Lunar
Welcome
This web
site contains computer programs that can be used for the practical solution of
astrodynamic problems related to lunar mission analysis, orbit design and
trajectory optimization. Computer
applications are available in the form of MATLAB scripts, executable programs
and Fortran source code. The MATLAB
scripts were created with version 7.2 (R2006a).
The Fortran executable programs were created with version 6.6c of Compaq
Visual Fortran.
The
software for sale at this web site can be purchased using the flexible and
secure e-commerce features offered by PayPal (www.paypal.com). PayPal accepts online payments by
credit card and a PayPal account is not required to make a purchase. Before placing an order, please read the license agreement. After placing your order, you will receive an
email within 24 hours with a password that will permit you to extract the
source code or executable program and any support data files.

PLEASE NOTE:
The MATLAB scripts marked with SNOPT were written for use with the SNOPT
nonlinear programming (NLP) algorithm.
MATLAB versions of SNOPT 6.0 for several computer platforms can be found
at Professor Philip Gills web site which is located at http://scicomp.ucsd.edu/~peg/. A PDF version of the SNOPT users manual is
also available at that website.
