The invention provides a satellite on-orbit digital baseband platform. The satellite on-orbit digital baseband platform comprises a main control unit, a plurality of satellite control units, at least one first nonvolatile storage unit and at least one second nonvolatile storage unit, the first nonvolatile storage unit is used for storing an original program for controlling the satellite control chip unit to run; the satellite control unit is used for executing a satellite on-orbit task; and the main control unit is used for receiving a reconfiguration program of the original program sent by the ground station, writing the reconfiguration program into the second nonvolatile storage unit, controlling the satellite control unit to restart, and loading the reconfiguration program stored in the second nonvolatile storage unit to control the satellite control unit to work so as to realize satellite on-orbit reconfiguration.

    本申请提供一种卫星在轨数字基带平台,包括:主控单元、多个卫星控制单元、至少一个第一非易失性存储单元、至少一个第二非易失性存储单元;第一非易失性存储单元,用于存储控制卫星控制芯片单元运行的原始程序;卫星控制单元,用于执行卫星在轨任务;主控单元,用于接收地面站发送的对于原始程序的重构程序,将重构程序写入第二非易失性存储单元,以及控制卫星控制单元重新启动,并加载第二非易失性存储单元存储的重构程序控制卫星控制单元工作,实现卫星在轨重构。
