Abstract: The deformation of ocean tide loading is one of important errors of GNSS real-time observation in coastal areas of China. Analyzing and determining the most suitable ocean tide model for loading correction is critical for improving the accuracy and reliability of GNSS solution. The accuracy of the latest global ocean tide models FES2014, EOT20 and TPXO9 were evaluated with the Root Sum Squares (RSS) of 8 main tidal constituents M₂, S₂, N₂, K₂, K₁, O₁, P₁ and Q₁ based on the tide gauges data observed during a 3-year period in the coastal areas of China. The results show that, compared with the earlier models FES2004, EOT11a, and TPXO7.2, the accuracy improvement in FES2014, EOT20 and TPXO9 in the coastal areas of China is 72.39%, 67.73% and 31.37%, respectively. The performance of FES2014 is best in the coastal areas of China with RSS mean and standard deviation of 7.91 cm and 7.75 cm, respectively. The accuracy of EOT20 is slightly lower than that of FES2014, but significantly better than those of NAO.99jb and NAO.99b, which were considered to be the best models in China seas. The accuracy of TPXO9 is the lowest among the three latest models. It is worth to note that, different ocean tide models have their own best applicable areas, and we can choose appropriate model to correct the ocean tide loading in the precise processing of GNSS data in the coastal areas of China.
