Patent ID: 8089397

Claim:
Method of processing radionavigation signals that originate from a satellite of a constellation of radionavigation satellites, said satellite broadcasting at least a first radionavigation signal on a first frequency and a second radionavigation signal on a second frequency that is different from the first, in which method one determines, at the level of a reference network comprising at least one reference receiver, from which said satellite is visible, an internal satellite delay and an integer wide-lane phase ambiguity value for said reference receiver, this determination of the internal satellite delay and of the integer wide-lane phase ambiguity value comprising the steps: receiving said first and second radionavigation signals at the level of said reference receiver; by means of said reference receiver and for each of the first and second received signals, executing a non-differentiated code measurement and a non-differentiated phase measurement; computing a raw value for the wide-lane phase ambiguity from the non-differentiated code measurements and from the non-differentiated phase measurements; fixing the internal satellite delay together with the integer wide-lane phase ambiguity value based on said raw value for said reference receiver.
