METHOD OF PROCESSING RADIO-NAVIGATION SIGNALS

摘要

PROBLEM TO BE SOLVED: To provide a method of resolving phase ambiguity of non-differential measurement performed by a receiver (on earth or in orbit) based on a raw code and phase measurements.SOLUTION: Each satellite in a constellation of satellites transmits first and second radio-navigation signals at different frequencies, and each station of a control network, from which a satellite is visible, performs non-differential measurement of code and phases for each of the two signals from the satellite to deduce a raw value of wideband ambiguity from measured values. Internal delay of the satellite and a whole number of wideband ambiguity in the network are established based on the raw value.
