摘　　要：本文从共线条件方程和前方交会的几何条件出发,推导了异轨和同轨模式下卫星立体定位的精度计算公式,仿真分析了轨道和姿态参数测量精度对卫星测绘能力的影响。实验结果表明,本文推导的精度计算公式正确合理。In this paper,formulas of academic accuracy of stereo positioning in across-track and along-track modes are deduced based on co-linear equation and space intersection geometry conditions.And they are used to emulationally analyze the relation between accuracy of satellite orbit and sensor attitude and the satellite mapping performance.Experimental results show that formulas deduced in this paper are correct and reasonable.
