Abstract
The invention concerns a method for controlling the integrity of the value of a piece of navigation information delivered by a merging/consolidation device including a plurality of processing modules. Each module generates a navigation solution from measurements coming from one or a plurality of separate navigation devices, which involves defining, for each processing module, a radius of protection, corresponding to a given probability of failure. The method includes defining at least one consolidated area that encompasses protection areas centered on the solution values that are output from the processing modules and that correspond to the radii of protection defined for these modules. The radius of protection of the merging/consolidation device for the probability of failure itself is defined to correspond to the consolidated area.
