Settings to change to improve trajectory

To be used with 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.
