Abstract

The Virtual Test Bed (VTB) is a prototype of a virtual engineering environment to study operations of current and future space vehicles, spaceports, and ranges. The High-Level Architecture (HLA) as defined by the Department of Defense (DoD), is the main environment. The VTB/HLA implementation described here represents different systems that interact in the simulation of a Space Shuttle liftoff. This example implementation displays the collaboration of a simplified version of the Space Shuttle Simulation Model and a simulation of the Launch Scrub Evaluation Model. Spaceports and ranges are complex systems. This VTB framework is a collaborative computing environment that integrates in a seamless fashion simulation models that represent the different stages in the lifecycle of a complex system to improve the complex-system visualization. A complex system is a non-linear system of systems whose interactions bring together interesting emergent properties that are very difficult to visualize and/or study by using the traditional approach of decomposition.
