INSTRUMENT ERRORS OF A STRAPDOWN ATTITUDE REFERENCE UNIT FOR A SPINNING VEHICLE: AN ESTIMATION TECHNIQUE AND SOME RESULTS

摘要

Propagation of common instrumental errors of angular rate sensors (ARS) into the errors of an inertial Strap-down Attitude Reference Unit (SARU) for a spinning vehicle is considered. A technique of error estimation is proposed; its application to the error analysis under free rotation of a moving vehicle is discussed.
