High-resolution Imaging System of MEO Remote Sensing for Emergency Applications

To meet the needs of various remote sensing emergency applications, a MEO (Medium Earth Orbit) optical imaging satellite system based on elliptical frozen orbit is designed. The system is equipped with a large aperture optical primary mirror and a visible and infrared integrated detection system, which has the imaging mode of wide area search and regional continuous monitoring. Through the fine design and planning of imaging guidance law, the complex imaging application of elliptical orbit can be realized. The satellite has the ability of long-term high-resolution imaging in the area of 5 ° ~ 45 ° north latitude and can meet the needs of various remote sensing emergency imaging applications.
