The integrated spaceborne computer adopts a multi-functional and highly integrated design, integrating orbit positioning, attitude measurement, attitude control, calculation, storage and other functions. The overall volume is 200*100*21mm and the weight is less than 600g. It replaces the traditional satellite reaction flywheel control board, magnetic torque control board, magnetometer, gyroscope, and power distribution board.
