Abstract

Super low altitude remote sensing satellite maintains lower flight altitude by means of ion propulsion to improve resolution and positioning accuracy of imaging images. The design of engineering data for achieving image positioning accuracy is discussed in this paper based on principles of photogrammetry theory. The line-of-sight exact rebuilding of each detection element and this direction intersects with the earth's elliptical precisely are ensured by the joint design of key parameters when the camera on satellite is imaging. These parameters include orbit determination accuracy, attitude determination accuracy, exposure time of camera, synchronizing time of getting ephemeris and attitude data accuracy, geometric calibration and checking precise on orbit. Simulation calculation of precision proves that image positioning accuracy of super low altitude remote sensing satellites is not improved obviously. Attitude determination error of satellite still restricts positioning accuracy.
