摘　　要：针对驻车情况下光电桅杆系统的工作特殊环境,提出基于光电校正INS的光电桅杆方位角度修正方法。采用光电系统定时瞄准某一固定目标,获得参考方位角修正光电系统中惯性导航系统(INS)的方位角误差,然后采用该误差修正INS的方位角,实现抑制INS的方位角误差发散,提高长时间工作情况下光电系统方位角精度。实验表明,在桅杆摆动造成光电系统瞄准目标时的等效方位角误差为0.06°的情况下,以STIM300作为IMU的INS,采用提出的修正方案在60min内的方位角误差为0.059°,而没有进行修正时在31min内的误差发散到1.14°。According to the special situation of optoelectronic mast system working in parking state, a method for correcting azimuth of optoelectronic mast based on inertial navigation system （INS） calibrated by optoelectronic system was researched. The optoelectronic system was utilized to regularly aim a static target, and the reference azimuth was got to correct the azimuth error of the INS of optoelectronic system . Then the divergence of the azimuth error of the INS was restrained to improve the azimuth accuracy of the photoelectric system under a long time work. The results of experiment show that, under the situation of 0. 06° equivalent azimuth error caused by the mast swing interference when it aiming the target and using STIM300 as the IMU, the INS azimuth error is 0. 059° in 60 min using the correction method proposed and 1. 14° in 31 min without correction.
