Brief Introduction

IMU286 inertial measurement unit is a high-performance, automotive grade, small-size and shock-proof 6DoF IMU sensor. It's composed of 3-axis gyroscope and 3-axis accelerometer, and it is strictly factory calibrated at full temperature, which trims the parameter errors such as offset drift over temperature, orthogonality error, and sensitivity. This ensures the consistency of module performance, allowing it to provide continuous, stable and accurate sensor measurement values across a wide temperature range.

IMU286 enjoys high accuracy with gyro-bias instability of better than 1.2°/h,  which can be used for accurate navigation, control, and dynamic measurement of motion carriers. It offers a simple and cost-effective solution for unmanned vehicle, unmanned aircraft, unmanned surface vessel and platform stability, etc., and it has been successfully widely used in these fields.
