Dense small satellite networks (DSSN) in low earth orbits (LEO) can benefit several mobile terrestrial communication systems (MTCS). However, the potential benefits can only be achieved through careful consideration of DSSN infrastructure and identification of suitable DSSN technologies. In this paper, we discuss several components of DSSN infrastructure including satellite formations, orbital paths, inter-satellite communication (ISC) links, and communication architectures for data delivery from source to destination. We also review important technologies for DSSN as well as the challenges involved in the use of these technologies in DSSN. Several open research directions to enhance the benefits of DSSN for MTCS are also identified in the paper. A case study showing the integration benefits of DSSN in MTCS is also included.

适用于现代地面通信系统的密集小型卫星网络：收益，基础设施和技术

低地球轨道（LEO）中的密集小型卫星网络（DSSN）可以使几种移动地面通信系统（MTCS）受益。但是，只有仔细考虑DSSN基础结构并确定合适的DSSN技术，才能实现潜在的利益。在本文中，我们讨论了DSSN基础架构的几个组成部分，包括卫星编队，轨道路径，卫星间通信（ISC）链接以及用于从源到目标的数据传递的通信体系结构。我们还将回顾DSSN的重要技术，以及在DSSN中使用这些技术所涉及的挑战。本文还确定了一些开放的研究方向，以增强DSSN对MTCS的好处。还包括一个案例研究，显示了DSSN在MTCS中的集成优势。
