In the recent papers (Brzezinski, 2012, J. Geodynamics 62, 74-82; Böhm et al., 2012, J. Geodynamics 62, 56-68) we gave theoretical background and shown practical application of the complex demodulation procedure for extracting the diurnal and semidiurnal signals in Earth rotation from the Very Long Baseline Interferometry (VLBI) observations. Here we address the question if the determination from VLBI can be improved by taking into account observations of the ring laser gyroscope (RLG). We consider first the use of one RLG with the parameters of the real RLG in Wettzell, and then simulate the use of several RLG’s at various locations worldwide.
