Abstract  Abstract

A PRECISION CARRIER FREQUENCY SIGNAL TO CALIBRATE A LOCAL OSCILLATOR (56) FROM A GPS RECEIVER THAT IS USED TO ACQUIRE GPS SIGNS. THE PRECISION CARRIER FREQUENCY SIGNAL IS USED TO CALIBRATE THE LOCAL OSCILLATOR, SO THAT THE OUTPUT OF THE LOCAL OSCILLATOR, WHICH IS USED TO ACQUIRE GPS SIGNS, IS MODIFIED BY A REFERENCE SIGNAL GENERATED FROM THE PRECISION CARRIER FREQUENCY SIGNAL . THE GPS RECEIVER EXAMINES (53) THIS PRECISION CARRIER FREQUENCY SIGNAL AND GENERATES THE REFERENCE SIGNAL. IN ANOTHER ASPECT OF THE INVENTION, SATELLITE STORAGE DATA IS TRANSMITTED TO A REMOTE GPS RECEIVER UNIT (20) FROM A BASE STATION (12) THROUGH A COMMUNICATIONS LINK. THE REMOTE GPS RECEIVER UNIT USES THESE SATELLITE STORAGE DATA TO DETERMINE APPROXIMATE DOPPLER DATA FOR SATELLITES THAT ARE IN VIEW OF THE REMOTE GPS RECEIVER UNIT.
