Attitude Integration Algorithms Design for Strapdown DTG Inertial Systems

摘要

An important concern in the design of strapdown attitude integration algorithms is its residual drift errors, which caused by externally applied vibration and originate in the ARU-sensors dynamical characteristic and incremental data sampling bandwidth limitation. Of special interest this problem is when dynamically tuned rate gyros (DTG-ARS) are implemented in strapdown inertial systems. This paper presents a review of theoretical results concerned with a problem of designing integration algorithms that are tailored to the basic DTG-ARS dynamic characteristics.
