摘要浮标是目前对海洋波浪进行长期、实时、定点观测的主要设备,发展波浪浮标是发展海洋观测的必然需求。针对实际波浪测量是在远离大陆的海洋深处进行的,本文采用基于GPS精密单点定位方法求取海水面高度变化,进行浪潮分离获取波浪高度变化序列,并用频谱分析的方法获取波浪参数。经海上实测验证的结果可知,本方法获取的波浪要素精度与测波仪所得结果精度相当,两者平均波高偏差约4cm,。

Abstract:Buoy is the main equipment of observation on the ocean wave for long-term, real-time, fixed- development of the wave buoy is the inevitable demand for the development of ocean on the actual work conditions that our measurement is far away from the mainland and located in the depths of the ocean, this paper based on the theory of Precise Point Positioning (PPP) to get the height changes in the sea surface. Then we can separate the wave from the sea-surface height changes to obtain the wave displacement, and the wave parameters are obtained by the spectral verified results of wave measurement shows that it has equivalent accuracy with the results obtained by the wave gauge, and the mean wave height differential is close to 4cm, the mean wave period differential is .
Key words:GPS precise point positioning,wave measurement,
