== 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
