The Army's Advanced Multispectral Simulation Test Acceptance Resource (AMSTAR) is a suite of missile Hardware-In-the-Loop (HWIL) simulation / test capabilities designed to support testing from concept through production. This paper presents the design tradeoffs that were conducted in the development of the AMSTAR sensor stimulators and the flight motion simulators. The AMSTAR facility design includes systems to stimulate each of the Millimeter Wave (MMW), Infrared (IR), and Semi-Active Laser (SAL) sensors. The flight motion simulator (FMS) performance was key to the success of the simulation but required many concessions to accommodate the design considerations for the tri-mode stimulation systems.

Advanced in inertial guidance testing place increasing demands upon accuracy, resolution, and response of motion- based test table and simulators. These test tables are typically controlled via closed-loop servomechanisms utilizing precision axis position transducers (e.g. Inductosyns, resolvers, optical encoders, etc.) to measure axis motion. A new method of acquiring data from these transducers provides greater resolution, repeatability, and accuracy of axis position measurements, enabling more precise control of the axis.
