Accuracy of Marine Inertial Navigation System(INS) is mainly dominated by gyroscope. In this paper, a new scheme (Inertial Gyrocompass System) is designed to realize high accuracy INS on the basis of low accuracy float gyros and velocity information of Doppler log. By choosing optimal 2-order horizontal damping network and 1-order azimuth damping network and designing logical damping parameter, the positioning error caused by gyro drift can be eliminated to a large extent. Computer simulation and experimentations show this scheme is effective and practicable.
