A US governmental agency issued findings last week supporting test results showing that LightSquared’s proposed hybrid satellite/wireless technology could interfere with existing GPS technology. The US National Coordination Office for Space-Based Positioning, Navigation, and Timing (PNT) will send its report to the US Federal Communications Commission (FCC), which will issue the final decision as to whether the company can continue constructing its network. Forbes claims the findings “don’t doom LightSquared but increase the pressure on FCC officials to scale back the broad license the company was granted back in 2005 to build a combined ground/satellite communications network with an unlimited number of terrestrial transmitter towers.” Initial testing in June 2011, as well as subsequent tests, found GPS-interference problems. LightSquared asserts that the problems result from existing GPS devices improperly using available frequencies and that manufacturers have ignored US Defense Department standards designed to block interference by transmissions from adjacent frequency bands. LightSquared has asked NASA’s inspector general to investigate PNT vice chair Bradford Parkinson, claiming that his duties as a board member of GPS vendor Trimble Navigation represent a conflict of interest. In October 2011, LightSquared notified the FCC it will take legal action if not cleared to operate. The company reported a $427 million net loss for the first nine months of 2011. Reuters claims LightSquared “could run out of money in the second quarter of this year if it cannot raise additional capital and financing.”  (redOrbit)(Forbes)(Reuters Canada)(LightSquared)(Computing Now – NewsFeed)
