基于北斗三号和天通卫星通信的信道收发模块设计与实现

Design and realization of channel transcevier module based on Beidou 3 and Tiantong satellite communication

如今战争信息化迅猛发展,卫星通信极大地解决了通信距离短的问题,而且多数情况下只需要手持便携终端即可通信。我国天通通信卫星和北斗三号卫星均在不久前已经组网,覆盖了我国甚至全球,可满足语音、短报文等通信需求。但是目前的终端只实现了天通或者北斗等单一的模式,或者需要两种主机来实现车载和车下两种应用场景。因此,文章设计了一种基于北斗三号和天通卫星通信的信道收发模块,解决了只能实现单一模式卫星通信的问题,可以实现北斗三号、北斗二号和天通多模式通信,同时也解决了车上放置和车下便携等多场景应用模式。

Nowadays,with the rapid development of war informatization,satellite communication greatly solves the problem of short communication distance,and in most cases only need handheld terminals to communicate. China’s Tiantong communication satellite and Beidou 3 satellite have been networked not long ago,covering China and even the world,and realizing communication needs such as voice and short message. However,the current terminal only realizes the single mode of Tiantong or Beidou,or requires two hosts to realize the two application scenarios of on-board and off-car. Therefore,this paper designs a channel transcevier module based on Beidou 3 and Tiantong satellite communication,which solves the problem of only realizing single mode satellite communication,and can realize the multi-mode communication of Beidou 3,Beidou 2 and Tiantong. At the same time,it also solves the multi-scene application modes such as on-car placement and off-car portability.
