The invention provides a measurement error correction method and system for full-physical simulation satellite sight line pointing. The measurement error correction method comprises the following steps of S1, measuring a rotation center coordinate of a three-axis air bearing table of full-physical simulation equipment, S2, measuring a coordinate component of an exit point of a satellite sight line in a three-axis air bearing table body coordinate system, and S3, in the satellite sight line dynamic measurement process, conducting measurement error correction, and acquiring measurement error correction result information of satellite sight line pointing for full-physical simulation. The measurement error caused by the translation of the emergent point of the satellite sight line can be effectively eliminated, and the satellite sight line pointing measurement precision in a full-physical simulation test is improved.

    本发明提供了一种用于全物理仿真卫星视线指向的测量误差修正方法及系统,包括:步骤S1:测量全物理仿真设备三轴气浮台的转动中心坐标;步骤S2:测量卫星视线的出射点在三轴气浮台本体坐标系下的坐标分量;步骤S3:在卫星视线动态测量过程中,进行测量误差校正,获取用于全物理仿真的卫星视线指向的测量误差修正结果信息。本发明可有效消除卫星视线的出射点平移引起的测量误差,提高全物理仿真试验中的卫星视线指向测量精度。
