            "description": "NASA's Space Geodesy Project (SGP) uses a variety of space- and land-based techniques to determine the precise shape, position, and orientation of the Earth with respect to the Terrestrial Reference Frame (TRF) and Earth orientation parameters (EOP). This visualization presents a summary of these techniques.The visualization begins with a shot of natural-looking Earth, then transitions to a view that shows the orbital components of the SGP, which include global navigation satellite systems (GNSS), satellite laser ranging (SLR) and Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS). The view then moves to the surface of the Earth, showing the positions and direction of the motion of ground stations as measured by these techniques, as well by ground-based very long baseline interferometry (VLBI), which uses the radio emissions of distant quasars to determine geodetic measurements.We then zoom into the center of the Earth to show the consequence of these surface motions: the movement of the geocenter, which these techniques can determine to within millimeters. || ",

It was originally invented back in the 1960s to take better pictures of quasars, but scientists soon found out that if you threw the process in reverse, you could measure how the ground beneath the telescopes moves around, how long days really are, and how the Earth wobbles on its axis as it revolves around the sun!

Over time, the field of geodesy has expanded and evolved dramatically, and NASA uses technology like radio telescopes, ground surveys, and satellites to contribute!
