Motion simulators are used to accurately reproduce roll, pitch and yaw motion in the laboratory. This helps in accelerating the time to market for new products and lowers overall R&D costs. In production, motion simulators are often used for calibration of inertial devices. The use of HardWare-In-the-Loop simulators during development of missiles can help reduce time and cost, by minimizing the number of field trials required. These simulators can also be used to ensure production quality.
