Engineering Physics Annotation << Back CORRECTION OF AUTONOMOUS INERTIAL NAVIGATION SYSTEMS OF AIRCRAFT CHZHAN SINKE, K.A. NEUSYPIN, A.V. PROLETARSKY The problem of algorithmic accuracy increase of autonomous inertial navigation systems of aircraft is investigated. A platform inertial navigation system is considered. A correction scheme for an autonomous inertial navigation system using internal information and a correction algorithm based on signals from precession angle sensors are presented. Formalized dependences of the deviation angles of the gyro platform on the precession angles in the first and second approximations are formed, which are used as measurements for the Kalman filter. The errors of the autonomous inertial navigation system and Kalman adaptive filter are simulated. The simulation results showed the effectiveness of the proposed algorithms. Keywords: aircraft, inertial navigation system, autonomous mode of operation, precession angle sensor, correction algorithm, Kalman filter, correction accuracy.
