Lightsquared Test Show 75% of GPS Receviers Affected


To those in the GPS community, Lightsquared and their potential interference with GPS receivers is pretty well understood, but for many, the story is just starting to gain some momentum. There is new information out on the proposed Lightsquared wireless internet service that operates in a spectrum close to the GPS frequency that shows that 75% of GPS receivers tested are affected by the Lightsquared system. That's bad news for people who use a GPS in their phone for location services, and in their navigation device for directions. With the GPS receiver becoming ubiquitous as smartphones take over the world, the Lightsquared service looks like it could cause broadscale issues.

This testing, conducted by the US Government, was done at a higher power, and Lightsquared expects that the propsed lower power operating protocol will "only" harm 10% of GPS receivers within 100 yards of a Lightsquared base station. With 40,000 base stations planned, that's a lot of area; about 100 square miles of affected area where 10% of you will lose the ability to operate your GPS correctly. Ouch.
