基于有线连接的天通卫星背夹的设计与实现

Design and Implementation of Tiantong Satellite Mobile Phone Sleeve Based on Wired Connection

阐述基于有线连接的方式设计天通卫星背夹用于拓展通信终端的卫星功能,利用通信终端现有的物理接口作为与背夹之间的数据和指令的传输通道,并通过开发的安装在通信终端上的卫星应用软件,实现天通卫星的电话拨打和短信的收发。测试验证表明,背夹实现了终端卫星通信功能的拓展,具有携带方便、使用便捷的特点,有较高的推广应用价值。

This paper describes the design of the Tiantong satellite back clip based on wired connection to expand the satellite function of communication terminals.The existing physical interface of the communication terminal is used as the transmission channel for data and instructions between the back clip and the communication terminal.Through the development of satellite application software installed on the communication terminal,the Tiantong satellite achieves telephone calls and SMS transmission.Test verification shows that the back clip has expanded the terminal satellite communication function,and has the characteristics of convenient carrying and use,with high promotion and application value.
