Method of resolving ambiguity, method of location of a receiver by radionavigation comprising an ambiguity resolution step and location receiver
Abstract:
Method of resolving ambiguity for determining the main peak of the autocorrelation function of signals transmitted by a set of satellites and received by a receiver of a radionavigation system, a signal received originating from a satellite comprising two received spectral components right and left, the said method comprising the following steps: the right and left components received are demodulated by a BPSK demodulation method the central carrier is tracked by means of a central carrier loop which calculates estimations of central carrier phase errors so as to generate carrier commands, the code is tracked by means of a code loop which calculates instantaneous estimations of code errors so as to generate code commands, wherein the code commands are furthermore generated on the basis of instantaneous estimations of sub-carrier phase errors.
