  • Process and device for estimating the altitude of an aircraft including an inertial reference system, radio altimeters and a poller
    Patent number: 5415031
    Abstract: The invention is a process and a device for determining an estimation of the altitude of an aircraft from at least two independent measurements of the altitude, by polling. The aircraft must include at least one inertial reference system. A signal representing a first or second derivative of the altitude is diverted from the inertial reference system, polling is undertaken on the magnitudes of like order deduced from the independent altitude measurements and from the derivative of the altitude, respectively, and an integration operation is undertaken so as to obtain the altitude estimation.
