Development and Demonstration of STSim, A Simulation Environment for SpaceTechnology Systems

摘要

This report documents the development of Space Technologies Simulation (STSim), asimulation environment which incorporates on-orbit space experiment assets, such as sensors, satellites, communications networks, and command centers in support of definition, acquisition, and operations phases for the Space Experiments Directorate (PLISX). The design methodology involves utilizing consistent software procedures, tools, and infrastructure in an object-oriented software environment with a flexible scope and level of fidelity to adapt individual project needs. The simulation supports both analysis and operator-in-the-loop modes of operation to allow applicability from initial concept assessment through operational phases of a program. The modular, open architecture can be extended to perform end-to end spacecraft hardware in the loop simulation and to interface with external facilities such as in wargaming simulations using standard protocols.
