Interplanetary
Welcome
This web site contains Windows compatible computer programs and
MATLAB scripts that can be used for the practical solution of astrodynamic problems related to interplanetary mission
analysis, orbit design and trajectory optimization. The MATLAB scripts were created with version
R2010b. The Fortran
executable programs were created with Intel Visual Fortran, version 11.1.
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 password protected MATLAB source code or executable program and any support data files.

PLEASE NOTE: The
MATLAB scripts flagged with (SNOPT) were written for use with the SNOPT
nonlinear programming (NLP) algorithm. MATLAB
versions of SNOPT for several computer platforms can be found at Professor
Philip Gill’s web site which is located at http://scicomp.ucsd.edu/~peg/. A PDF version of the SNOPT user’s manual is
also available at that website. Both of
these scripts have been tested with Windows XP Professional (32 bit), Windows 7
Home Premium (32 bit), versions R2010a, R2010b and R2011a of MATLAB, and the
12/30/2010 version of SNOPT. The JPL
DE421 binary ephemeris file is required by these scripts. The version provided here is compatible with
Windows platforms only.
