GMAT is a space trajectory optimization and mission analysis system developed by NASA and private industry in the spirit of the NASA Vision. GMAT is a collaboratively developed, open-source tool that enables the development of new mission concepts and provides capabilities that can improve current mission support in a transparent and verifiable way through release of source code.
The system has been used in support of the Lunar Crater Observation and Sensing Satellite (LCROSS), ARTEMIS (Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon’s Interaction with the Sun) , Lunar Reconnaissance Orbiter (LRO), the Magnetospheric Multiscale (MMS) Mission, and OSIRIS (Origins Spectral Interpretation Resource Identification Security Regolith Explorer).
This release was developed with contributions by Thinking Systems, Inc., and a.i. solutions, Inc. GMAT is offered free of charge to use, modify, and share as described under the terms of the NASA Open Source Agreement v1.3.
