Abstract

A satellite positioning receiver with integrity check and exclusion of defective axes. In order to improve the reliability of the measurements which are divergent with respect to the measurements provided by the other satellites in the constellation which is used at a given time. The invention proposes a solution for more rapidly recalculating the position by eliminating the data from a defective satellite: the means for calculating the position vector X on the basis of n satellites include an iteration process with n steps, the j.sup.th step involving the j.sup.th satellite; a position X' is recalculated using only n-1 satellites on the basis of the n steps already calculated, by adding an (n+1).sup.th iteration step, using the measurements from the defective satellite of rank m, this last step being slightly different from the previous ones and the difference being such that the calculation result after this (n+1).sup.th step is identical to that which an iteration with n-1 steps excluding the divergent satellite of rank m would give.
