The invention relates to an attitude and orbit control micro-thruster. Comprising a shell, a main gas circuit board, a side gas circuit board I, a side gas circuit board II, a gas circuit block, a storage tank, an attitude control valve, an orbit control valve, a pressure reducing valve and a piezoelectric proportional pilot valve. The gas path block is in a cross-like shape, the upper part of the gas path block is connected with the main gas path plate, the lower part of the gas path block is connected with the storage tank, and the side gas path plate I and the side gas path plate II are diagonally arranged on the side surface of the gas path block and are connected with the main gas path plate; two side plates of the side gas circuit plate I are respectively connected with a piezoelectric valve, and the four piezoelectric valves form an attitude control valve; the four cross-shaped side faces of the gas circuit block are each connected with an electromagnetic valve, the distribution plane of the four electromagnetic valves is perpendicular to the main axis of the storage tank, the upper surface of the gas circuit block is connected with an electromagnetic valve installed on the main axis of the storage tank, and the five electromagnetic valves form an orbit control valve. And the pressure reducing valve and the piezoelectric proportional pilot valve are both connected with the gas path block. Thrust can be generated in multiple directions in the space, attitude and orbit control is completed, the structure is simple, installation is easy, and work is reliable.
