基于浮标平台的卫星通信优化设计

Optimal Design of Satellite Communication Based On Buoy Platform

卫星通信是基于视距的通信方式，要求通信时射频信号可以发射到卫星转发器上。因此，要求卫星通信终端在工作时天线对准卫星或者使用全向天线。浮标通信平台具有不稳定的特点，在海况不好的时候，通信平台的摇晃幅度非常大，虽然多采用全向天线，但常常出现数据传输中断，影响用户的使用。本设计在常规浮标卫星通信方案的基础上，采用类卫星接收机的模块，增加卫星信号强度检测功能，合理选择卫星通信时机，可以利用水面的摇摆特点，化不利因素为有利因素，大大降低浮标平台卫星通信数据传输的丢包率。

Satellite communication is a communication method based on sight range. The RF signal is required to be sent to the satellite transmitter while communicating. Therefore, the antenna has to aim at the satellite or the omnidirectional antenna is used while satellite communication terminal is working. Due to its unstable feature, the buoy platform swings greatly in severe sea condition, and data transmission is often interrupted although the omnidirectional antenna is used. In this paper, based on the conventional buoy satellite communication scheme, we select module of satellite receiver to enhance the test function of satellite signal, and reduce the packet loss rate of data transmission in buoy platform satellite communication by using the feature of water swinging.
