摘　　要：惯性测姿设备应用于动基座条件下的姿态测量时,其姿态角通过光电准直经纬仪等光学设备向目标传递。为了确保传递精度,惯性测姿设备与姿态传递设备之间的姿态关系需进行标定。动基座下,光电准直经纬仪对准惯性测姿设备的基准立方镜测量,利用同步数据采集器对惯性测姿设备、伺服稳定平台和光电准直经纬仪进行同步数据采集,依据姿态角的坐标转换建立传递方程组,通过求解方程组中的未知参数,实现惯性测姿设备和传递设备之间姿态关系的动态标定。利用惯性测姿设备和传递设备进行试验,验证了该动态标定方法的可行性。Under moving base condition,the attitude angle of the inertial attitude measurement equipment is transmitted by optical equipment such as photoelectric collimation theodolite.In order to realize the high-precision transmission,the attitude relationship between inertial attitude measurement equipment and attitude transmission equipment needs to be calibrated.Under the condition of dynamic base,the photoelectric collimation theodolite measure the reference cube mirror of the inertial attitude measurement equipment.The synchronous data collector is used to synchronously collect data from the inertial attitude measurement equipment,servo stability platform and photoelectric collimation theodolite,and establishes the transfer equation system according to the coordinate conversion of the attitude angle,and realizes the dynamic calibration of the attitude relationship between the inertial attitude measurement equipment and transmission equipment by solving the unknown parameters in the transmission equipment.The inertial attitude measurement equipment and the transmission equipment are used to verify the feasibility of the dynamic calibration method.
