| Abstract: | Although space electronic units are fully tested and experimented on ground, unexpected fault still exists. Reliability, safety and flexibility of these products can be improved by repairing the FPGA-based hardware system on orbit. Based on the in system pro- gramming （ISP） technique, a scheme for repairing FPGA-based hardware system is proposed. An imple- mentation for the scheme is introduced using an exam- ple and a proposal is also provided. |
