Yundong Han, Yunhai Zhong, Su Wang, Guohui Lan, Wei Li


It is important practical significance for the further research to establish the gyroscope motion model with much error conditions and its simulation platform for the type of electromagnet control gyrocompass as the main reference point to provide a true instrument. According to its working principle, the mathematical model of the direct heading and constant velocity motion of the gyrocompass is established by analyzing the influence of velocity error, latitude error and inertial error. Then the simulation model is established with SIMULINK, and the rationality and accuracy of model is also verified through the comparison of simulation data and the actual observation results.
