Abstract

This work addresses the dual-node hot-standby requirement of the space TT&C (Telemetry, Tracking, and Control) mission computer system by designing the architecture and functions of a duplex management software system. It provides a detailed specification of key workflows, including status monitoring and switchover control, and supports various deployment requirements on both physical hosts and virtual machines. By leveraging the Linux system call mechanism, a runtime optimization strategy is proposed. Test validation shows that this strategy reduces the worst-case end-to-end latency of heartbeat signal transmission and reception to less than 10 ms. This ensures low-latency state synchronization and the efficient and stable operation in complex environments, providing reliable assurance for the execution of measurement and control tasks.

Keywords
