A Novel Communication and Navigation Method for Ocean Data Buoy's Observation System

提出了利用中国区域定位系统(Chinese Area Positioning System,CAPS)和CAPS终端开展海洋资料浮标通讯和导航的一种新方法。根据海洋资料浮标发送数据量大而接收数据量小的特点,创新性地提出利用复合导航电文的方法,将通信地面站出站发送给通信卫星转发改为导航系统下行转发,将CAPS终端通信部分接收改为导航定位部分接收,成功地把CAPS终端发展到CAPS-OC(Chinese Area Positioning System-Ocean Communication,CAPS-OC)终端。海上实验表明CAPS-OC终端及CAPS系统可以满足各种海洋资料浮标的通讯和导航定位的功能要求,目前有两台CAPS-OC终端已经成功地应用在浅海大型锚系浮标观测系统的数据传输中。

A novel communication and navigation method for ocean data buoy＇ s observation system using CAPS and CAPS terminal was put forward. According to the quantity of transmission data is much bigger than the receiving data, the complex navigation data method had been utilized. And CAPS terminal was successfully developed to CAPS-OC terminal with some alternations, such as navigation system transmitting data in down-link substituted for communication station transmitting data to communication satellite, changing receiving data module from communication module to navigation module. The ocean experiment showed that CAPS-OC terminal and CAPS could meet the communication and navigation requirement of all kinds of ocean data buoy＇ s. At present two CAPS-OC terminals have been used on shallow sea large mooring buoy＇s observation system.
