The invention discloses an ultra-low orbit satellite high-precision attitude control system and method. The system comprises an attitude measurement sensitive module, an attitude controller and a control execution mechanism, wherein the attitude measurement sensitive module is used for measuring attitude information of a current satellite; the attitude controller is used for combining the attitude information of the current satellite and adopting a preset control strategy to solve the control quantity input of the control execution mechanism; and the control execution mechanism is used for generating torque influencing satellite attitude motion according to control quantity input so as to control the satellite attitude in a mode of alternately using reaction flywheel control and air injection control. Based on the propulsion system, the reaction flywheel and the magnetic torquer, the full-interval high-precision high-stability attitude control target for the ultra-low orbit satellite is realized.
