Abstract
A method for processing radionavigation signals coming from satellites that broadcast the radionavigation signals on at least two distinct frequencies, comprises The global positioning comprises, for each satellite, the determination () of a pseudo distance by means of an ionosphere-free combination of the measurements of code and of the difference of the phase measurements, compensated for the widelane ambiguity, this ionosphere-free combination being optimized in terms of noise. The pseudo distance is determined by receiving the satellite clock values associated with the ionosphere-free combination from the reference system.
