The embodiment of the invention discloses a method for autonomously maintaining the orbit height of an ultra-low orbit satellite. In one specific implementation mode, the method comprises the steps that the position and the speed output by a satellite-borne GNSS receiver of a satellite serve as input, the actual intersection point period value of the satellite is calculated when the satellite is located at an ascending node or a descending node, and orbit maneuver is executed according to the relation between the actual intersection point period value and an intersection point period target value so as to maintain the orbit height. According to the autonomous maintenance method for the orbit height of the ultra-low orbit satellite, the position and the speed output by the satellite-borne GNSS receiver of the satellite serve as input, electric propulsion and chemical propulsion are combined for implementation, and the advantages that the consumption of an electric propulsion working medium is small and the thrust effect of chemical propulsion is large can be comprehensively utilized, so that in-orbit autonomous orbit maintenance of the orbit height is achieved.
