针对工作在静座桅杆条件下的光电设备，提出一种低成本的方位角度检测方法。采用2个倾角仪检测光电设备的俯仰轴和倾斜轴的角速度，用1个陀螺检测光电设备的方位轴角速度，完成光电设备方位角度变化量的解算。在已知初始方位角度的情况下，获取光电设备的实时方位角度值。实验表明，采用0.01的倾角仪和零偏稳定性为0.015/h的激光陀螺，方位精度达到0.009。
Abstract
Aiming at the photoelectric equipment working on the stationary base mast,a low cost measurement method of azimuth was presented. The azimuth variation of photoelectric equipment was computed by using two dip instruments to measure the angular velocity of the equipments pitch axis and roll axis and using one gyroscope to measure the angular velocity of the yaw axis. The real-time azimuth was computed when the beginning azimuth was gotten. The theory and system construction of the method were analyzed. The results of prototype test show that when using 0.01 dip instruments and 0.015/h gyro,the real-time azimuth precision is 0.09.
