Abstract
Using GPS data of 4 CORS stations in Hong Kong 2012, four ocean tide semidiurnal constituents’ vertical displacement parameters of every station were calculated. Firstly, 4 stations’ displacement time series were extracted by GPS PPP algorithm. Next, combined with harmonic analysis method, the vertical displacement parameters of semidiurnal constituents were obtained. Simultaneously, in order to evaluate accuracy and reliability of ocean loading displacement parameters determined by PPP technology, we compared the results with ocean loading displacement parameters provided by HAMTIDE11A.2011 global ocean tide model refined by local tidal data of eastern and southern sea of China and the difference was less than 1 mm. Therefore, PPP techniques can be used for measuring ocean tide loading displacement parameters, and it has implications for precision modeling of tides and high-precision geodetic measurements.
