LightSquared Network Fails Test

A key federal committee charged with testing the LightSquared network, says there would be significant interference with global positioning systems from the mobile broadband carrier. The National Space-Based Positioning, Navigation and Timing Executive Committee, which is made up of nine federal agencies, unanimously agreed that none of LightSquared’s proposals to combat GPS interference would work.

Under an agreement with the FCC, weaker satellite signal frequencies were used, while the company attempted to resolve the problems. But after testing earlier last year and then again in November, after LightSquared modified its proposal, the committee concluded that neither the original or modified proposals would work.

In its report the National Space-Based Positioning, Navigation and Timing Executive Committee said – based upon this testing and analysis, there appear to be no practical solutions or mitigations that would permit the LightSquared broadband service, as proposed, to operate in the next few months or years without significantly interfering with GPS. is dedicated to serving the agricultural industry in the Carolinas and Virginia with the latest ag news, exclusive regional weather station readings, and key crop market information.
