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.

Benefits

  • Accurate: Provides enhanced time scale modeling
  • Flexible: Supports multiple related coordinate systems and frame-specific vehicle state integration
  • Improved: Permits more accurate modeling of multiple time scales since it permits time scales to have nonlinear dependence
  • Efficient: Features a configurable hierarchical organizational structure to manage and use coordinate systems
  • Extensible: Supports planetary, inter-planetary, and multi-planetary simulations
  • User-friendly: Offers clearer interfaces for external systems model integration

Applications

  • Governmental and commercial organizations involved in space exploration
