Research Topics


The ability to define, develop, and execute simulation models within the same framework at various levels of resolution using standard modeling techniques is critical in meeting Department of Defense (DoD) objectives of simulation repeatability, correction, and interoperability, and reducing cost and redundancy. Ideally, a simulation user can select a level of simulation resolution and response time that varies in range, from within the same simulation framework. The range could vary from a detailed, high resolution model that supports the design and engineering of a hardware component to an abstract, low resolution model that supports the simulation of a theater level conflict. Variable-resolution techniques that can provide this capability would support the end-to-end simulation of the system acquisition cycle.This effort identifies and prototypes variable-resolution techniques to provide a multi-level simulation modeling capability for spacecraft within the Spacecraft Simulation Toolkit (SST) framework. The SST is an advanced, flexible, development environment for the modeling and simulation of spacecraft. it is being developed by the Air Force Research Laboratory. It is an object-oriented system consisting of software objects which simulate the various systems and subsystems of the physical spacecraft.
