Bus saturation is deemed as one of the primary causes of delays in the data propagation between spacecraft components. However, the conditions under which bus congestion can affect measurements variability were not well characterized before. This paper presents a bus saturation model and a set of experiments to characterize the bus performance of satellite missions for different traffic load, data rate, and synchronization periods. The results showed an increase of measurements variance of up to 18% caused by bus saturation. Additionally, an algorithm was proposed to reduce the data delay by controlling the saturation on the communication channel at the operational level.

饱和对高吞吐量卫星总线的影响

总线饱和被认为是导致航天器组件之间数据传播延迟的主要原因之一。然而，公交车拥堵会影响测量变异性的条件以前没有得到很好的表征。本文提出了一个总线饱和模型和一组实验来表征卫星任务在不同流量负载、数据速率和同步周期下的总线性能。结果表明，由于总线饱和，测量方差增加了 18%。此外，还提出了一种通过在操作级别控制通信信道上的饱和来减少数据延迟的算法。
