The embodiment of the invention provides a satellite attitude control method and device and a satellite, and relates to the technical field of aerospace, and the satellite is provided with a first magnetic torquer mounted on an X axis, a second magnetic torquer mounted on a Y axis and a reaction wheel mounted on a Z axis. The method comprises the steps of obtaining an expected control moment based on an angular velocity error, an attitude angle error and a preset angular velocity threshold value of a satellite; according to the working state and the expected control torque of the reaction wheel, a first magnetic moment instruction of the first magnetic torquer and a second magnetic moment instruction of the second magnetic torquer are adjusted, and a control torque instruction of the reaction wheel is adjusted, so that the attitude of the satellite is controlled. By applying the technical scheme provided by the embodiment of the invention, the structural thickness of the satellite in the opposite direction can be reduced, and the satellite launching cost is reduced.
