Researchers at NASA’s Johnson Space Center have developed simulation software designed to support the integration of various modeling and simulation programs across various analysis and testing environments. This architecture was designed to support a wide variety of guidance, navigation, and control (GN&C) engineering analyses, including requirements assessments, flight software prototyping, design trades, hardware in the loop testing, and operator in the loop evaluations for NASA’s Crew Exploration Vehicle (CEV). A key innovation of the Advanced NASA Technology Architecture for Exploration Studies (ANTARES) design is its ability to integrate existing but distributed simulation environments and modeling systems into a single architecture capable of supporting a wide variety of analyses and testing environments. The technology includes the collection and integration of models across all flight regimes, including ascent, orbit, and entry. A recent re-architecture allows for running multiple flight software (FSW) strings simultaneously, providing an easy comparison of multiple proposed FSW algorithm prototypes. This software may be released for U.S. Government purposes only.

Benefits

• Flexible: Supports collaborative model development that can be used in many analysis and testing environments
• Comprehensive: Includes end-to-end vehicle simulation for ascent, on-orbit, and entry components
• Efficient: Supports code reuse where applicable, allowing domain experts from various fields to contribute to the model library
• Collaborative: Fosters cooperation among many groups, including GN&C engineers, simulation and graphics tool developers, mission operations flight designers, and human factors groups designing next-generation operator interfaces

Applications

• Integrated modeling and simulation for the design of new spacecraft
