Credible test of attitude and orbit control system

Credible ground test of spacecraft attitude and orbit control system become very important since modern spacecrafts are complex and the performance requirements are higher. However, the theories and technologies of credible test of spacecraft control systems are not researched thoroughly. For engineering applications, we present the definition and factors of test credibility, and introduce a procedure of credible test of spacecraft control system. Furthermore, we discuss the technologies of flexible prototype test, high credibility modeling of dynamics, accurate and real-time sampling, credible signal resource design, etc.
