The invention provides a phase difference maintaining method of a sun synchronous satellite and a satellite orbit control method, and relates to the field of satellite orbit control, and the phase difference maintaining method comprises the steps: obtaining a plurality of groups of first operation parameter data of a first sun synchronous satellite, and obtaining a plurality of groups of second operation parameter data of a second sun synchronous satellite; fitting the first operation parameter data to obtain a first flat semi-major axis trend line equation; fitting the second operation parameter data to obtain a second flat semi-major axis trend line equation; calculating a difference value as a height difference trend line equation; according to a height difference trend line equation, the predicted height difference of the two satellites is calculated in sequence; and respectively carrying out orbit control at the epoch moment when the orbit control starts, and adjusting the actual height difference to be within a height difference threshold value, so that the phase difference between the two satellites is not changed. One sun synchronous satellite in the two satellites can be controlled at a certain fixed height or the height difference of the two satellites can meet a certain fixed value, and accurate control over the orbit height is achieved.

    本发明提供一种太阳同步卫星的相位差保持办法及卫星轨道控制方法,涉及卫星轨控领域,该相位差保持办法,包括:获取第一颗太阳同步卫星的多组第一运行参数数据,获取第二颗太阳同步卫星的多组第二运行参数数据;对第一运行参数数据进行拟合得到第一平半长轴趋势线算式;对第二运行参数数据进行拟合得到第二平半长轴趋势线算式;计算差值作为高度差趋势线算式;根据高度差趋势线算式,顺序计算双星的预测高度差;在本回轨控开始的历元时刻,分别进行轨控,将实际高度差调整到高度差阈值之内,使得双星之间的相位差不变。能够将双星中的一颗太阳同步卫星控制在某一固定高度或将能够实现双星高度差满足某一固定值,实现轨道高度精准控制。
