Innovators at NASA’s Johnson Space Center (JSC) have developed a software package that includes a collection of environment and dynamics models to represent the dynamic state of a spacecraft in a planetary environment. JSC’s Engineering Orbital Dynamics (JEOD) Version 2.0 extends the capabilities of JEOD Version 1.4 to allow users to model scenarios anywhere in outer space. JEOD is a collection of mathematical models, represented as differential equations, used to generate vehicle trajectories. JEOD Version 2.0 has a more flexible coordinate system framework and management scheme as well as a new time scale model that better supports multiple and nonlinear time scales. The package has been completely recoded in the C++ programming language and now incorporates an object-oriented framework designed for reuse, extensibility, and long-term growth. These and other modifications combine to provide better long-term spacecraft modeling and simulation support for exploration initiatives. This software may be released for U.S. Government purposes only.
This technology is being made available through JSC’s Technology Transfer and Commercialization Office, which seeks to transfer technology into and out of NASA to benefit the space program and U.S. industry. NASA invites companies to consider licensing this technology for commercial applications.
