The invention is applied to the technical field of aerospace, and particularly discloses a satellite attitude and orbit integrated control device for step-length control thrusters, the satellite attitude and orbit integrated control device comprises a body, the mass center coordinate system of the body is 0-XYZ, a third thruster and a fourth thruster are rotatably mounted on the XOZ face of the body, a rotating meshing mechanism is arranged on the outer surface of the body, and the third thruster and the fourth thruster are meshed with each other through the rotating meshing mechanism. The posture of the body can be accurately adjusted by rotating the meshing mechanism. According to the satellite attitude and orbit integrated control device for controlling the thruster through the step length, when the body needs to be subjected to orbit adjustment, a nozzle in a certain axial direction is adjusted, so that the thrust direction of the nozzle is perpendicular to the axial direction of the advancing direction, the speed is provided, and orbit transfer is conducted according to the Kepler law; when the satellite needs to be subjected to attitude adjustment around a certain axis, the nozzles are adjusted to be parallel to the bottom surface, the two engines on the same plane are started to generate torque, the satellite is made to roll to adjust the attitude, and when the body needs attitude and orbit control, the engine step length can be adjusted to control thrust working time adjustment.
