【 摘 要 】

More and more attention has been paid to taking the Earth as a whole for researching. Though space-borne and airborne platform have acquired various data from the Earth, the existing Earth observation system lack the ability of long-term continuous observation at a global scale. We propose a new platform, Moon-based platform, which is used for observing Earth from the Moon and discuss the coverage performance for observing Three-polar regions. Three-polar regions is characterized by its large scale and need long-term observation. Moon-based platform is the ideal platform. The coverage performance of the Moon-based platform depends on Moon orbit parameters, the attitude of the Moon and the attitude of the Earth. The position of the Moon are calculated from Jet Propulsion Laboratory ephemerides. The attitude of the Moon calculated from the libration Euler angles and the attitude of the Earth derived from the Earth orientation parameters. After introducing the coordinate system transformation, a preliminary coverage geometry are conducted. With the help of coverage geometry model, the simulation about Three- polar regions is presented. The result shows that the Moon-based platform has the advantages of large observing areas, long observation time windows and rich observing angles combination.
