Draft data covering recent DOD and FAA tests of cellphones and other consumer GPS devices revealed that 75 percent “experienced harmful interference” when within 100 meters of a LightSquared base station, according to a report in Bloomberg News on December 9.

LightSquared reported yesterday that results of testing by an independent laboratory “confirmed that several major high-precision [GPS] receivers…are 100-percent compatible with LightSquared’s network.” LightSquared is seeking government approval to
LightSquared is coming under pressure from several separate directions, as opponents to its plans provide more specific support to their positions on legal, financial and technical issues. And in the background, a telecom industry heavyweight with whom LightSquared hopes to form an alliance wants clarity by year-end.
NBAA helped to pioneer the transition to GPS-based flight decks and procedures, and now the group is taking a leading role to voice the U.S. civil aviation community’s concern about LightSquared’s threat to GPS.
After LightSquared made statements that it has a “legal right” to build a network of terrestrial 4G broadband transmitters in the U.S., the Coalition to Save Our GPS last Thursday stepped up its attack of the company’s plans.
Clearly impatient with the way the company’s plan for its nationwide broadband Internet project is becoming further and further delayed by opposition from the GPS user community, several federal government departments, members of Congress and, reportedly, within the FCC bureaucracy itself, a LightSquared
Honeywell, the only U.S. company to be chosen as an original member of the Sesar Joint Undertaking tasked with developing technologies for post-2020 air traffic management in Europe, demonstrated work in progress at its research center in the Czech city of Brno last week. One project is an initial four-dimensional (I4-D) trajectory planning system involving the flight management system (FMS) and communications management unit.

The Coalition to ‘Save Our GPS,’ through vice president and general counsel Jim Kirkland of founding member Trimble, has responded to claims by LightSquared, which is seeking approval for a terrestrial broadband communication service in a frequency spectrum very close to that of GPS.
Can GPS and LightSquared coexist? Within the civil and military GPS community, the answer has been emphatically and unequivocally, “No.” Until last week, that is. Attendees at the annual convention of the U.S. Institute of Navigation held in Portland, Ore., had been confident that the laws of physics made coexistence of the two impossible.
