Abstract  Abstract

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