From ACSM, summarized:
Lightsquared has filed a petition with the FCC asking for a Declaratory Ruling that:
1. Manufacturers and users! of unlicensed commercial GPS receivers (are there any such licensed receivers?) lack standing to complain etc about interference from Lightsquared's transmitters.
2. Commercial GPS receivers have no right to protection from Lightsquared's operations in adjacent bands.
3. GPS devices which receive interfering signals from Lightsquared's transmitters are non-conforming and are not entitled to any protection, licensed or not.
4. Costs of filtering out Lightsquared's transmissions so that GPS receivers will operate properly are the responsibility of the GPS manufacturers, not Lightsquared's responsibility.
I would say this is probably a last-ditch effort by Lightsquared's CEO to save his mortally wounded investment. There's going to be a LOT of angry GPS users if the FCC makes the requested Ruling.
They seem to be pulling out all the stops. You only need a license from the FCC to transmit not to receive and I don't know of any GPS RECEIVERS that transmit over the L1 band. It's akin to having to license your FM radio in you car. More hogwash from the PR machine.
