Research of strapdown inertial navigation system on laser gyros in the attitude definition mode

摘要

An errors of strapdown inertial navigation system (SINS) working in the attitude definition mode and intended for use in a structure of a magnetic measuring complex are considered. An algorithm and block diagram of the inertial-magnetic system on the basis of Kalman filtering method and the geomagnetic field components definition method are developed. Features of the measuring operational mode and algorithms of SINS working in a structure of a magnetic measuring complex are cited in this paper. A results of research and mathematical modeling both algorithms and errors of SINS are shown.
