Improving the trajectory

Settings that can be changed in POSGNSS and Grafnav:

  • Change ionosphere settings (top part)
  • Increase KAR1 maximum distance for dual frequency (especially if your basestation is more than 30km away)
  • Process more or less of the flightline. Cut out sections of the track if they have significant gaps (right click on the track and set start/end time in the appropriate places, then reprocess)
  • Measurement -> standard deviation (change to something that matches the mean of the red line on the graph under CA filter)
  • Lower the satellite horizon (elevation mask). You might do this to accept more satellites if there are an inadequate number covering an area. Don't go below 10 though.
