Method and apparatus for minimizing of a fault as a result of the interfering movement in the determination of the speed in a inertia mes system

摘要

The present invention relates to a method and device (16) in order to minimize in a strapdown inertial measurement system the error due to any perturbing motion in the reproduction of the speed. & br / according to the invention, said device (16) is connected to a set of accelerometers and to a set of gyrometers and it comprises: & br / - a first computer peripheral (17) capable of performing the multiplications vector; & br / - a second computer peripheral (18) capable of carrying out of the products of the vector; and & br / - a central computer (19) connected to said first and second computers peripherals (17, 18) and coordinating the different computations.
