Abstract

Sun-synchronous round orbit was chosen according to the characteristics of small earth observation orbit.The relations between orbital altitude and inclination,nodal period,FOV and swath width and spatial resolution were analyzed on the basis of six general orbital elements.The determination method of descending node and longitude of ascending node were presented.At last,the STK(Satellite Tool Kit) simulation software was used to analyze designated target observation performances of the satellite whose orbital altitude is 560.92 km and 502.59 km.
