Abstract
In the near future a new class of EO-missions will be possible that combine both high resolution imaging and real-time imaging, and therefore will open up room for new fields of applications not feasible today. GEO remote sensing satellite is one of the most important applications of international remote sensing technology academia which has the advantage of real-t ime, continuous observation, rapid revisit capability and rapid response for small or medium scale objects. Currently the international researchers have reached the nadir looking Ground Sampling Distances (GSD) in the order of 20m for VNIR bands (0.45-0.90μm), CCD pixel spatial angle of about 0.55μrad, instantaneous swath of 300x300 km2. This paper analyzes the complicated new features of imaging observation and imaging quality of the GEO optical remote sensing satellite different from LEO. For image quality, this paper points out all aspects and influencing factors of the imaging system chain. Using theoretical analysis, modeling and simulation methods, we research related factors and the degree of influence on the image quality of the satellite imagery full chain. Such research achievements can provide reference for the satellite system design and mission analysis of high-resolution GEO remote sensing satellites.
