Abstract
In recent years, with the deployment and application of LEO microsatellite constellations, microsatellite has entered the development stage of “blowout”. How to further improve the performance of the microsatellite electronic system, the utilization rate and reliability of computing resources, reduce its cost and volume and weight has become one of the key problems in the design of a microsatellite electronic system. Based on COTS (Commercial-Off-The-Shelf), an integrated platform of on-board computer and star sensor electronics system is designed in this paper. The platform adopts heterogeneous multiprocessor architecture, which makes up for the low reliability of commercial devices. Its comprehensive computing capacity can reach 14000MIPS, compared with the general space antiradiation processing platform, its performance is improved by 10~100 times. The reliability analysis shows that the reliability of the platform is not less than 0.9999 in three years.
