GPS API

The GPS (Global Positioning System) API provides a method for turtles and computers to retrieve their own locations.

It broadcasts a PING message over the Rednet and waits for responses. In order for this system to work, there must be at least 4 computers used as gps hosts which will respond and allow Trilateration. You can set up hosts using the gps program.

Note: When entering in the coordinates for the host you need to put in the position of the modem, not the computer it is attached to.
