摘　　要：为满足立体测绘卫星的设计要求,通过构建三线阵CCD影像的摄影测量估算模型,对三线阵CCD影像的立体测绘精度进行分析,研究了影响立体测绘精度的主要误差源.进而,依据立体测绘的精度要求,对卫星设计中所涉及的有关主要误差源,如GPS定位系统、姿态测量与控制系统、时统以及相机有效载荷系统,提出了相关的技术要求和保证测绘精度所应采取的技术措施.To conform to design requirements of the stereo mapping satellite, the estimation model of photogrammetry for three-line array CCD images was established, the precision of stereo mapping using three-line array CCD images was analyzed, and the main error sources affecting the precision of stereo mapping were studied. According to the demand of stereo mapping precision, the technical requirements were put forward for the GPS system, attitude surveying and control system, time system and payload system, which are the main error sources involved in the satellite design. The technical measures that should be taken to ensure the precision of stereo mapping were brought forward as well.
