Abstract (en)
[origin: WO03054576A1] The invention concerns a method using at least a pair of antennae, which consists in carrying out: a standardized spectral analysis before intercorrelation of the demodulated signals (I, Q), by the code and the carrier, resetting phase coherence of the signals before recombination, measuring phase difference carried out by a true intercorrelation of homologous satellite paths by interferometry of two signals derived from a common satellite and received respectively by a pair of antennae, then in reducing the search domain of the initial ambiguity removal to determine a vehicle attitude by interferometric GPS measurement and implementing a statistical test for ambiguity selection.
