WebIERS Bulletin B provides current information on the Earth's orientation in the IERS Reference System. This includes Universal Time, coordinates of the terrestrial pole, and celestial pole offsets. IERS Bulletin B consists of 5 sections: Section 1: Daily final values at 0:00 UT of x, y, UT1-UTC, dX, dY, and their uncertainties. http://www.unoosa.org/pdf/icg/2012/icg-7/wg/wgd1-1.pdf iet network security

WebThe origin P i P i of the quasi-inertial coordinate frame (i-frame) is located in the Earth’s center of mass. The first axis i1 i 1 points towards the point of intersection at time t0 t 0 of the zero meridian and the equatorial plane. The third axis i3 i 3 points from the origin towards the IERS reference pole. Web1. x and y are the coordinates of the Celestial Ephemeris Pole (CEP) relative to the IRP. The CEP differs from the instantaneous rotation axis by quasi-diurnal terms with amplitudes under 0.01" (see Seidelmann, 1982).

WebA CONVENTIONAL MEAN POLE PATH The gradual drift of the pole associated with the rotational axis of the Earth in a terrestrial reference frame is characterized by the motion of a "mean pole."
