Embodiment Construction
[0048] The following detailed description is exemplary and intended to provide further explanation of the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It should be noted that the terminology used herein is for the purpose of describing specific embodiments only, and is not intended to limit the exemplary embodiments according to the present application.
[0049] figure 1 As shown, a method for establishing a time-varying ocean tide load displacement model based on GNSS technology includes the following steps:
[0050] S1. Calculate the hourly solution for the GNSS data, do not correct the tide load during the calculation process, and obtain the dynamic GNSS coordinate time series;
[0051] S2. Use the harmonic analysis algorithm of band-pass filtering to estimate the static ocean tide load displacement parameters...
