Hi Mark:
In the early days of GPS the "poor man's" correction was to do the math on the position. But a better method is to
correct the path for each satellite.
Have Fun,
Brooke Clarke

The controller periodically requests the remote unit's position and just calculates the vector distance/bearing between the two units. The application was intended to work with the boxes spaced 50-5000 feet apart. I was rather surprised how well they worked very close together. The next step is to add a magnetic compass module to the controller box so that it can draw a map of the remote units in relation to the orientation of the controller box.
