System and method for determining the position of a wireless CDMA transceiver

A system and method for determining a position of a mobile wireless transceiver. A Doppler shift of signals transmitted from first and second satellites, respectively, relative to a base station is calculated. A first set of pseudo ranges of the first and second satellites, respectively, relative to the base station is also calculated. Satellite identification information, Doppler shift information, and the pseudo range information between the base station and the wireless transceiver is sent to wireless transceiver. The wireless transceiver use the information received from the base station to identify a second set of pseudo ranges between the wireless transceiver and the first and second satellites, respectively, at a time tx. The wireless transceiver sends the second set of pseudo ranges between the wireless transceiver and the first and second satellites, respectively, along with time information tx to the base station, in response to which, the base station calculate the position of the wireless transceiver.
