After Seeking FCC Extension, LightSquared Has a New Plan for GPS

Results of John Deere test of LightSquared’s effect on high-precision GPS receivers

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.

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.

Completion of Satellite Repositioning Optimizes GPS Constellation

Completion of Satellite Repositioning Optimizes GPS Constellation

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.

Test Results: LightSquared Would Cause Serious Interference to GPS Receivers

Las Vegas site for LightSquared/GPS tests

Tests of GPS receiver vulnerability to transmissions from terrestrial base stations in the proposed LightSquared 4G/LTE broadband service were scheduled to wrap up on May 27, but results as we post this message clearly indicate substantial adverse effects on GPS user equipment.

On June 1–2, the Technical Working Group (TWG) set up by the LightSquared-led working group mandated by the Federal Communications Commission (FCC) will have its first face-to-face meeting since the trials began to sort out the results.
