GMAT R2022a was built for MacOS 12 (Monterey) and 13 (Ventura) based machines, and has been tested on those platforms. MacOS 14 (Sonoma) is showing run time issues for the GMAT GUI on Apple Silicon (M1, M2, M3) based machines. The GMAT Console application continues to run as expected on MacOS Sonoma for these machines. MacOS development is currently paused due to funding issues. We will address the Sonoma runtime issues when resources become available.

The GMAT development team is pleased to announce the release of GMAT version R2022a. New features in this release include TLE and covariance propagation, N-plate SRP models and solve-fors, an operational Extended Kalman Filter Smoother, planetographic (e.g., South Atlantic Anomaly) region entry and exit calculations, an Initial Orbit Determination (IOD) capability and contact calculations using station masks. In addition, the API interface is now production quality. For a complete list of new features, compatibility changes, and bug fixes, see the R2022a Release Notes in the Users Guide. ... read more

The GMAT development team is pleased to announce the release of GMAT version R2020a. See the attached Release Notes. New features in this release include a new 3D graphics engine based on OpenFrames, the first production-quality C++ release of the Collocation Stand-Alone Library and Toolkit (CSALT), a new optimal control subsystem that supports finite-thrust optimization, a new (beta) API developed to provide users low-level access to GMAT functionality and to support interoperability between NASA's GMAT, Copernicus, and MONTE software applications, a new continuous thrust mission design and navigation feature, and a new (alpha) Extended Kalman Filter Smoother with process noise. For a complete list of new features, compatibility changes, and bug fixes, see the Release Notes in the Users Guide.... read more

The GMAT development team is pleased to announce the release of GMAT version R2015a. The General Mission Analysis Tool (GMAT) is the world’s only enterprise, multi-mission, open source software system for space mission design, optimization, and navigation. The system supports missions in flight regimes ranging from low Earth orbit to lunar, libration point, and deep space missions. GMAT is developed by a team of NASA, private industry, public, and private contributors and is used for real-world mission support, engineering studies, as a tool for education, and public engagement.... read more
