The GMAT development team is pleased to announce the release of GMAT version R2020aR2022a. The binaries are available here. 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.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 Release Notes In recent news, wein the Users Guide. We are excited to report that GMAT continues to see significant adoption for operational mission support :. For example, the Fermi low Earth NASA mission, which uses the GPS point solution data type for ground based orbit determination, started using GMAT's Extended Kalman Filter Smoother (EKFS) orbit determination capability for future release. A publicly available version of GMAT, with EKFS capabilities for all data types supported by GMAT, is planned for the R2021a release.The GMAT team is currently integrating CSALT into GSFC's Core Flight System (cFS) to demonstrate the ability to perform optimal control onboardfor operations in July 2021. |
Do you want to go to Mars but don't know when to leave or how much to bring? Do you want to land something on the moon? The General Mission Analysis Tool (GMAT) is an open-source space mission analysis tool to answer just those types of questions. GMAT is developed by a team of NASA, private industry, public, and private contributors. GMAT is intended both for real-world engineering design studies and as a tool for education and public engagement in the spirit of the NASA Charter.
