US satellite/terrestrial venture LightSquared is calling for an investigation into a leak of testing results concerning the compatibility of LightSquared’s technology with GPS receivers.
On 9 December, Bloomberg published an article that cited a draft summary of testing carried out by the National Space-based Positioning, Navigation and Timing (PNT) Systems Engineering Forum.
According to Bloomberg, 75% of the tested GPS receivers experienced harmful interference at the equivalent of 100 metres in distance from a LightSquared base station.
LightSquared’s chairman and CEO, Sanjiv Ahuja, claimed in a letter that LightSquared had “suffered serious and substantial injury as a result of this leak”.
The comments were made in a letter addressed to the deputy secretaries of the Departments of Defense and Transportation.
In the letter, Ahuja also disputed the interpretation of the test results. He wrote: “Based on our own review of the test data, we profoundly disagree with that conclusion. To achieve that level of threshold of failure, the leaked internal analysis assumes that the power levels of LightSquared networks are 32 times greater than the power levels at which LightSquared will actually operate.”
Ahuja called for an investigation to determine the circumstances surrounding the leak and to make sure that the people responsible would be held accountable.
