General Astrodynamics Library

A new version of the General Astrodynamics Library is now available.

In a posting on the AMSAT Bulletin Board (AMSAT-BB) Paul Willmott, VP9MU, writes:

Version 0.3.0 of the General Astrodynamics Library has been released. It can be downloaded from the project website here: http://homepage.mac.com/pclwillmott/GAL/index.html

Updates in this release:

· ODE Integrator sub-library created.

· Lunar position and velocity routine added to ephemerides sub-library. Routine implements LUNAR SOLUTION ELP version ELP/MPP02

· Solar position and velocity routine added to ephemerides sub-library.

· Acceleration from spherical harmonics routine added to gravity sub-library.

· Many routines updated for internal compatibilty with the upcoming official IAU SOFA C library.

· R-matrices have had indicies reversed compared to GAL 0.2 and earlier.

Work will now be started on the classical keplerian models, and atmosphere models.

The General Astrodynamics Library (GAL) is a numerical library for C and C++ programmers. It is free software under the GNU General Public License.

The library provides a wide range of astrodynamical routines such as ephemerides, earth orientation, and orbit propagation. There are over 225 functions in total with an extensive test suite.
