Challenges Using Modeling and Simulation in Architecture Development

A discrete event simulation was developed combining the Optical Tracking Network TeleTrak and Satellite Position Attained by RF-Keyed Tracking SPARK system into one system to track, image, and identify space objects as they pass through the space fence to increase space situational awareness for the United States Air Force. The objectives for this study are threefold model a to-be architecture for a combined TeleTrak and SPARK system to develop system requirements, determine if an optimal position for the telescope exists to return to while waiting for the next collect, and demonstrate knowledge and understanding of DOE and simulation principles and techniques. The paper explores the uses and pitfalls of modeling and simulation with this case study. While a working model remained elusive, several important observations emerged. Six recommendations are given to help others become more successful in a modeling and simulation environment along with ideas to pursue in additional research.
