在介绍太阳同步轨道相关知识的基础上,着重分析了该轨道的高度因素,给出了当前在轨太阳同步卫星轨道高度的上下限,介绍了几种典型的低轨道太阳同步卫星,同时给出了太阳同步卫星轨道控制方法的发展状况及趋势,最后综述了当前国内外太阳同步轨道的轨控模式与维持策略。 Based on the introduction of the related knowledge of the sun synchronous orbit, the paper analyzes the height of the orbit, analyzes the upper and lower limits of orbit altitude of the orbiting sun synchronous satellite, and presents several typical low-orbit geostationary satellites The development and trend of the sun synchronous orbit control methods are summarized. At the end of the paper, the track control modes and maintenance strategies of the sun synchronous orbit at home and abroad are reviewed.
