Abstract
Remote Sensing Image Simulation, which provides the image according to the characteristics of sensor in geometry, spectral and radiometry, is a very significant issue before the satellite's launching. This paper is mainly detailed in the geometric characteristics of multi-spectral sensors and the process of image geometric simulation of 1A microsatellite in Environment and Disaster Monitoring Microsatellite Constellation (HJ-1A). The relationship among the swath, the convergent angle, and the Ground Sampling Distance (GSD) is studied. The ideal photography model based on the photogrammetric theory is set up according to part of orbit parameters and reasonable assumptions. The relationship between the image coordinates and the geodetic coordinates and the simulating image algorithm is put forward. Finally, some conclusions are drawn up from the results of the study.
