Abstract

Nowadays, the coastal tide observation technology has developed very well. However, there still lacks a reliable and quick method of acquiring tidal level in open sea areas. To overcome this problem, a GNSS buoy has been developed, which is equipped with data acquisition system and shore station system. Also, some tidal level extraction algorithms are also proposed. Based on Precision Point Positioning, the GNSS data is calculated. Kalman filtering, attitude correction, smoothing, and sampling are performed on the high-frequency GNSS solution results. And the above results are corrected using the prior periodic information. The tidal level derived from the GNSS buoy without and with prior periodic information are compared with the tidal level derived from the regional tide model (NAO.99Jb). The RMSE are 7.6cm and 4.8cm, respectively. Also, the tidal level derived from the GNSS buoy with prior periodic information in spring tide period are less accurate than it in neap tide period. The RMSE are 6.4cm and 3.7cm, respectively. The results show that GNSS buoy can provide high accuracy tidal level.
