摘　　要：针对舰载光电经纬仪标校过程复杂、标校条件要求严苛的问题,提出一套舰载光电经纬仪标校方法。该方法在通过装舰前的陆基标校,装舰后的艏艉线标校以及拍星标校修正了光电经纬仪、惯性导航系统与舰船的坐标系转换矩阵,进而提升装备的空间指向精度。该标定方法操作简便,可在舰船动态条件下进行,能有效地完成光电经纬仪的标校工作,提高设备的安装效率。实装结果表明,采用该方法标校后的舰载光电经纬仪的实时空间指向精度优于20″。Aiming at the complex calibration process and strict calibration conditions of shipborne photoelectric theodolite,a new calibration method for shipborne photoelectric theodolite was put forward.This method improves the spatial pointing accuracy by correcting the coordinate system conversion matrix between the photoelectric theodolite,inertial navigation equipment,and the ship through land calibration,center line calibration,and star calibration.This calibration method is easy to operate and can be carried out under ship dynamic conditions.It can effectively complete the calibration work of the photoelectric theodolite on the ship and improve the installation efficiency of the equipment.The actual installation results show that the real-time pointing accuracy of the shipborne photoelectric theodolite calibrated by this method is better than 20″.
