Abstract

Satellites have been around for many decades, yet the low Earth orbit (LEO) was avoided as the cost exceeded the demand until recently. This paper is based on a live presentation to the Australian Telecommunications Association (TelSoc) by Ruth Pritchard-Kelly, Senior Advisor on Regulatory Affairs for OneWeb, and was chaired by TelSoc Broadband Futures Group member, John Costa. This paper describes the new generation of LEO satellites, how they substantially differ from earlier satellites, and the factors now making them not only viable but increasingly indispensable as part of a global communication ecosystem. The paper then introduces OneWeb’s specific LEO plans, including details about deployment in Australia.

低地球轨道卫星系统

卫星已经存在了几十年，但直到最近，由于成本超过需求，低地球轨道(LEO)才被避免。本文基于OneWeb监管事务高级顾问Ruth Pritchard-Kelly对澳大利亚电信协会(TelSoc)的现场演讲，并由TelSoc宽带未来小组成员John Costa主持。本文描述了新一代LEO卫星，它们与早期卫星的本质区别，以及现在使它们不仅可行而且越来越不可或缺的因素作为全球通信生态系统的一部分。然后介绍了OneWeb的具体LEO计划，包括在澳大利亚部署的细节。
