While GMAT has undergone
extensive testing and is mature software, we consider the system to be in beta form on some platforms
and alpha form on others. The GMAT team considers the system to be in an alpha release state as long as the system
is functional, but has not been rigorously tested for numerical precision and functional
stability. Once testing has been performed and stability verified, the system becomes a beta
product if the number of open issues is considered small and the system is usable for most problems.
GMAT has the following status on the supported platforms:
Windows: Beta
Mac: Alpha
Linux: Alpha
We are in the process of performing significant testing to prepare GMAT for operational use. GMAT's numerics and models have received extensive testing against operational systems. The dynamics models, integrators, propagators, coordinate systems, and parameter calculations meet the project's acceptance criteria, with only a few exceptions. Please see the Acceptance Test Plan to learn more about the few cases where numerical issues still exist. For a detailed list of existing bugs and issues, please visit the project's Bug Tracker.
The GMAT Team is currently working on four activities: Maintenance and bug fixes, expanding the architectural specification, testing, and transitioning to an open source development process. The objective of the current development cycle is to provide a build for final beta testing in November.
