Contribution of Etalon Observation to Earth Rotation Parameters under a New Observation Scenario
Applied Sciences, 2022 The standard products of the International Laser Ranging Service (ILRS) are mainly based on the two laser geodynamics satellites (LAGEOS) due to the sparse observations of the Etalon satellites.

Earth rotation parameter estimation from LLR [PDF]
Advances in Space Research, 2022 Lunar Laser Ranging (LLR) measures the distance between observatories on Earth and retro-reflectors on Moon since 1969. In this paper, we estimate the Earth Rotation Parameters (ERP; terrestrial pole offsets, x_P and y_P , and Earth rotation phase, DeltaUT1) using LLR data.

Oscillatory Modes оf the Atmosphere оf Jupiter аnd Venus
Наука. Инновации. Технологии, 2023 Introduction. The article studies the oscillatory modes of the atmosphere of two planets (Jupiter, Venus), taking into account the influence of axial rotation, which affects the occurrence of beating and resonance, and comparing their parameters with the

Requirements for Earth Rotation Parameters [PDF]
Highlights of Astronomy, 1986 AbstractObservations of Earth orientation parameters (polar motion and Universal Time) have reached a level of accuracy which challenges the definition of the reference systems which these observations seek to relate. Observational accuracies of better than in polar motion and in Universal Time are now routinely available.

Kinematical Relativistic Corrections for Earth’s Rotation Parameters [PDF]
International Astronomical Union Colloquium, 2000 AbstractDynamical theories of the Earth’s rotation like SMART97 (Bretagnon et al., 1998) are to be considered in a DGRS (dynamically nonrotating geocentric reference system) (Brumberg et al., 1996). Such a theory gives the explicit expressions in terms of TCG (Geocentric Coordinate Time) of three Euler angles relating a DGRS to the ITRS (International ...
