The Orbital and Celestial Mechanics Website
Freeware
Welcome
This web site
describes a collection of Windows XP/Vista computer programs that can be used
to solve a variety of practical problems in astrodynamics
and celestial mechanics. Several of
these applications were written using Compaq Visual Fortran, version 6.6, and
the DISLIN library (www.dislin.de) for the
graphical user interface (GUI) and analysis graphics. All executable programs are offered as
freeware and can be re-distributed for non-commercial purposes. The Fortran source
code for several computer programs is available for purchase.
