摘　　要：研究一种以激光陀螺为角速度敏感器件的寻北系统。通过分析系统的数学模型及各种影响因素,给出系统的简化模型。为抑制系统噪声提高寻北精度,采用Kalman滤波算法进行寻北解算。仿真结果表明,系统工作3分钟即可达到2.387′的寻北精度。A north-finder based on laser gyroscope is studied. The simplified model of the system is given by analyzing mathematical model and various influence factors. In order to reduce the influence of the system noise and increase the north-finding accuracy, a Kalman filter is used. The simulation result show that the system accuracy can achieves 2. 387＇ within 3 minutes.
