| 摘 要： | 高级在轨系统（AOS）体制的核心是调度策略,文章针对我国航天器遥测数据及信道特点,提出了一种高效的AOS遥测源包调度算法,该算法基于优先级调度,对各种数据可以设计不同的优先级,在调度时满足了低速数据的传送要求以及突发数据等高实时性的要求,尤其是信道空闲时算法在优先调度高优先级源包的同时,也兼顾了低优先级源包的下传需求。...

| Abstract: | Scheduling strategy is the key of CCSDS AOS telemetry scheme.Based on the CCSDS AOS packet telemetry standard and the characteristics of the spacecraft telemetry data,an efficient priority scheduling algorithm is designed in this paper.By providing different priorities for different AOS packets,the priority scheduling algorithm is a mechanism which can be used to meet the requirements of both the low-speed data transfer and the unpredictable emerging real-time data transfer.More importantly,low priority pac... |
