MICA - Multiyear Interactive Computer Almanac
MICA is
an easy-to-use program that computes many of the quantities tabulated
in The Astronomical Almanac,
but it covers the 250-year period 1800-2050. It allows the user to compute this
information for specific locations and precise times. Several catalogs of
celestial objects, including an astrometric catalog of about 230,000 stars, are
included with the program. MICA is available in Windows and Macintosh editions.
Current version: 2.2.2 [Updated January 2012].
NOVAS - Naval Observatory Vector Astrometry Software
NOVAS is an
integrated package of subroutines and functions for computing various commonly
needed quantities in positional astronomy. Available as Fortran, C, or Python source
code.
Current version: 3.1 [Updated March 2011].
Software Products by Our Colleagues
NavPac and Compact Data 2011-2015
This product is a publication of Her Majesty's Nautical Almanac Office (HMNAO) of the United Kingdom. The NavPac software, supplied on CD-ROM, enables navigators to easily compute their position at sea from observations made with a sextant. Compact Data, the book supplied with NavPac, provides simple, efficient and consistent formulae and methods for calculating the positions of the Sun, Moon, navigational planets, and stars, as well as sight reduction using a personal computer or programmable calculator.
Standards Of Fundamental Astronomy (SOFA) Libraries
The International Astronomical Union's SOFA initiative seeks to promulgate an authoritative set of fundamental-astronomy constants and algorithms. The initiative is managed by an international panel, the SOFA Reviewing Board, appointed through IAU Division 1. The SOFA software libraries are a collection of subprograms, in source-code form, that implement official IAU algorithms for fundamental-astronomy computations. Visit the SOFA Web site for details.
