GPS Receiver Susceptibility to Ultra-Wideband RFI: Test Results and RFI Link Analyses

Robert J. Erlandson and A. J. Van Dierendonck

Abstract:	Ultra-wideband (UWB) system proponents are intent on gaining FCC authorization for Part 15 unlicensed operation across roughly the 0.5 – 6 GHz frequency range. This range contains several restricted frequency bands used for government radio-navigation (e.g., GPS), radar, and communication signals. It also contains many other commercial services such as UHF TV, AMPS and PCS cell phones, DARS, and C-Band DTH TV broadcast. Because of potential impact, NTIA, DOT and others have been studying RFI compatibility of various receivers, especially GPS, with UWB emissions. This paper documents RFI susceptibility assessments of aviation approach and E-911 GPS receivers and recommends compatible UWB emissions for those applications.
