AbstractOnboard data handling (OBDH) system is the key to spacecraft avionics. To adapt to the harsh external space environment, traditional onboard data handling system is usually highly expensive, complex and arduous by using high quality components. Design of a compact and reconfigurable onboard data handling system based is proposed in this paper. A NOR Flash with mass storage is designed as the program memory for CPU and SRAM FPGAs. The programs of the CPU and SRAM FPGAs in this system can still be reconfigurable for the launched satellites. Rad-hard designs from the Software and hardware are adopted in the onboard data handling system to realize the performances of high reliability, anti-SEU(single event upset) effect, software reconfiguration with less mass, volume and cost. Some experimental results are shown at last in the system verification.
