ABSTRACT:
A receiver for a navigation satellite system such as NAVSTAR, including an antenna for receiving an incoming coded, time-based, spread spectrum signal which includes navigational data from a plurality, P, of satellites, a circuit for deriving baseband I and Q components of each of the signals, circuitry for digitizing the I and Q components, a Fast Fourier Transform (FFT) processor for transforming the digitized I and Q components and their respective codes, and a multiplier for multiplying together the transformed components and codes derived for each of the P satellite signals and to inverse transform the signals and to then determine correlation peaks in the inverse transformed signals.
