GSS6400: What intermediate frequencies (IF) are signal recordings stored at?

Environment/Versions
  • GSS6400
        - GPS only model; minimum requirements =  Firmware v3.00 and FPGA v54 and FIFO v58
        - GPS/GLO model; minimum requirements = Firmware v3.00 and FPGA v54 and FIFO v56
        - GPS/GLO/GAL model; minimum requirements = Firmware v3.32 and FPGA v65 and FIFO v66h
Answer

The IF frequency depends on the recorded file type, as follows:-

  • .dat files (GPS only) = 4.092MHz
     
  • .dgp files (GPS only) = 3.98MHz
     
  • .dgg files (GPS + GLONASS) = GPS at 3.98MHz and GLONASS at 6.64MHz
     
  • .dgl files (GLONASS only) = 6.64MHz
     
  • .dga files (Galileo only) = 6.06MHz
