This AWK script was initialized by "dogps" - shell script run under CYGWIN v. 1.5.1 (UNIX like environment that runs under Windows). This is the script used for the May 12 data collection:
files=`ls *.gps | cut -d. -f1` for file in $files do awk -f awkhold $file.gps $file >> day1gps.txt doneThe script not only parses the GPS navigation, but concatenates the results into a single file. This script was repeated for day 2 and day 3 (May 13 and May 14 respectively) with the output directed to day2gps.txt and day3gps.txt.
