北斗远程通信船载终端



                                           系统介绍
 
                                                    系统包括舱外单元和舱内单元,采用自主开发的微弱信号处理技术,自适应动态增益调节处理和全自动跟踪技术集成
                                              10°E -145 °W | 50°S-75°N范围内的定位、测速、短报文通信服务功能。支持手机、电脑等终端设备基于北斗的短消息
                                              语音、图像等传输,为用户提供便捷、准确的北斗定位通信服务。在准全球范围内,为用户提供移动卫星通信服务。
 
                                                     系统优势
 
                                              ■超远程通信
                                                 利用北斗系统实现跨洲际通信为用户提供超远程通信手段。
                                              ■微弱信号处理
                                                 通过微弱信号处理技术使得在北斗弱信号条件下仍能实现北斗信号的正常接收。
                                              ■辅助天线快速对准
                                                 终端根据所在位置及选择的卫星波束,自动计算收发天线的俯仰及方位角。将天线快速对准卫星完成终端使用部署。
