Повышение точности определения угловой скорости быстровращающихся объектов
Abstract
Application of Strapdown Inertial Navigation Systems (SINS) to highly spinning vehicles imposes very stringent and in most cases unrealizable requirements to scale factor errors of angular rate sensors (ARS). Various techniques for accuracy improvement of measurement of angular rate along the rotation axis are analyzed. A solution without additional hardware is proposed. This solution is based upon the forced regular precession of a vehicle. This precession allows estimating the spin rate around the longitudinal axis with the help of outputs of cross angular rate sensors; these angular rate sensors are part of the principal inertial measurement unit. Algorithms implementing the proposed technique are analyzed, and the results of simulation are discussed.
