As previously announced, the Federal Communications Commission (FCC) International Bureau invited comment today on its proposal to vacate its January 2011 conditional waiver order permitting LightSquared Subsidiary LLC to establish a terrestrial wireless broadband network as a result of demonstrated interference to GPS signals and receivers.

[Updated February 15, 2012] The GPS community received a Valentine’s Day message from U.S. regulators today (Feburary 14, 2012): there is “no practical way” to mitigate potential interference posed by terrestrial transmissions from LightSquared’s proposed wireless broadband network.
Inside GNSS • January/February 2012
GNSS and inertial technologies have a complicated mutual history.
Once competitors for navigation and positioning applications, they now appear ever more frequently in complementary roles — often within the same solution or system design.

U.S. Deputy Secretary of Transportation John Porcari told a congressional committee today (February 8, 2012) that the expenditure of “substantial federal resources” in assisting LightSquared to gain approval for its terrestrial wireless broadband system was “unusual” yet “merited,” but that “further investment cannot be justified at this time.”

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.
