摘要

KA-SAT于2010年12月发射,是当前一代高通量卫星(HTS)中的第一颗。系统总容量超过90Gbit/s,可支持多达100万用户,可提供与地面ADSL2+类似的服务。为了满足对容量和设备日益增长的需求,预计TWTA的带宽将需要覆盖2.9GHz。我们将讨论KA-SAT中采用的技术以及预计它将引领我们走向何方。

KA-SAT and future HTS systems
Launched in December 2010 KA-SAT represents the first of the current generation of High Throughput Satellites (HTS). With a total system capacity of over 90Gbit/s and the capability of supporting up to a million users, it delivers services akin to those provided by terrestrial ADSL2+. In order to meet increasing demands on capacity, and subsequently on equipment, it is expected that the bandwidth of the TWTA will need to cover 2.9GHz. We discuss the technology employed in KA-SAT and where it is anticipated it will lead us.
