摘　　要：在星务管理系统软件的设计开发中,为了更好地满足系统的高实时性、高安全性、高可靠性等要求,提出采用实时性强的操作系统——VxWorks操作系统作为卫星星务系统的核心。采用VxWorks操作系统的多任务调度机制,并结合基于时间片轮转调度实现多任务设计算法的特点,进而制定出星务管理系统软件的架构。结果表明,该设计满足卫星星务系统软件设计的可靠性、实时性的要求。In the process of the design and development of star management system software, in order to satisfy the requirements of high real-time performance, high security and high reliability, this paper proposes a real-time operating system VxWorks operating system as the core of the satellite service system. VxWorks operating system employs the multi-task scheduling mechanism, com-bined with the method of calculation based on the round robin scheduling, moreover, developing the architecture of star manage-ment system. The results manifests that in the premise of fulfilling the satellite on-board system software design requirements, the real-time performance is improved.
