Abstract:
A method for coupling a position determination message from a first Position Determination System (PDS) device to a second PDS device comprising:a) monitoring, at said first PDS device, radio transmissions over a plurality of radio channels for assigning a radio channel that is unoccupied; b) generating a position determination message at said first PDS device, said position determination message indicating said assigned radio channel; c) transmitting to said second PDS device said position determination message from said first PDS device, said position determination message comprises position data for utilization by said second PDS device; d) updating said assigned radio channel periodically such that said assigned radio channel indicates an unoccupied radio channel; and e) repeating b) through d) such that subsequent position determination messages are transmitted over unoccupied radio channels.
