Patent ID: 8346517

Claim:
A method of validating an inertial unit of a moving body on board an angular movement simulator, said movement simulator being located at a point having fixed coordinates in the terrestrial frame of reference, and said validation being implemented by comparing a trajectory of said moving body as calculated in a real navigation environment with at least one reference trajectory, said method including, in order to obtain said calculated trajectory, a stage of piloting said moving body, said stage comprising a plurality of iterations, and each iteration comprising: a data-obtaining step of using a simulation tool modeling said inertial unit in said real navigation environment and fed with piloting commands calculated at the preceding iteration, to obtain: a point of said calculated trajectory of said moving body; simulation inertial data representative of the inertial data that ought to be supplied by said inertial unit in said real navigation environment; and movement commands representative of a movement to be executed by said movement simulator; a step of said inertial unit supplying measurement inertial data representative of said movement after it has been executed by said movement simulator; a theoretical modeling step of theoretically modeling said measurement inertial data supplied by said inertial unit from movement data concerning the movement really executed by said movement simulator for said movement, said theoretical modeling step supplying theoretical inertial data; at least one compensation step of at least one error that might falsify said theoretical modeling of said measurement inertial data by the theoretical inertial data, said at least one compensation step being implemented before said theoretical modeling step; and a step of calculating piloting commands from said simulation inertial data, said theoretical inertial data, and said measurement inertial data.
