Crustal Motion Data Access and Tools

Crustal motion data from NASA includes Earth orientation time series and navigation satellite orbit and reference frame products. Our datasets and tools help users find and integrate the data they need to unearth crustal motion characteristics and how they relate to Earth’s dynamics, navigation, and more.

Featured Crustal Motion Observation Method: GNSS
A Global Navigation Satellite System (GNSS) allows user to precisely locate positions around the world. One such GNSS is the U.S. Global Positioning System (GPS), which is made up of 24 satellites. A GNSS is designed so that multiple satellites are within range of any point on Earth in order to determine its location.

GNSS data can used to study crustal motion, geophysics, plate tectonics, and atmospheric properties in addition to many other topics.
