MEMS Quartz Tactical Inertial Measurement Unit Ideal for High-Precision Applications: • • • • • • • • Precision Guided Munitions Tactical Missiles Unmanned Aerial Vehicles (UAVs) GPS-Aided Navigation Systems Torpedos Gimbal & Platform Stabilization Targeting & Pointing Systems Aircraft Precision Attitude & Heading Systems 1° Gyro Bias /hr 0.02° √hr Angle Random Walk - 5X Better Than Competition / 19 in.3 Compact Size Customer Programmable Output Data Rates Superior Quality & Reliability o 20 Year Lifetime without Calibration o Greater Than 25,000 Hr MTBF The SDI500 is a breakthrough in MEMS-based Inertial Measurement Units (IMUs) and is the first MEMS-based IMU to demonstrate true tactical grade performance with 1°/hr bias stability and very low 0.02° √hr angle random walk. The / breakthrough performance of the SDI500 IMU is based on a SDI’s proven quartz MEMS inertial sensor technology. SDI’s quartz technology enables high volume production of precisely machined sensor structures combined with the inherent large signal output and thermal stability of quartz materials. The SDI500 is a compact IMU constructed with SDI’s next generation quartz gyros, quartz accelerometers, and high speed signal processing that achieves tactical grade performance. The SDI500 IMU is rated for rugged military environments. The solid state quartz sensors and sealed IMU construction provide reliable 25,000+ hr. MTBF, and a 20 year operating and storage life. Continuous Built-in Test (BIT), configurable communications protocols, electromagnetic interference (EMI) protection, and flexible input power requirements make the SDI500 IMU easy to use in a wide range of higher order integrated system applications.
