Geodetics - NASA Earthdata Geodetics, or geodesy, is the science of studying Earth’s shape, gravity and its effect on phenomena such as polar motion, waterbody tides, and tectonic motion in three-dimensional space over time Geodetic data has many uses including measuring the changes to Earth's tectonic plates following earthquakes and other crustal dynamics, tracking variations in ocean topography, and locating Earth
Space Geodesy Techniques - NASA Earthdata Data provided by space geodesy techniques are used to support scientific and societal applications in areas such as Earth observations, positioning, navigation, and timing

Beacons in the Sky Help Monitor Earths Orientation in Space | NASA . . . In addition to VLBI telescopes, this terrestrial framework includes three other space-geodetic techniques and their instruments: Satellite Laser Ranging (SLR) telescopes, Global Navigation Satellite Systems (GNSS) antennas, and Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS) beacons
Very Long Baseline Interferometry | NASA Earthdata Very Long Baseline Interferometry (VLBI) is a geometric technique that measures the time difference between the arrival at two Earth-based antennas of a radio wavefront emitted by a distant quasar
