  1. GPS Interference A.T. Balaei A.G. Dempster J. Barnes School of Surveying and SIS at the University of New South Wales and Cooperative Research Center Spatial Information School of Surveying & Spatial Information Systems The University of New South Wales, Australia

  2. Satellite signal Environmental Noise RF Interference (RFI) Received Signal GPS Signal Environmental noise RF Interference Asghar Tabatabaei

  3. RFI in Sydney Asghar Tabatabaei

  4. Where to Look at Interference in the GPS Receiver Antenna Display Navigation Data Processing Radio Frequency Front End GPS Signal Acquisition & Tracking Pre-Correlation RFI Detection Post-Correlation RFI Detection Asghar Tabatabaei

  5. Interference Detection Statistical Inference (Pre-Correlation) Asghar Tabatabaei

  6. Characterization of the Effect of CW Interference (Post-Correlation) Correlation process on signal, noise and interference. The lines have different powers and so the carrier-to-noise ratio C/N0 is differently affected by each line. Here theory is compared with measurements Asghar Tabatabaei

  7. RFI Detector (FPGA) GNSS Signal Quality Post-Correlation C/No Characterisation Pre-Correlation Statistical Inference CORS Network Interference GNSS Data CORS Network Server Asghar Tabatabaei
