Abstract

A global navigation satellite system (GNSS) buoy system for early tsunami warnings has been developed for more than 20 years. The first GNSS buoy system using a real-time kinematic algorithm (RTK) was implemented in the Nationwide Ocean Wave information network for Ports and HArbourS (NOWPHAS) wave monitoring system in Japan in 2008. The records of NOWPHAS were used to update the tsunami alert by the Japan Meteorological Agency (JMA), owing to the tsunami generated by the 2011 Tohoku-oki earthquake (Mw9.0). However, considering that the distance limit is less than 20 km for the RTK algorithm, a new system was designed by introducing a new positioning algorithm and satellite data transmission to place the buoy much farther from the coast. A new technique for the continuous monitoring of ocean-bottom crustal movements was also implemented in the new system. The new buoy system can be used for weather forecasting and ionospheric monitoring as well.

地质灾害综合监测系统GNSS浮标研制。

全球导航卫星系统(GNSS)海啸早期预警浮标系统已经发展了20多年。2008年，第一个使用实时运动学算法(RTK)的GNSS浮标系统在日本全国港口海浪信息网络(NOWPHAS)海浪监测系统中实施。由于2011年东北大地震(Mw9.0)引发海啸，日本气象厅(JMA)利用NOWPHAS的记录更新海啸警报。然而，考虑到RTK算法的距离限制在20公里以内，我们设计了一个新的系统，通过引入新的定位算法和卫星数据传输，将浮标放置在离海岸更远的地方。新系统还实现了海底地壳运动连续监测的新技术。新的浮标系统也可用于天气预报和电离层监测。
