ABSTRACT:
A fast sequencing method and apparatus for use in a radio navigation system of the GPS type. Satellite-coded signals are simultaneously received from a plurality of sources. The signals are decoded in a single channel by multiple samplings of each signal per each signal modulating period. By taking multiple signal samplings per data period, broadband receiver operation is realized, enhancing the suitability of such apparatus for navigation of medium and high g performance vehicles and the like.
