A collection of utilities to read from gpsd and translate between GridSquare and Latitude/Longitude.

This program uses libgps to read data from gpsd running on the localhost (hard-coded to localhost on port 2947), and will display a valid latitude and longitude. Additional information will be output to stderr, including when an invalid position is received.

Given a latitude and longitude, this program will calculate its gridsquare using calculations from https://n1sv.com/PROJECTS/How%20to%20calculate%20your%208-digit%20grid%20square.pdf

Given a six-character gridsquare, this program will calculate the approximage latitude and longitude that corresponds.
