Abstract:
An integrated position determination and radio system comprising:a housing;a receiver including an antenna disposed within said housing for receiving position determination signals from satellites;a first radio disposed within said housing for transmitting information to and receiving data from other position determination systems;position signal processing circuitry disposed within said housing adapted to analyze position determining signals so as to determine the position of said housing, said position signal processing circuitry adapted to be removed from said housing and replaced with a relay circuit board and a housing top having provision for mounting a second radio therein;radio signal processing circuitry disposed within said housing and adapted to demodulate radio signals received from other position determination systems and deliver them to said position signal processing circuitry so as to more accurately determine the position of said housing, andwherein, upon replacing said position signal processing circuitry with said relay circuit board and said housing top having provision for mounting a second radio therein, and upon placing a second radio therein, said integrated position determination system is adapted to relay radio signals received from other position determination systems.
