<p>A cooperative location system for use with a Global Positioning System ('GPS'). The system includes a beacon that receives GPS signals and transmits GPS data representing the location of the beacon to a remote locator. The locator receives the beacon's GPS data from the beacon. Based on the beacon's GPS data, a reference direction provided by a compass, and the locator's own GPS data, the locator calculates range and direction information to the beacon.</p> |
