Size and weight limitations of low‐Earth orbit (LEO) small satellites make their operation rest on a fine balance between solar power infeed and power demands of supporting communication technologies, buffered by on‐board battery storage. As a result, the problem of planning battery‐powered intersatellite communication is a very difficult one. Nevertheless, there is a growing trend toward constellations and mega‐constellations that are to be managed using sophisticated software support. In earlier work, we have discussed how the effective construction of contact plans in delay‐tolerant satellite networking can profit from a refined model of the on‐board battery behavior. This paper presents a profound study of the scalability of the approach and discusses how to tailor it to the needs arising in the management of mega‐constellations, together with a variety of improvements to the base approach. Results show that efficient mega‐constellation operations are compromised, encouraging further research on the area.

关于LEO卫星星座电池感知联系计划设计的可扩展性

低地球轨道(LEO)小卫星的大小和重量限制使其运行在太阳能馈电和支持通信技术的电力需求之间达到良好的平衡,并通过车载电池存储加以缓冲。结果,规划电池供电的星际通信问题非常困难。尽管如此,使用高级软件支持来管理星座和巨型星座的趋势正在增长。在较早的工作中,我们讨论了在延迟容忍的卫星网络中有效建立联系计划的方式如何从机载电池行为的精确模型中获利。本文对这种方法的可扩展性进行了深入的研究,并讨论了如何针对大型星座管理中出现的需求量身定制该方法,以及对基本方法的各种改进。结果表明,大型星座的有效运行受到了损害,这鼓励了对该地区的进一步研究。
