Abstract

Space missions are very demanding on system reliability. As the development of space-based remote sensor technologies, space missions are increasingly high required on system performance. Conventional techniques mainly focus on the system reliability, at the expense of system performance.

In this paper, a flexible, DPS-based, high-performance system is presented. The system could dynamically adapt the system’s level of redundancy according to varying radiation levels. A compare-point and fast recovery mechanism is proposed to improve system performance. Besides, some design ideas and implementation methods also be mentioned. In this paper, the system performances are evaluated and analyzed. With running of the correlation function benchmark in this system, it is shown that the system provides high performances under the premise of certified reliability.
