Spacecraft testing is an important phase of developing a spacecraft. As the test task requests in spacecraft testing have dynamic, real-time and resource constraints characteristics, it need further research on requests scheduling policy. Based on the EDF scheduling model, this study apprehends the dynamic, real timing and communicating resource limitation in automated testing of application-level device gateway in spacecraft subsystem in its design of a multiple-factor based PRI ascertain method and put forward a scheduling policy of multithreading under resource limitation. Test results show that this policy better assures scheduling effect with effectivescheduling of each parallel testing task under different task densities.
Key words: Automated testing, EDF, spacecraft testing, real-time task scheduling, , ,
