ALL OF THE SUN, THE MOON AND ALL THE PLANETS OF THE SOLAR SYSTEM - FOR THE YEARS BETWEEN 1900 AND 2100.
SOLARARK high accurate astronomy software SOLARARK softwares:
THE POSITIONS AND EPHEMERIDES FOR THE SUN, THE EARTH, THE MOON AND THE PLANETS OF THE SOLAR SYSTEM ARE CALCULATED USING THE BRETAGNON AND FRANCOU "VSOP87" (VARIATIONS S╔CULAIRES DES ORBITES PLAN╔TAIRES) PLANET THEORY. THIS IS BASED ON THE OLDER JPL DE200 NUMERICAL INTEGRATION (WHICH STILL FORMS THE BASIS OF THE TABULATED PLANETARY POSITIONS IN THE "ASTRONOMICAL ALMANAC".
IN ALL CASES, POSITIONS ARE INITIALLY CALCULATED IN A HELIOCENTRIC REFERENCE FRAME, AND THEN RIGOROUSLY REDUCED TO A GEOCENTRIC FRAME, APPLYING CORRECTIONS FOR LIGHT TRAVEL TIME, GRAVITATIONAL DEFLECTION OF LIGHT BY THE PLANET, AND ANNUAL ABERRATION. THE GEOCENTRIC POSITION IS THEN CONVERTED TO A TOPOCENTRIC POSITION .

The positions and ephemerides for the Sun, the Earth, the Moon and the planets of the solar system are calculated using the Bretagnon and Francou "VSOP87" (Variations SÚculaires des Orbites PlanÚtaires) planet theory. This is based on the older JPL DE200 numerical integration (which still forms the basis of the tabulated planetary positions in the "Astronomical Almanac". In all cases, positions are initially calculated in a heliocentric reference frame, and then rigorously reduced to a geocentric frame, applying corrections for light travel time, gravitational deflection of light by the planet, and annual aberration. The geocentric position is then converted to a topocentric position.
