天津59(新华社)——地方当局周五说:中国独立研发的北斗导航卫星系统取得了亚米级定位精度,并且在海洋应用上取得重大突破。    
北斗无线差分信号的北斗导航卫星系统(RBN-DBDS)通过基站接受发送信号差分计算中频无线电波 (285 - 325千赫)来改善定位精度,是类似GPS的一种增强系统。RBN-DBDS系统在天津市通过了一项超过130天的评估测试试验。它可以应用在航海、海洋勘探和救援,和海上图表和监控。系统完成后,客户可以免费享受北斗与双模和GPS接收机定位服务。
TIANJIN, May 9 (Xinhua) -- China's independently-developed Beidou differential navigation satellite system has achieved a positioning accuracy within one meter, a major breakthrough in marine application, local authorities said Friday.
The Beidou Radio Beacon-Differential Beidou Navigation Satellite System (RBN-DBDS) is an augmentation system that provides improved positioning accuracy of the GPS-like Beidou Navigation Satellite System by broadcasting differential corrections to Beidou receivers in the medium frequency radio beacon band (285-325 khz).

The RBN-DBDS system has passed an evaluation after more than 130 days of test trials in Tianjin Municipality. It can be applied in sailing, marine exploration and rescue, and maritime charting and monitoring.
After the system's completion, customers can receive free positioning services from Beidou and GPS with a dual-mode receiver.
