Abstract:
1. A method, carried out by a telecommunication receiver, for identifying a more probable mapping {circumflex over (σ)} between measured pseudo-distances ρ i and transmitters in a plurality of transmitters belonging to a single-frequency network, said transmitters being synchronized and transmitting with an artificial delay τ i , specific to each transmitter, a same radiofrequency signal on one and the same carrier frequency, the method comprising: acquiring, by the telecommunication receiver, as assistance data, an approximate position of the telecommunication receiver {circumflex over (p)}, and a list of transmitters {Tx} located in a vicinity of the telecommunication receiver with respective positions p receiving at the telecommunication receiver radiofrequency signals corresponding to the radiofrequency signals transmitted by the transmitters and measuring, at the telecommunication receiver, pseudo-distances ρ determining at the telecommunication receiver, a more probable mapping {circumflex over (σ)} between the measured pseudo-distances ρ
