies.

Most folks look to a new year as an opportunity for fresh starts and new projects. For the GPS community, however, the October 1 start of the 2016 federal fiscal year (FY16) will likely be more about the hangover — that is, the issues that are hanging over into the next 12 months, unresolved.
At the top of that list of unfinished business are two system decisions: a go/no-go determination on whether the United States will build eLoran as the U.S. backup to GPS and deciding whether or not to choose a new contractor for the GPS III program.
