The General Mission Analysis Tool (GMAT) is an open-source tool for space mission design and navigation. GMAT is developed by a team of NASA, private industry, and public and private contributors. The GMAT development team is pleased to announce the release of GMAT version R2026a. For a complete list of new features, compatibility changes, and bug fixes, see the R2026a Release Notes in the Users Guide.

The Orbit Determination Toolbox (ODTBX) is developed by the Navigation & Mission Design branch at NASA Goddard Space Flight Center as an advanced mission simulation and analysis tool used for concept exploration, proposal, early design phase, and/or rapid design center environments. ODTBX functions and utilities are combined in a flexible architecture that allows for modular development of navigation algorithms and simulations.

Tycho is a MATLAB package for mission analysis and ADCS applications. It is composed of four sub-packages: a) an orbits toolbox which implements basic Keplerian and generalized orbit functions (physical state to Keplerian parameters and generalized parameters, time to true anomaly, etc.). It also implements tools to design impulsive maneuvers to change any of the five applicable Keplerian parameters. A dedicated function exports orbits as .xyzv Celestia files. b) a perturbations toolbox that allows to numerically assess the effect of arbitrary perturbations by integrating Gauss equations. ...
