Settings to change to improve combined accuracy of trajectory

To be used in POSGNSS and Grafnav:

• Reduce elevation mask (to min 10)

• 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

• Measurement -> standard deviation (change to something that matches the mean of the red line on the graph under CA filter)

• Lower the satellite horizon - you might do this to accept more satellite if there are an inadequate number covering an area (minimum 5 for decent quality)

• 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
