A special board formed to advise the federal government on the clash between Global Positioning System receivers and LightSquared’s proposed cellular/satellite communications network has concluded there are “no practical solutions or mitigations” that would allow the two to coexist on adjacent segments of the radio spectrum.
The National Space-Based Positioning Navigation and Timing Committee, in a letter released this afternoon, said it had reached the “unanimous conclusion” that the LightSquared network would “cause harmful interference to many GPS receivers” as well as a GPS-powered ground-alert system overseen by the Federal Aviation Administration.
Based upon this testing an analysis, there appear to be no practical solutions or mitigations that would permit the LightSquared broadband service, as proposed, to operate in the next few months or years without significantly interfering with GPS. As a result, no additional testing is warranted at this time.”
Recall that LightSquared’s business strategy is based not on new technology, but on using its political connections to obtain a competitive advantage. That’s why they aren’t giving up despite all the technical findings against them: they think their politicians still might prevail.
