<p>The invention relates to a method of monitoring the integrity of stations for observing radio-navigation signals in a satellite based augmentation system SBAS comprising the following steps: - Defining a geographical zone comprising a plurality of observation stations, - Calculating, for each observation station of the said zone and for each line of sight between the said station and a satellite, the discrepancy between the theoretical pseudo-distance D and the measured pseudo-distance D', - Calculating the average m of the said discrepancies D-D over the said zone for at least one satellite in visibility of the said zone, - Validating the integrity of at least one observation station of the said zone if the said discrepancy, for the said station and for at least one line of sight between the said station and a satellite, is less than or equal to the said average that is multiplied by a predetermined exclusion threshold, and excluding this observation station in the converse case.</p> |
