Abstract: Estimating the speed of an aircraft estimates three components of the speed vector (TAS, AOA, SSA) of an aircraft relative to the surrounding air. The static pressure is estimated on the basis of measurements of geographical altitude. A first intermediate variation of a linear combination of the three components of the speed vector of the aircraft relative to the surrounding air is estimated using explicitly the fact that the pressure measured by the static probe is falsified by a known quantity under the effect of the three components of this speed vector of the aircraft relative to the surrounding air. The process then estimates the three components of the speed vector of the aircraft relative to the air by likening the latter to the speed vector of the aircraft relative to an inertial reference frame and by using inertial measurements. The various estimates are fused to provide a final result.

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. The method includes, for at least one considered pair of geolocation devices made up of a first geolocation device (Gm) and a second geolocation device (Gn), computing (34) a deviation statistic between a first position vector computed by the first geolocation device and a second position vector computed by the second geolocation device, and computing (36) an alarm statistical threshold (S(m,n)) based on the deviation statistic and a first predetermined probability (PFA). The method makes it possible to raise a malfunction alarm by using the computed alarm statistical threshold. The invention also makes it possible to compute (44), for at least one geolocation device of each pair of geolocation devices, an integrity radius from the alarm statistical threshold and a second predetermined probability (PND).
