Abstract (en)

[origin: CA3196129A1] The present invention relates to a method for detecting masking of one or more satellites by an obstacle for a GNSS receiver on board a movable carrier, the method comprising the following steps: - receiving (110), for each one of M satellites, a code pseudo-distance measurement and a variation of carrier pseudo-distances; - computing (120) a definite position of the receiver and a computed position of each satellite (S,); - detecting (170) masking of at least one satellite on the basis of the following sub-steps: - computing (171), at a computation instant and for each satellite, a computed pseudo-distance and a pseudo-distance reconstructed at a previous time; - detecting (174) masking of at least one satellite by analysing a magnitude, called residue, computed by applying a least-squares algorithm.
