Abstract
A system and method for wirelessly linking a GPS device (12) with a portable electronic device (14) to provide the portable electronic device (14) with GPS functions. The GPS device (12) includes a GPS receiver or sensor (16) operable for receiving GPS satellite signals from a plurality of GPS satellites and a transmitter (18) coupled with the GPS receiver for wirelessly transmitting information corresponding to the GPS satellite signals. The portable electronic device (14) includes a receiver for wirelessly receiving the information transmitted by the GPS device (12) and a display for displaying data corresponding to the GPS satellite signals. The transmitter (18) of the GPS device (12) and the receiver of the portable electronic device (14) preferably wirelessly transmit and receive information via a short range wireless local area network (LAN) using infrared, unlicensed radio, or optical transmission methods.
