| Abstract: | In view of the long time-consuming and poor reconstruction performance of traditional unmanned spacecraft software reconstruction technology , a CPCI module-based unmanned spacecraft software reconstruction technology is proposed．All the interfaces of the bus in the CPCI module are called to control the dynamic loading sequence of the modules to realize the dynamic loading of the CPCI module ; VI program configuration and FPGA VI subprogram configuration are used to complete the calibration development of the unmanned spacecraft ’s position , and the timing execution is configured through FPGA Important instructions such as ignition , flame spraying ,driving , and flameout．Multiple AD acquisition boards are integrated to complete the software programming program , start each interface in the CPCI module ,complete the dynamic configuration of the module , and realize software reconstruction．The experimental results show that the reconstruction of the unmanned spacecraft software reconstruction technology based on the dynamic loading of the CPCI module takes a short time , the operating effective power is high , and the motor speed is stable． |
