Abstract
An apparatus for generating a precision frequency includes a receiver that tracks a CDMA pilot signal and extracts frequency and phase information. This information is then used by a processor to control a precision oscillator. The precision oscillator generates a precise frequency based on the CDMA pilot signal. Time of day information is also extracted by the receiver and processor.
