      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.

+     1. Try a run with the default settings first, then investigate other options as needed (see notes below for typical issues)
+     1. Read the output for hints as to problems
+     1. Iterate as often as needed

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