Abstract: A consolidation method implementing: a first sensor able to determine a computed position {circumflex over (x)}(1) of the aircraft, a characterization of the positioning error and a horizontal protection level HPL(1), a second sensor, with a different design and with a design level equivalent to the first sensor, able to determine a second position {circumflex over (x)}(2) of the aircraft and a characterization of the positioning error of the second position {circumflex over (x)}(2), and comprising the steps: a. estimating a horizontal deviation between the computed position {circumflex over (x)}(1) and the second position {circumflex over (x)}(2), b. comparing the horizontal deviation with a detection threshold, c. if the horizontal deviation is below the detection threshold, computing an additional horizontal protection level HPL(MON) of the computed position {circumflex over (x)}(1), d. estimating a consolidated horizontal protection level HPL(CON), e.

Abstract: The invention relates to a method and a device for verifying the integrity of position vector information obtained by at least two satellite geolocation devices, each of the geolocation devices being able to receive a plurality of wireless signals from a plurality of separate satellites, and to use the received wireless signals to compute a position vector of said geolocation device, including position coordinates computed in a predetermined spatial reference at a given moment in time, each of the geolocation devices being independent of the other geolocation devices, the satellites used being able to be different from one geolocation device to the next.
