  • Online:2024-12-26 Published:2025-01-07

Abstract: Chang’e-6 successfully completes the world’s first sampling and takeoff on the far side of the moon, opening a new chapter of lunar science. The reliability of control software plays an extremely important role in the reliable operation of the entire aircraft system. This article elaborates on the key points of software reliability design of the control system, considering the practical characteristics of the software system for the Chang’e-6 spacecraft. Describe the reliability design method of the Chang’e-6 control software from two perspectives: program reliability design and data reliability design. Apply error avoidance, error checking and fault-tolerant in software reliability design, propose a software synchronization and recovery method that combines time, data and events. Using the software reliability design described above will help improve the reliability of aerospace control software and ensure the success of space missions.

Key words: Chang’e-6, control software, software design, reliability design
