直播卫星终端双星接收方案研究与验证

Research and Verification of DTH Terminal Simultaneous Receiving for Live Broadcasting Satellite Terminal

我国现有两颗在轨直播卫星,分别是中星9号和中星9B。传统直播卫星接收方式仅能接收其中一颗的信号,一定程度上造成了宝贵卫星带宽资源的浪费。本文设计了一种同时接收两颗直播卫星的接收方式,并通过实验验证了可行性。本文主要从双星接收数据测算、终端功能优化升级及实地验证三方面进行了阐述。

There are currently two DTH satellites in orbit in China,namely ChinaSat 9 and ChinaSat 9B.The traditional DTH satellite reception method can only receive the signals from one of them,which to a certain extent causes the waste of valuable satellite bandwidth resources.This paper designs a reception method to receive two DTH satellites simultaneously,and verifies the feasibility through experiments.This paper focuses on three aspects:two sat simultaneous reception data measurement,optimization and upgrading of terminal functions,and on-site verification.
