Abstract :
Gyroscope is the main error source in independent navigation system besides initial angle error and accelerometer zero error. In this paper, Inertial Gyrocompass system is designed by deep analysis of INS model. By mean of involving horizontal damping network, azimuth damping network and optimal choose of damping network parameter, inertial Gyrocompass can bring high precision location on the basis of low accuracy float gyros and velocity information of Doppler log. Computer simulation and experimentations show this scheme is effective and practicable.
