A method for merging measurements of a flight parameter of an aircraft, from measurements (y, y, y, y) of this parameter supplied respectively by a plurality of sensors (C, C, C, C), comprising: for each sensor (C; C; C; C), computing a deviation (T; T; T; T), proportional to the absolute value of a difference between a measurement (y, y, y; y) supplied by this sensor, and an estimation of the parameter computed from the measurements supplied by the other sensors; comparing each deviation to a corresponding threshold (T; T; T; T); based on the comparisons, determining the presence or not of an anomaly on one of the sensors with a determined total probability of false alarm; and merging measurements to provide a final estimation of the parameter ({circumflex over (x)}).

Method of sensor data fusion

A device for making available navigation parameter values of a vehicle is provided. The device includes components distributed in the following categories: several sensors collecting measurement data relating to at least one navigation parameter of the vehicle; several computers processing the measurement data collected by the sensors and calculating said navigation parameters; several networks linking the sensors to the computers and linking the computers to systems using said parameters. The networks transmit all the collected measurement data to the computers, which calculate a value for each navigation parameter as well as an estimated value of the associated fault, using a single common fusion algorithm.

A device for determining navigation parameters of an aircraft during a landing phase includes a video system including at least one digital video camera arranged on the aircraft, the digital video camera being configured to generate on the aircraft current video data relating to at least one characteristic point on the Earth, whose coordinates are known, and a data processing unit including an extended Kalman filter and configured to determine the navigation parameters on the basis of current navigation data of the aircraft, arising from a satellite navigation system, current inertial data of the aircraft, as well as said video data.

Method and a device for determining navigation parameters of an aircraft during a landing phase

A prediction device for prediction on the ground of characteristics of the position of an aircraft along a path is provided. The prediction device comprises a calculation element comprising a performance and integrity model consistent with a model on board an aircraft. The second calculation element determines precision, integrity and availability information concerning the position of the aircraft along a flight and/or ground path. The integrity information taking account of an integrity of a satellite positioning system and at least one hardware integrity on board the aircraft.
