MITIGATION OF RADIO FREQUENCY INTERFERENCE (RFI) IN GLOBAL POSITIONING SYSTEM (GPS) SIGNALS

摘要

A technology is provided for reducing pulsed radio frequency interference. The GPS signal may be received at a GPS device. The GPS device may include a GPS receiver. The GPS signal may include a plurality of sign and magnitude bits. Pulsed RFI may be detected in the GPS signal based on samples of the magnitude bits in the GPS signal. The pulsed RFI received at the GPS receiver may be reduced by communicating a blank signal when the samples of the magnitude bits indicate the pulsed RFI.
