A new tsunami observation system has been developed, which employs the GPS technology to detect a tsunami before it reaches the coast. After a series of preliminary experimental studies, the GPS buoy system is employed along the Pacific coast and Japan sea coast.Currently, the GPS buoy system uses RTK (Real Time Kinematic) method which requires land base for precise positioning of the buoy. This limits the distance of the buoy from the coast at most 20km. There are two problems to be conquered, one is the precise GPS positioning and the other is the data transmission methods. The algorithm of PVD (Point precise Variance Detection) method and PPP-AR (Precise Point Positioning with Ambiguity Resolution) method are successfully under examination in the Muroto GPS buoy. Also, the satellite communication system using QZSS (Quasi-Zenith Satellite System) and ETS-VIII (Engineering Test Satellite VIII) were introduced for this GPS tsunami observation system experimentally.

一种新的海啸观测系统已经开发出来，它利用GPS技术在海啸到达海岸之前进行探测。经过一系列初步的实验研究，在太平洋沿岸和日本海沿岸采用了GPS浮标系统。目前，GPS浮标系统采用RTK （Real Time Kinematic）方法，需要陆上基地对浮标进行精确定位。这将浮标与海岸的距离限制在最多20公里。有两个问题需要克服，一是精确的GPS定位，二是数据传输方式。在Muroto GPS浮标中，成功地对PVD（点精确方差检测）算法和PPP-AR（模糊分辨率精确点定位）算法进行了测试。同时，介绍了准天顶卫星系统（QZSS）和工程试验卫星（ETS-VIII）在该GPS海啸观测系统中的通信系统。
