Abstract
The invention proposes a system for excluding a failure of a satellite suitable for a hybrid navigation system and which operates even in case of degraded geometry of the constellation of satellites. The hybrid system according to the invention comprises a plurality M of hybridization filters (SFH1, . . . SFHM) each receiving at least one satellite positioning measurement (MPS) carried out on the signals received from all the satellites in visibility of the said system and an inertial positioning measurement (MPI) and delivering a corrected positioning measurement, the so-called hybrid measurement (MHS1, . . . MHSM), the hybridization filters being updated, at a constant temporal rate, successively at periodically shifted temporal instants.
