Iers terrestrial reference system
WebThe IERS was established by the International Astronomical Union and the International Union of Geodesy and Geophysics. The IERS provides data on Earth orientation, on the International Celestial Reference System/Frame, on the International Terrestrial Reference System/Frame, and monitors the difference between UT1 and UTC. Contacts WebInternational Terrestrial Reference System (ITRS). Definition of Frame • Origin: Earth’s center of mass being defined for the whole Earth including oceans and atmosphere • Axes: o Z-Axis = The direction of the IERS Reference Pole (IRP). This direction corresponds to the direction of the BIH Conventional Terrestrial Pole (CTP)

Webreference frame established in 1987 was realized through a set of Navy Navigation Satellite System (NNSS) or TRANSIT (Doppler) station coordinates. The main objective in the original effort was to align, as closely as possible, the origin, scale and orientation of the WGS 84 frame with the BIH Terrestrial System (BTS) frame at an epoch of 1984.0. Web9 nov. 2015 · Terrestrial reference systems and reference frames define the parameters necessary to the establish coordinate systems. A reference system is an unequivocal specification of conventions, algorithms and numerical constants. The ability to build a reference system that can be realized on a global scale is a fairly recent development.
