A method of locating an aircraft in flight by means of a locating device including at least one sensor and a radar, the method including a first phase of determining a position of the aircraft, referred to as the first position, by means of the at least one sensor according to a signal supplied by the at least one sensor, a second phase of determining, at the same time as the first determination phase, a position of the aircraft, referred to as the second position, by means of the radar, and a phase of comparing data associated with the first position and data associated with the second position after which the first position is either validated or invalidated.

Method for locating an aircraft in flight

An inertial reference unit includes a first measurement channel that includes a first high-performance inertial measurement unit for measuring specific forces and angular velocities, a first computing unit able to compute pure inertial data based on the measurements of the first measurement unit; a second measurement channel that includes a second inertial measurement unit of performance lower than the first inertial measurement unit for measuring specific forces and angular velocities; a second computing unit able to compute pure inertial data based on the measurements of the second measurement unit; an integrity check function able to implement a method for checking the integrity of the data of the first measurement channel based and the second measurement channel; and a synchronization device for synchronizing the measurements.
