| Wave observation plays an important role in Marine environment forecast, Marine engineering construction, Marine resources investigation and navigation safety. The method of wave observation based on GNSS (Global Navigation Satellite System) buoys has many advantages such as all-weather, real-time, high accuracy and low price. Meanwhile, other marine environment measuring instruments can be integrated on the buoys, so it has attracted more and more attention from researchers around the world. This paper presents a wave parameter inversion method based on GNSS buoy, and successfully applied in Wenzhou, Zhejiang. In the process of sea trials, with acknowledged wave rider buoy contrast, the average wave high correlation coefficient is 0.95, and the standard deviation is 4.06 cm. The correlation coefficient of 0.92, and the standard deviation is 0.24 s, completely accords with the national industry standard. The buoy system used in this paper can also carry a variety of marine environmental factors observation sensors, which can transmit data to the receiving terminal in real time,and which has high application value. |
