This program commuicates with a Garmin GPS25LP engine that is integral with out locator.
This program was written to test GPS antennas in the field.
The program uses the "sting parse.vee" program that I got from one of you guys on the reflector to separate the NMEA strings into their individual parameters.
To make this program useable with direct communication to a Garmin GPS unit then the port needs to be set to 4800 baud, and plug the comms lead into the com1 port on the PC.

The program takes the NMEA strings and converts the Lat Long (WGS84) into UK local Grid using the "Lat Long 2 grid.vee" program as an imported library.  It also gives a plot of positions, estimated vertical and horizontal errors, and also the satellite information (Azimuth, Elevation, and Signal to Noise Ratio dB).
