Abstract: The satellites of a constellation of satellites each transmit, on distinct frequencies, a first and a second radionavigation signal, respectively. Each station of a reference network from which a satellite is visible performs non-differentiated measurements of code and phase for each of the two signals originating from the satellite and deduces therefrom a raw value of the widelane ambiguity. An internal delay of the satellite and a whole value of the widelane ambiguity are determined, in the network, on the basis of this raw value.
