File Type: ASCII, comma-separated values

Record Format: Magellan proprietary position and altitude  string with
external datetime stamp.

Data Format Description:
The file contains GPPAT strings prefixed by an external datetime stamp.

Example Record: 03/15/2010,14:08:45.876,$GPPAT,000020.00,4129.52523,N,07125.11232,W,-00021.26,147.6027,-001.76,-000.65,0.0028,0.0351,0*4D

where:
     03/15/2010     Date (source unknown), UTC
                      03   = 2-digit month
                      15   = 2-digit day of month
                      2010 = 4-digit year
     14:08:45.876   Time (source unknown), UTC
                      14     = 2-digit hour [24-hour clock]
                      08     = 2-digit minute
                      45.876 = decimal seconds
