STUDY OF SINS WORK IN THE CONDITIONS OF HIGH LATITUDES TAKING INTO ACCOUNT THE ERRORS OF REAL SENSORS

摘要

The article proposes an algorithm for the functioning of SINS based on switchable algorithms in the Euler-Krylov angles and quaternions for work on mobile objects at high latitudes and under high values of pitch angle. Variants of the object movement through the north pole as well as execution of dead-loop are considered. The simulation results of the work of ideal system as well as system with taking into account the real sensor errors are given.
