42 is a comprehensive general-purpose simulation of spacecraft attitude and orbit dynamics. Its primary purpose is to support design and validation of attitude control systems, from concept studies through integration and test. 42 accurately models multi-body spacecraft attitude dynamics (with rigid and/or flexible bodies), and both two-body and three-body orbital flight regimes, modelling environments from low Earth orbit to throughout the solar system. 42 simulates multiple spacecraft concurrently, facilitating studies of rendezvous, proximity operations, and precision formation flying. ...

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.

Calculate electronic properties of graphene-like systems with a user friendly interface. The code uses the tight binding approximation and it is able to stude in a 0D, 1D and 2D geometries, orbital and magnetic fields, intrinsic and extrinsic spin-orbit coupling, sublattice imbalance, and interactions at the mean field level.

a program for astrodynamics, written in C++ include orbit propagator, formation, etc

User friendly interface for calculating electronic properties in graphene-like ribbons. The programs uses the tight binding approximation and mean field Hubbard model to predict electronic properties of graphene-like nanoribbons. See Discussion to ask questions or details Update: New versions of this program will be known as quantum-honeycomp

GGOS is a Graphical Simulator of the gravity interaction written in C. It provides a real-time tracking of the orbit and the user can interact with the universe with a lot of function. There is 2 different version:1(fast)with X11 2(slow)written with GLUT

Orbzilla is a flexible framework for orbit determination. It mechanizes the process of creating batch and Kalman filters to process spacecraft observations.

Orbit is currently a simple orbital simulator for simple circular orbits. It ultimately aims to be a general gravity machine, which will allow the instant creation of galaxies.

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. ...
