A method and device for identifying a faulty satellite among a set of satellites S1, . . . , SN from pseudo-ranges between a mobile and the satellites S1, . . . , SN. Particularly, the method includes, following detection of a satellite failure, steps of: for each satellite Si of the set of satellites S1, . . . , SN: obtaining a set Pi of positions of the mobile, each position pi,j being determined from the pseudo-ranges associated with the satellites S1, . . . , SN by excluding: the satellite Si; and at least one other different satellite Sj for each position pi,j; determining a dispersion indicator al for the positions of the set Pi; and identifying the faulty satellite among the set of satellites S1, . . . SN as a function of the dispersion indicators σ1, . . . , σN.
A method for identifying a faulty satellite among a set of satellites S1, . . . , SN from pseudo-ranges between a mobile and the satellites S1, . . . , SN, the method comprising, following a detection of a satellite failure, steps of:
The method according to claim 8, wherein the positions of the mobile are determined by using a Bancroft algorithm.
A device for identifying a faulty satellite among a set of satellites S1, . . . , SN from pseudo-ranges between a mobile and the satellites S1, . . . , SN, the device comprising an identification module configured, following a detection of a satellite failure, to:
