Senate Proposals for GPS Receiver Standards Won’t Solve LightSquared Issue

LightSquared’s proposed broadband service may cause trouble for GNSS receivers, such as this one, that use commercial satellite augmentation services.

The Senate is considering establishment of receiver standards as part of a wide-ranging effort to find more frequencies for wireless broadband services, a move that could ultimately result in expensive new requirements for the GPS community.
