The invention discloses a micro-cathode arc thrust array system, and relates to the technical field of satellite micro-propulsion. The system comprises a thruster integration part, a power output unitand a control part, wherein the thruster integration part is formed by arranging and integrating a plurality of groups of micro-cathode arc thrusters according to an even regular polygon placement mode; the output end of the power output unit is connected with the anode of the thruster integration part through the control part, and the cathode of the thruster integration part is connected with the input end of the power output unit; cathodes of the multiple sets of micro-cathode arc thrusters are shared. On-off between different anodes and cathodes of the thruster integration part is controlled through the control part, so that the purpose that the multiple sets of micro-cathode arc thrusters discharge in turn is achieved. By changing the discharge mode of the control part, the micro-cathode arc thruster can be selected from multiple working modes, and the purpose of meeting different propulsion requirements is achieved. The system has the functions of reducing the mass and the volume, increasing the thrust-weight ratio and the reliability, better meeting the satellite propulsion requirement and the like.
