“Google Loon”高空超压气球网络技术综述

Study on Google Loon High-Altitude Super Pressure Balloon Network Project

Google公司推出的"Google Loon"气球网络项目,用漂浮的高空气球作为通讯中继实现地面互联网的覆盖。重点介绍了基于高空超压气球的气球网络原理、Loon超压气球组成结构及各组成部分的作用及性能,分析了"Google Loon"高空超压气球的轨迹控制、高度调节、充气及发射等关键技术。最后,对Loon项目的试验历程和商业推广情况进行了回顾,并对未来工作计划进行了展望。

The ＂Google Loon＂ network project launched by Google employs high-altitude super pressure balloons as the communication replay platform so as to cover the earth with the Internet. The paper mainly introduces the network principle of high-altitude super pressure balloons, composition and structure of Loon super pressure balloons, and the role and performance of each component, analyzes its key technologies such as trajectory control,altitude control, inflation and launch,and finally reviews the experimental course and commercial promotion of the Loon project and also forecasts the future working plan.
