    ER-FIMU-5500 High Bandwidth and Large Range FOG IMU 


    ER-FIMU-5500 High Bandwidth and Large Range FOG IMU is composed of fiber optic gyroscope and quartz flexible accelerometer. The product adopts three-axis closed-loop fiber optic gyroscope, which has good accuracy and light appearance. The optical fiber inertial measurement unit product is a cost-effective inertial measurement device, which has the characteristics of broadband, high resolution, low zero drift, high linearity, short start-up time, strong shock and vibration resistance, small size and low cost.


    High bandwidth, large range, low power consumption and small volume;

    The response time is short and the data update rate can be as high as 4 KHz;

    With ARM processor, the navigation algorithm can be designed according to the user’s needs;

    The sensor data are calibrated and temperature compensated, and the whole temperature performance is stable.
