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.
