QMEMS IMU




        EMCORE’s Systron Donner Inertial line of QMEMS Inertial Measurement Units (IMU) and Navi-
        INERTIAL MEASUREMENT UNITS & NAVIGATION SYSTEMS
        gation Systems (INS/GPS) deliver unprecedented performance in their class. They are designed
        for a wide variety of high-precision Commercial, Industrial, Marine and Defense Applications.
        SDI500 Tactical Grade IMU (Non-ITAR)
        The SDI500 IMU outperforms other MEMS IMUs and delivers comparable performance to older,
        costlier optical IMUs in a lower power, smaller, and lighter form factor. With 1°/hr gyro bias, 1 mg
        accelerometer bias stability and very low 0.02°/√hr Angle Random Walk (ARW) over wide tem-
        perature ranges, the SDI500 is designed to achieve the demanding performance levels required in
        sophisticated systems applications and is well-suited for use by Integrators and OEMs.

        SDI170 Tactical Grade IMU (Non-ITAR)
        EMCORE’s SDI170 IMU is designed as a performance-compatible inertial system that is form, fit, and
        functional with a legacy RLG-based IMU product, but with superior overall performance, versatility,
        and a significantly higher MTBF (Mean Time Before Failure) rating over ruggedized environments.
        The tactical performance of the SDI170 IMU is based on EMCORE’s mature, proven, dependable and
        accurate quartz MEMS inertial sensor technology in our SDI500 tactical-grade IMU.
