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. 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." The IERS Conventions (2010) does not provide a formal definition of such a "mean pole." In its glossary it defines the terminology "mean pole" in the celestial frame …

WebSince 1988, the IERS has defined the mean spin axis, the IERS Reference Pole, the zero meridian and the IERS Reference Meridian. Whilst WGS-84 is not a dynamic model, the maintenance of a datum at a higher level of accuracy as for the ITRS requires constant monitoring of the rotation of the Earth, the motion of the pole and the movement of the … WebIRM IERS Reference Meridian IRP IERS Reference Pole ITRF IERS Terrestrial Reference Frame JD Julian Day LOS Line of Sight LNP Local Normal Pointing MLST Mean Local Solar Time MJD2000 Modified Julian Day of 2000 OBT On-Board Time SBT Satellite Binary Time SGP4 Simplified General Perturbations Satellite Orbit Model 4
