Research on the Quality Assurance Method of Spacecraft Software Based on Software Testing

Abstract

Aerospace technology is the most important symbol of the national strength, the national defense and the comprehensive national strength. With the change of times and the development of information technology, the development trend of the Spacecraft is more serialized, more intelligent and more precise. The computer systems are becoming more and more widespread in the spacecraft system. Aerospace engineering is an system which is huge, complicated and high technical difficulty. In this system, the computer and the software play an important role about the system control, process control, data acquisition and processing, data communication and system security and other tasks. The software has become the nerve center of the whole system, and it produces all kinds of information to make the other part of the system perform corresponding actions. The spacecraft software is bigger and bigger, the structure is more and more complex, and the requirement for software quality is higher. This paper investigates and studies the major software quality accidents and its causes. Base on the software test, this paper put forwards the method of software quality assurance and the construction idea of software evaluation Organization. The method proposed in this paper has been applied in several spacecraft, and the results show that the reliability and safety of the software can be effectively improved, and the quality of the spacecraft is guaranteed.
