In what looks like a pre-emptive strike in the wake of extensive evidence that its proposed terrestrial wireless broadband transmissions will interfere with GPS receivers, LightSquared today (June 20, 2011) proposed to solve the problem by cut the power of its base stations in half and temporarily use a bandwidth further away from GPS.

LightSquared Gets Two-Week Extension on GPS Interference Report; Congressman Calls on FCC to Rescind Waiver
With test results and congressional sentiment running against it, LightSquared has received a two-week extension for filing its report and recommendations, due to the Federal Communications Commission (FCC) yesterday (June 15, 2011), on likely interference to the GPS L1 band.
Meanwhile, a congressional critic of LightSquared's effort to roll out a 4G/LTE broadband cellular service adjacent to the GPS frequency has called on the agency to rescind its waiver of limits on the company's plans to build a high-powered national network of terrestrial transmitters.

Successful completion today (June 15, 2011) of the rephrasing of the GPS constellation known as “Expandable 24,” has produced the most optimal geometry in the system’s 42-year history, maximizing GPS coverage for all users worldwide.
The 2nd Space Operations Squadron (2 SOPS) of the 50th Space Wing at Schriever Air Force Base, Colorado, successfully executed the two-phase expansion and repositioning of satellites, which improves global GPS coverage and provides a more robust signal and higher probability of signal acquisition in terrain-challenged environments.

A belated response from Julius Genachowski, Federal Communications Commission (FCC) chairman to Republican Senator Charles Grassley’s request for documents surrounding the LightSquared effort to broadcast near the GPS L1 band appears unlike to satisfy either Grassley or the GPS community.
