Innovators at NASA's Johnson Space Center (JSC) have developed a collection of mathematical models to generate vehicle trajectories using a set of dynamics models represented as differential equations. The JSC Engineering Orbital Dynamics (JEOD) Software includes a reusable set of orbital dynamics models. The JEOD mathematical model set includes seven categories of functional capabilities, with each capability implemented in a collection of software modules written in the ANSI® C programming language. While the modules are designed to work with NASA's Trick Simulation Development Environment, they also can be used in virtually any time-stepped integrated simulation software package. This software may be released for U.S. Government purposes only.

- Efficient: Provides a reusable, verified, validated, and documented orbital dynamics package for general time-stepped, integrated space-based simulations
- Proven: Provides a well-tested orbital dynamics environment for space-based simulations
- Economical: Reduces the cost and time of simulation development while increasing the reliability and credibility of the simulation results
- Vehicle trajectory mission planning
