Presentation Transcript

  1. GNSS SDR Technology Survey of the “ipexSR” Software Receiver • High end, multi-frequency, real-time capable • Tracks civil signals coming from all-in-view GPS / Galileo / SBAS satellites • User code (C or MATLAB) can be used at all levels • Input IF samples from • triple frequency (L1 or E1, L2, L5 or E5a) USB Front-End (real-time processing) • recorded data files (post-processing) • single frequency L1 frontend • Measurement accuracy levels • < 30 cm for code measurements • ~1 mm for carrier phase measurements

  2. GNSS SDR Technology Double Difference Correlator Values • Provide complex prompt correlator values for post-processing • Form double differences at correlator level • Do carrier phase tracking at double difference level • Expected improvement: 6-20 dB RINEX carrier phase
