Product Details

High Bandwidth And Large Range FOG Inertial Measurement Unit


ER-5500 high bandwidth and large range FOG inertial measurement unitconsisting of a fiber-optic gyroscope and a quartz flexible accelerometer. The three axis closed loop fiber optic gyroscope is adopted to make it with good precision and light shape. Fiber optic inertial measurement unit product is a highly cost-effective inertial measurement equipment, and with broadband, high resolution, small zero drift, high linearity, short start-up time, strong impact resistant and anti vibration ability, small volume, low cost characteristics.


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 4KHz.

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.
