LightSquared is calling for a government investigation into a leak of test results that indicated its planned wireless service caused interference with GPS receivers. The results leaked to Bloomberg show that tests in early November found interference with 75 percent of GPS receivers. LightSquared said in a letter to the US Department of Defense and the Department of Transportation that the information was "preliminary, incomplete and did not represent the full findings from the test results". It asked the departments to "refer this matter for an immediate investigation to determine the circumstances of this leak", Bloomberg reports. US regulators have been withholding approval of the LightSquared service while they check the claims of interference. The testing was requested by the National Telecommunications and Information Administration. The company said the results wrongfully assume that LightSquared's wireless network will operate at a power level 32 times greater than the one at which it will actually operate. The NTIA said it's still assessing the situation, noting that "the conclusions to be drawn from the test data will vary depending on factors such as LightSquared's power levels and other technical variables". Official results of the testing won't be released for "several more weeks," said Anthony Russo, director of the National Coordination Office for Space-Based Positioning, Navigation and Timing, which is conducting the tests.
