摘要
中星16号卫星是我国首颗Ka频段大容量多媒体通信卫星,预计2017年初发射。应用点波束和频率复用技术,Ka频段高吞吐量卫星(HTS)通信系统支持更高速率的互联网接入,更复杂的交互式服务;相应地,其配套地面系统的架构和能力也需要进行提升。本文从Ka频段卫星系统组成、影响地面系统选址的几个主要因素、Ka频段与其他常用卫星频段的区别等方面进行分析,总结选址原则,将会为各行各业的用户提供更加灵活、更高成本效益的卫星宽带通信服务打下基础。
The No.16 satellite is China＇s first large-capacity and Ka-band multimedia communication satellite,expected to be launched in early 2017.Adapting spot beam and frequency reuse technology,Ka- band high throughput satellite（HTS）communication systems supports higher speed Internet access,more complex interaction service,and accordingly,architecture and capacity of its terrestrial systems also need to be improved.This paper,from perspective of Ka-band satellite systems composing,several major factors that influence the terrestrial systems siting,difference between Ka- bandand and other normal satellite bands,analysis and summarized siting principles,will provide more flexible,higher cost- gain satellite wide band communication service.
