Geodetics Data Access and Tools
NASA has geodetics datasets that help researchers characterize the shape of Earth and the motion of its components. Access a range of data and data tools such as AppEEARS, Worldview, and Giovanni to make the most of geodetics data.
Featured Geodetics Observation Method: GNSS
A Global Navigation Satellite System (GNSS) is a space geodesy technology that provides autonomous geospatial positioning around the world. One such system is the U.S. Global Positioning System (GPS), which is made up of 24 satellites, each traveling in a 12-hour orbit. A similar system is the GLObal NAvigation Satellite System (GLONASS) constellation consisting of 24 satellites. Each system is designed so that multiple satellites are within range of any point on Earth in order to precisely determine its location.
GNSS data can used to determine location and positioning around Earth as well as to study geophysics, the motions of tectonic plates and their displacements due to earthquakes, Earth orientation, and atmospheric properties among many other things.
