Abstract  Abstract

(57) Abstract: A precision carrier frequency signal that calibrates the local oscillator (56) of a GPS receiver used to acquire GPS signals. The fine carrier frequency signal is used to calibrate the local oscillator so that the output of the local oscillator used to acquire the GPS signal is modified by the reference signal generated from the fine carrier frequency signal. The GPS receiver locks (53) to this precision carrier frequency signal and generates a reference signal. In another aspect of the invention, almanac data is transmitted from a base station (12) to a remote GPS receiver unit (20) via a communication link. The remote GPS receiver unit uses the almanac data to determine approximate Doppler data for satellites in the field of view of the remote GPS receiver unit.
