Abstract

A collision avoidance system for a plurality of vehicles equipped with GPS receivers, each broadcasting current location information to other vehicles and receiving and displaying location information from other vehicles, enables a vehicle operator to be aware of the location of the other vehicles. For vehicles not equipped with GPS, and transceivers, information about location is taken from common ground control equipment such as an FAA control station and broadcast to all vehicles. In an aircraft environment, flight plans can be filed and closed out automatically.
