Reading Time: < 1 minute NASA’s General Mission Analysis Tool (GMAT) is used for orbital mechanics simulation and mission design. Since version R2022a, it has included a Python API. I’ve often found this tricky to use, though, so am writing my own wrapper for it. You can see all its latest developments in its repo:
An extra wrapper for the GMAT Python API to simplify setting up mission simulations. https://github.com/weasdown/GMAT-Python-simple 3 forks.20 stars.6 open issues.
