چکیده
Abstract The accurate knowledge of the Earth’s orientation and rotation in space is essential for a broad variety scientific societal applications. Among others, these include global positioning, near-Earth deep-space navigation, realisation precise reference time systems as well studies geodynamics change phenomena. In this paper, we present refined strategy processing combining Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), Global Navigation Systems (GNSS), Doppler Orbitography Radiopositioning Integrated by (DORIS) observations at normal equation level formulate recommendations consistent space-geodetic input data. Based on developed strategy, determine final rapid Earth parameter (ERP) solutions with low latency that also serve basis subsequent prediction ERPs involving effective angular momentum Realising an accuracy comparable to ERP benchmark IERS 14C04 JPL COMB2018, our allows enhance consistency between final, predicted terms RMS differences up 50% compared existing solutions. findings study thus support ambitious goals Geodetic Observing System (GGOS) providing highly series geodetic parameters science

Empirical Earth rotation model: a consistent way to evaluate Earth orientation parameters
It is customary to perform analysis of the Earth’s rotation in two steps: first, to present results of estimation of the Earth orientation parameters in the form of time series based on a simplified model of variations of the Earth’s rotation for a short period of time, and then to process this time series of adjustments by applying smoothing, re-sampling and other numerical algorithms. Althoug...
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...
