| Abstract: | Based on MATLAB GUI interface, we compile a set of tide correction software GTIDE for gravity solid tide and ocean tide loading using zenith distance and Green’s function method. We analyze the reliability and applicability of GTIDE through comparison with existing international software. The results show that software is easy to operate and maintain, and its results can effectively reveal the variation characteristics of gravity solid tide and ocean tide loading. The GTIDE can be using for tide corrections of high-precision absolute gravity and relative gravity measurements. |
