Software Products by Our Colleagues
NavPac and Compact Data
This
product
is a publication of
His 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.

SOFA Web site
