Space vehicles need to maintain continuous and stable operation in the complex and changeable space environment years. In order to adapt to the complex space environment and complement exploration, positioning, communication and other tasks in space, spaceborne electricity uses SOC as the main control chip to switch software version, update the ground injection and correct the software program error and other software dynamic deployment technology, to achieve the system software reconstruction function. This function can be a good solution on the satellite requirements of dynamic update of payload working parameters can solve the needs of different flight missions or different stages of missions. The system flexibility and reliability are improved by using different working modes.
