摘要
近年来,小卫星的数量正迅猛增长。面对众多庞大的小卫星星座,小卫星系统应建立起专用的测控通信网。目前,国外的小卫星测控通信网具有自主性和简易性的特点,发展较为成熟。介绍了国外小卫星使用的几种典型测控通信网,包括美国航空航天局(NASA)的空间通信与导航网(SCaN)、美国行星实验室的"鸽子"卫星测控网以及欧空局的卫星操作全球教育网(GENSO),提炼了关键技术,总结了小卫星测控通信网的未来发展趋势,以期为中国小卫星测控通信网的建设提供参考。
In recent years,the number of small satellites is booming.Faced with so many large small satellite constellations,a specialized Tracking Telemetry&Command(TT&C)and communication network for small satellites should be established.At present,foreign TT&C and communication networks for small satellites feature autonomy and simplicity,and have become fu ll-fledged.This paper introduces several typical foreign TT&C and communication networks for small satellites are introduced,including NASArs Space Communications and Navigation(SCaN),U.S.Planet Labs'Dove satellites TT&C communication network and ESA^s Global Educational Network for Satellite Operations(GENSO).Then,it extracts the key technologies,and summarizes the trends of TT&C and communication networks for small satellites in hope of providing reference for the establishment of China's small satellites'TT&C and communication network.
