A Senate investigation into how the Federal Communications Commission (FCC) handled a request to rezone spectrum adjacent to GPS frequencies for LightSquared’s powerful wireless network will continue whether the FCC nixes the plan or not.
Sen. Chuck Grassley, R-Iowa, has been looking into whether the FCC fast-tracked its review of the Virginia firm’s proposal to build a 4G broadband network with signals that would be, tests now show, powerful enough to interfere dramatically with GPS receivers.

In an effort to improve constellation sustainment, on or about Feb. 1, 2012, SVN-49 will resume transmitting an L-band signal using PRN24 as a test asset, according to the U.S. Air Force Space Command. Upon completion of the test event, SVN-49 will once again be decommissioned from active service. PRN24 will then once again be available for future satellite service.
