beacon finder

Outputs the gps location of a beacon, with a good data set to an accuracy of +/- 500 meters.

Designed to be fitted to an aircraft, hook up the microcontroller to its dependancies (gps sensor, beacon pulse signal) and fly in any direction in a straight line. After a distance of 1 to 4km, (variable with distance to beacon, mouse over microcontroller for debug output or connect monitor), turn between +/- 20 to +/- 120 degrees and fly in a straight line for 1 - 4 km. After this it will output gps location of beacon.

To perform the sequence again, toggle the reset pin.

To disable, pull the reset high.

By measuring the distance from the beacon at 3 different points on the map, we can calculate the gps position of the beacon its self.
