GPS is making possible high‐precision, high‐resolution measurements of tidal displacement that could not be achieved with other methods. Earth's surface deforms due to both body tides—the deformation of the solid Earth due to the pull of the Sun and the Moon—and ocean tides—the redistribution of water mass loading over Earth's surface. Body tides and ocean tides both have components that vary on semidiurnal, diurnal, and longer periods.
