Innovators at NASA's Johnson Space Center have developed a computer program for simulating diverse aspects of spacecraft operation characterized by either 3 or 6 degrees of freedom. The Spacecraft Engineering Simulation II (SES II) program provides a general framework and modular structure to solve traditional simulation problems. The innovation includes both generalized and shuttle-specific vehicle characteristics and also offers the ability to perform optimization and dispersion simulations. The technology is unique in that it contains a direct translation of the shuttle flight software from the HAL/S programming language, which was developed especially for the shuttle, to C, combining the best features of both programming languages.

Benefits

  • Integrated: Allows for rapid design of analysis products due to integration of an optimization package and a simulation environment
  • Economical: Decreases turnaround time, reducing the cost for many design and analysis applications
  • Flexible: Supports an event-based architecture in which many different types of trajectories can be simulated with the same software
  • Configurable: Realizes new vehicle simulations without re-write of the propagators, input/output functions, and error handlers

Applications

  • Next-generation launch vehicle simulations
  • Generalized simulation tools
  • Real-time simulations (pilot and hardware in the simulation loop)

Licensing and Partnering Opportunity

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.
