Space vehicles need to maintain continuous and stable operation in the complex and changeable space environmentyears. In order to adapt to the complex space environment and complement exploration, positioning, communication and other tasksin space, spaceborne electricity uses System on Chip (SOC) as the main control chip to switch software version, update the groundinjection and correct the software program error and other software dynamic deployment technology, to achieve the system softwarereconstruction function. This function can be a good solution on the satellite requirements of dynamic update of payload workingparameters can solve the needs of different flight missions or different stages of missions. The system flexibility and reliability areimproved by using different working modes.
