High Speed Simulator - A Simulator for All Seasons

This paper will discuss the evolution of the Multimission Ground Systems Office's (MGSO) High Speed Spacecraft Simulator (HSS) development at the Jet Propulsion Laboratory. This paper will examine the evolution from both a development and operations perspective. The HSS in reality is a series of simulators capable of modeling the spacecraft and its subsystems at either the bit or functional level, depending on specific mission needs.
