Recent tests “did show that LightSquared signals caused harmful interference to the majority of other tested general-purpose GPS receivers,” according to a statement issued yesterday by Anthony Russo, director of the National Coordination Office, on behalf of the National Executive Committee for Space-Based Positioning, Navigation and Timing.
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.
The FAA supplemental type certificate for Garmin’s GTN series touchscreen avionics has been validated by EASA, and the GTN 650 and 750 can now be installed in aircraft registered in Europe.
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.

One of the pleasures of attending the many aviation trade shows on our annual to-do list is the opportunity to see new aircraft, products and people. I’m sure many of the “new” exhibitors that I run across every year have probably been exhibiting for years and I just haven’t noticed them, but it’s still fun to meet new people, like Maxim Antonov of Avioconversiya (no relation to the Russian aircraft designer).
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.
The Coalition to Save Our GPS sent a letter today to the FCC asking the agency to “promptly rule” that LightSquared be barred from using the upper mobile satellite spectrum (MSS) band for high-powered terrestrial operations.
