As a result of a proposal by a private company to use radio frequency bandwidth right next to the existing GPS radio bandwidth, the future reliability of the GPS system across the United States is now in question.
Synopsis Summary Conclusion of United States Global Positioning System Industry Council
The General Location/Navigation (GPS) sub-team has concluded that all phases of the LightSquared deployment plan will result in widespread harmful interference to GPS signals and service and that mitigation is not possible.
1) The LightSquared Base Station 4G LTE signals harmfully interfere with High Precision, Timing, and Network GPS receivers over long ranges.
2) The LightSquared Base Station signals cause harmful co-channel interference with the FCC licensed StarFire and OmniSTAR augmentation systems.
3) LightSquared handsets, when operated close to a GPS receiver, harmfully interfere with it.
The Aviation Sub-team concluded that all three phases of the currently proposed LightSquared deployment plan are incompatible with aviation GPS operations absent significant mitigation, and would result in a complete loss of GPS operations below 2000 feet above ground level (AGL) over a large radius from the metro deployment center.
