This paper introduces the reader to our Kalman filter developed for geodetic VLBI(very long baseline interferometry) data analysis. The focus lies on the EOP(Earth Orientation Parameter) determination
We elaborate an error budget for the long-term accuracy of IGS(International Global Navigation Satellite System Service) polar motion estimates, concluding that it is probably about 25-30 μas(1-sigma)
Previous studies suggest that tidal friction gives rise to the secular deceleration of the Earth rotation by a quantity of about 2.25 ms/cy. Here we just consider additional contributions to the secul
The global Very Long Baseline Interferometry observation for measuring the Earth rotations parameters was launched around 1970 s. Since then the precision of the measurements is continuously improving
