                                                                                                                                                                          我国新一代海洋综合科考船“科学”号在完成2018年第6次西太平洋综合考察航次后,昨天(1月31日)返回位于青岛西海岸新区的母港。我国科学家在本航次成功维护升级了我国的西太平洋实时科学观测网,实现了多项重大突破。

                                                                                                                                                                          本航次的重大突破是首次实现了深海潜标大容量数据的北斗卫星实时传输。该项自主研发的技术成果克服了深海潜标载荷容积小、供电少和数据量大等困难,改变了以往依赖国外通信卫星的历史,显著提高了深海数据实时传输的安全性、自主性和可靠性。

                                                                                                                                                                          本航次历时74天,航程12000余海里,这是科学号首航以来离开国内航程最长、时间最长的一个航次。观测网内的20套深海潜标、4套大型浮标共千余件观测设备,已经稳定获取连续4至5年的观测数据。

                                                                                                                                                                          中国北斗三号基本系统完成建设 开始提供全球服务

                                                                                                                                                                          去年12月27日,中国卫星导航系统管理办公室主任、北斗卫星导航系统新闻发言人冉承其宣布:北斗三号基本系统完成建设,于今日开始提供全球服务。这标志着北斗系统服务范围由区域扩展为全球,北斗系统正式迈入全球时代。
