    3131     1. The base station location will come in a particular datum/coordinate system - you '''must''' correctly convert this to a form that POSGPS knows about.
    3232     1. For UK base stations, see the instructions below for this conversion.
     33   1. Loading the airborne settings in POSGPS (''Settings -> Load Settings From -> Airborne'')
     34   1. Process differential (button looking like a blue world with a ruler on it).  This brings up a set of options.
     35     1. Change the ''Process -> Process Information -> Desc'' each run so you can compare between results.
     36     1. Try a run with the default settings first, then investigate other options as needed (see notes below for typical issues)
     37     1. Read the output for hints as to problems
     38     1. Iterate as often as needed
     39   1. When processing is complete, the track will be coloured according to the quality of the data.  The important parts should be green!

    3442---------------
     
    6775 1. Take the lat/long/ellipsoidal height from the ''XYZ to lat,long,H'' sheet and enter into POSGPS (you may want to save these as a favourite too)

     80If the data quality isn't good enough, then you can change some of the settings to effect improvements / admit more data.
     81 * 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)
     82 * increase KAR range - up this if your base station is a long way away
     83
