During 1994–1996 Ephemerides have been intensively developed for all celestial bodies in the solar system in both analytical and numerical ways, except an analytical ephemeris of Pluto. Because of the shortage of allotted pages this report covers o

Classical Methods for the Determination of Universal Time and Polar Motion
Autor: B. D. Yallop, N. P. J. Ohora
Publikováno v: International Astronomical Union Colloquium. 26:303-308
A brief historical survey of important improvements in the classical methods for the determination of universal time and of polar motion over the last 25 years is outlined. Some of the errors that affect the results and estimates of the ultimate accu

The period of this Report includes 1984 January 1, the date which was probably the most drastic caesura in the history of astronomical almanacs. It seemed, therefore, appropriate to concentrate here to the general aspects rather than to describe the

Because of unforeseen difficulties, Dr Sinzi, President of the Commission, was not able to prepare this Report. It was then too late for asking the Directors of the almanac offices and the other Members of the Commission for informations. This Report

Lunar laser ranging and fundamental astrometry
Autor: B. D. Yallop, C. A. Murray
Publikováno v: Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences. 284:507-514
The frame of reference to which a positional astronomer refers his observations is defined by the directions of the Earth’s axis and of the equinox. This frame rotates relative to an inertial frame owing to the precessional motion. Traditionally, t
