A new Parameterization of Polar Motion,ed as a function of the rotation vector components. In the rigid earth approximation three scalar parameters are necessary for evaluating point coordinate variations, namely spin rate of the earth, polar motion magnitude and spin rate of the polar motion vector. Two numerical examples are given as an illustration.作者: habitat 時間: 2025-3-22 12:21 作者: 強所 時間: 2025-3-22 16:29 作者: 哀悼 時間: 2025-3-22 20:52
Relativistic Effects in Reference Frames,I, and similar effects are reviewed; they are usually on the order of 10. . Finally, the problem of a possible variation of the gravitational constant G (on the order of 10./year) is outlined; such a variation does not occur in special and general relativity, but is implied by certain generalized field theories which are less commonly accepted.作者: 過于光澤 時間: 2025-3-22 22:08 作者: 和平 時間: 2025-3-23 04:27

Ideal Reference Frames, Concepts and Interrelationships, necessary, to use a reference frame. To use a reference frame, a scheme is needed by which the coordinates of any point expressed in this frame could be obtained. Coordinates are hardly ever measured directly.

The short period variations are nearly diurnal and semi-diurnal and are supposed to be due to nutations and Earth tides.

Reference Coordinate System Requirements for Space Physics and Astronomy,are currently in a phase where measurement capability has far outdistanced the capacity for theoretical interpretation. Simply to provide descriptive models, we are driven to computational complexity undreamed of two decades ago.

On the Establishment of Terrestrial Coordinate System by Classical Techniques,The definition and practical realization of the astronomical system of terrestrial coordinates are discussed. In particular, the separation of secular polar motion and nonpolar drift of observatories are touched upon as far as those phenomena are crucially intertwined with the realization of a terrestrial coordinate system.作者: NOVA 時間: 2025-3-29 05:09
On Reference Coordinate Systems Used in Polar Motion Determinations,A short review of the reference pole presently used in polar motion determinations by classical astrometric methods is followed by a discussion of the systematic differences between systems of polar coordinates and the influence of the mean latitude of stations on pole position. The importance of homogenous processing astrometric data is stressed.作者: Chagrin 時間: 2025-3-29 10:01 作者: Oratory 時間: 2025-3-29 12:48

In this paper, introducing a parameter associated to a mean seasonal kinetic energy we show evidence of about 4 year and 7 yr periodicity. This result is briefly discussed.作者: attenuate 時間: 2025-3-29 15:52
