On comparison of the Earth orientation parameters obtained from different VLBI networks and observing programs
In this paper, a new geometry index of Very Long Baseline Interferometry (VLBI) observing networks, the volume of network V , is examined as an indicator of the errors in the Earth orientation parameters (EOP) obtained from VLBI observations. It has been shown that both EOP precision and accuracy can be well described by the power law σ = aV c in a wide range of the network size from domestic t...
متن کاملDetermination of Sub-daily Earth Rotation Parameters from VLBI Observations
The work presented deals with the determination of sub-daily Earth Rotation Parameters (ERPs) from Very Long Baseline Interferometry (VLBI) observations. Monitoring and interpreting the Earth's rotation variations in general is an important task for Earth sciences, as they provide boundary which support other geophysical investigations. This holds especially for sub-daily variations of the Eart...
متن کاملUsing the Earth orientation parameters to link the Hipparcos and VLBI reference frames
One of the methods, used to link the free Hipparcos reference system to the conventional extragalactic reference system, is the indirect method using the rapidly rotating terrestrial reference system as an intermediary. We solve the Earth orientation parameters, referred to the preliminary Hipparcos reference frame H37C, from the observations made by the classical methods of optical astrometry ...
متن کاملA Quaternion-based Unscented Kalman Filter for Orientation Tracking
This paper describes a Kalman filter for the real-time estimation of a rigid body orientation from measurements of acceleration, angular velocity and magnetic field strength. A quaternion representation of the orientation is computationally effective and avoids problems with singularities. The nonlinear relationship between estimated orientation and expected measurement prevent the usage of a c...
متن کاملNon-linear VLBI station motions and their impact on the celestial reference frame and Earth orientation parameters.
The increasing accuracy and growing time span of Very Long Baseline Interferometry (VLBI) observations allow the determination of seasonal signals in station positions which still remain unmodelled in conventional analysis approaches. In this study we focus on the impact of the neglected seasonal signals in the station displacement on the celestial reference frame and Earth orientation paramete...
