GMAT is available as a platform-independent source code bundle. Note that all testing is performed on Windows, so on other platforms it is considered a beta release. See the GMAT Wiki for compiling instructions.

There are tags available for reach release.
On Microsoft Windows platforms there are several ways to start a
GMAT session. If you used the GMAT installer, you can click the
GMAT R2018a item in the

The GMAT distribution includes more than 30 sample missions. These samples show how to apply GMAT to problems ranging from the Hohmann transfer to libration point station-keeping to trajectory optimization. To locate and run a sample mission:
On the toolbar click Open.
Navigate to the
samplesfolder located in the GMAT root directory.
Double-click a script file of your choice.
Click Run ().
To run optimization missions, you will need MATLAB and the MATLAB
Optimization Toolbox or the internal
plugin. These are proprietary libraries and are not distributed with GMAT.
MATLAB connectivity is not yet fully supported in the Mac and Linux, and

fmincon optimizer on those platforms. See MATLAB Interface for details on configuring the MATLAB
