The invention discloses an imaging control system of an earth observation satellite. The system comprises a control center, a ground imaging camera and a track maintenance subsystem, the frequency frame of the ground imaging camera is adjusted in real time according to a relative satellite of the satellite and a target point, and the orbit maintenance subsystem comprises an inertial acceleration measurement unit and a small thrust execution unit and is used for realizing satellite orbit autonomous maintenance based on continuous small thrust so as to ensure stable flight during satellite imaging.

    一种对地观测卫星的成像控制系统,包括控制中心,对地成像相机以及轨道维持子系统,其中,对地成像相机的频帧根据卫星与目标点的相对卫星进行实时调整,轨道维持子系统包括惯性加速度测量单元及小推力执行单元,用于实现基于持续小推力的卫星轨道自主维持,以保证卫星成像期间稳定飞行。
