Method and system to improve GPS navigation

A method and system are provided for improving the navigation accuracy of a vehicle guided by the global positioning system (GPS). The system can be permanent or can be delivered on station" by delivery vehicles dropped from a host aircraft. If delivered, each delivery vehicle travels to a destination at the earth's surface on land or at sea. At each destination, an antenna and a GPS receiver use GPS signals and determine the position of the antenna. A transmitter coupled between the GPS receiver and the antenna transmits the determined position of the antenna over the air waves via the antenna. In this way, a plurality of earth-bound GPS positions can be used by a GPS-guided vehicle to improve its navigation accuracy thereby eliminating the atmospheric errors associated with satellite-transmitted signals."
