摘　　要：航天测绘可通过多台线阵相机立体成像、单台线阵相机姿态机动成像、面阵相机立体成像等多种体制实现。文章针对大比例尺(1∶5000~1∶2000)航天测绘任务的实际应用需求,提出了降轨双线阵立体成像、双星编队立体成像等新型实现体制,从原理上分析了不同体制的技术特点,研究了不同体制对于系统设计、有效载荷、卫星平台、地面处理等环节的要求,从测绘效率、测绘精度、工程实现难度等方面对可行的体制进行了比较,可为我国大比例尺航天测绘系统建设提供参考。Space mapping can be achieved through a variety of ways,such as stereo imaging by multiple linear array cameras,attitude maneuver imaging by single linear array camera,stereo imaging by plane array camera and so on.In view of the practical application requirements of large scale（1∶5000-1∶2000）space mapping mission,new systems are brough forth,such as stereo imaging by orbit descending bi-linear array and stereo imaging by bi-satellite formation.The technical characteristics of different systems are analyzed in principle,and the requirements of different systems for the design of satellite system,payload,satellite platform,ground data processing and so on are studied.The feasibility of systems is compared from the aspects of mapping efficiency,mapping accuracy,project implementation difficulty,and so on.This reaseach of the paper provides reference for the construction of large scale space mapping system in China.
