Research on the operational regional coverage of satellite and spacecraft tracking and controlling [PDF]
MATEC Web of Conferences, 2020 In view of the problem of building ground stations for tracking and controlling of satellites and spacecraft, considering the fixed angle between the orbit of the satellite or spacecraft and the equatorial surface of the earth, and the difference of ...

Are Ocean Reanalyses Useful for Earth Rotation Research?
Earth and Space Science, 2023 Oceanic circulation and mass‐field variability play important roles in exciting Earth's wobbles and length‐of‐day changes (ΔΛ), on time scales from days to several years.

Empirical Earth rotation model: a consistent way to evaluate Earth orientation parameters [PDF]
, 2006 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

Considerations regarding the variability of Earth-Sun geometry and the climate variability in south-western Romania [PDF]
Riscuri şi Catastrofe, 2019 The variability of the Sun-Earth geometry is particularly high during the year due to the specific trajectory of the planet Earth around the Sun, the rotation motion of the Earth around its axis, the inclination of the rotation axis with respect to the ...

On the Planetary acceleration and the Rotation of the Earth [PDF]
, 2007 We have developed a model for the Earth rotation that gives a good account (data) of the Earth astronomical parameters. These data can be compared with the ones obtained using space-base telescopes.

Earth's Rotation and Solar Activity [PDF]
Geophysical Journal International, 1989 Summary The 11-yr signal in the variation of length of day has been successfully identified and significantly linked to solar activity. A physical mechanism involving meteorological and oceanic variation is proposed.

Mountain building and earth rotation [PDF]
Geophysical Journal International, 1994 SUMMARY Whereas the present-day true polar wander and the secular non-tidal acceleration of the Earth have usually been attributed to postglacial rebound, it has recently been suggested that non-glacially induced vertical tectonic movements taking place under non-isostatic conditions can also be effective in changing the Earth's rotation. We present

On the equilibrium rotation of Earth-like extra-solar planets [PDF]
, 2008 The equilibrium rotation of tidally evolved "Earth-like" extra-solar planets is often assumed to be synchronous with their orbital mean motion. The same assumption persisted for Mercury and Venus until radar observations revealed their true spin rates ...
