Explore: Satellite Altimetry

Satellite geodesy is geodesy by means of artificial satellites—the measurement of the form and dimensions of Earth, the location of objects on its surface

methods, from depth sounding, sonar and lidar techniques, to buoys and satellite altimetry. Various methods have advantages and disadvantages and the specific

completed by Tsimplis and Woodworth in 1994 at the beginning of the satellite altimetry era. In general, amplitudes of the annual cycle are less than 150mm

with high accuracy and precision at regional to global scale by satellite altimetry (e.g. TOPEX/Poseidon). Slower and larger variations are due to changes

an object above a fixed level. The measurement of altitude is called altimetry, which is related to the term bathymetry, the measurement of depth under

GRAV-D program as well as satellite-based gravity models derived from observations collected by GRACE, GOCE, and satellite altimetry missions. NGS provides
