Proposed wireless network threatens GPS

LightSquared, a startup wireless provider, has proposed a terrestrial-based wireless network using a portion of the electromagnetic spectrum previously reserved for satellite transmissions, and has petitioned the FCC for permission to do so. Because the portion of the EM spectrum licensed to LightSquared is directly adjacent to the portion used by GPS signals, LightSquared’s high-powered terrestrial antennas will likely “drown out” the relatively weak GPS satellite signals, seriously degrading the quality and effectiveness of GPS devices in the United States. If the FCC grants LightSquared’s petition and the network is implemented, it has the potential for severe adverse effects on the navigational ability of consumer, busines and military GPS devices.
