Software is widely available to assist with this form of navigation; some of this software has a self-contained ephemeris. [9] When software is used that does not contain an ephemeris, or if no software is used, position data for celestial objects may be obtained from the modern Nautical Almanac or Air Almanac. [10] An ephemeris is usually only ...
XEphem started as a Unix and Motif conversion of the IBM PC-based ephem.It was initially released in December 1993 with version 2.5. [citation needed] Its commercial edition was discontinued in 2016; the free version continued to be offered as proprietary software. [3]
Raphael's Ephemeris was issued as a separate publication after Smith’s death, whilst others adopted and continued with the name 'Raphael'. The "second Raphael" was John Palmer (1807–1837), a former student of Smith's, who edited Raphael's Sanctuary of the Astral Art in 1834; the third was a Mr. Medhurst, the editor of the Prophetic ...
SOLEX can generate ephemeris of Solar System objects, including planets and asteroids. It is capable of predicting their positions several millennia into the past and future, maintaining an accuracy equal to the JPL Horizons On-Line Ephemeris System and the US Navy's Astronomical Almanac . [ 2 ]
Software libraries exist to aid in the development of astronomical software. These libraries can also be leveraged for use in astrological projects. One such tool is Swiss Ephemeris, which is an astronomical almanac developed by Astrodienst AG, Switzerland, the makers of Astrolog. It is widely used for calculating the positions of planets ...
JPL Horizons On-Line Ephemeris System provides access to key Solar System data and flexible production of highly accurate ephemerides for Solar System objects. Osculating elements at a given epoch (such as produced by the JPL Small-Body Database ) are always an approximation to an object's orbit (i.e. an unperturbed conic orbit or a " two-body ...
A particular case-in-point is the Android software which can often be run on laptops or PCs (running Linux, Windows or Mac OS X) as well. This can be done using emulators. Some of the software mentioned here may run only on devices that are no longer commercially sold (such as the PalmPilot and PocketPC devices).
