The International Terrestrial Reference System (ITRS) is a global reference system for positioning and measuring locations on the Earth. It provides a standardized framework for defining the position and motion of points on the Earth's surface and within its geophysical environment. The ITRS is crucial for a wide range of scientific and practical applications, including geodesy, navigation, satellite positioning, and Earth observation.
