This special issue of the journal on ‘constellations’ comes at a critical time in their development as a second wave of such non‐geostationary satellite orbit (NGSO) systems is being planned and deployed. These mega‐constellations as they have become known are, with a few exceptions, very much larger than those in the first wave and are focused on broadband and 5G applications rather than speech and narrow band data as those deployed in the first wave during the 1990s. However, as we explain in this editorial, there are many similarities in the design and business plans to the first wave and, perhaps, many similar lessons to be learned.

非对地静止卫星轨道通信卫星星座史

这本关于“星座”杂志的特刊正值其发展的关键时刻,因为正在计划和部署第二波此类非对地静止卫星轨道(NGSO)系统。除少数例外,这些已广为人知的巨型星座比第一波大得多,它们集中于宽带和5G应用,而不是像1990年代第一波中那样部署的语音和窄带数据。但是,正如我们在这篇社论中所解释的那样,设计和商业计划与第一波有很多相似之处,也许还有许多相似的教训需要学习。
