Considerations for GPS Spectrum Interference Standards

Christopher J. Hegarty

Abstract:	In January 2012, the U.S. National Positioning, Navigation, and Timing Executive Committee (PNT EXCOM) concluded that a nationwide, terrestrial wireless communications network proposed by LightSquared was not viable due to GPS interference concerns. The EXCOM proposed that “GPS Spectrum Interference Standards” be developed to “inform” future commercial proposals to be implemented in bands adjacent to GPS to ensure that such proposals are implemented in a way to avoid interference to GPS and other satellite navigation systems. Based upon lessons learned from the LightSquared situation, this paper identifies a number of important considerations for such GPS spectrum interference standards.
