The HTS-IMU6 Micro Inertial Measurement Unit is a high peformance, affordable, non-GPS-aided inertial measurement unit, which consists of high-precision MEMS gyrocope chip, high precision MEMS accelerometer chip and its drive pickup circuit, temperature sensor, digital signal processing circuit, a structure and software, etc. It’s used to measure three-axis angular velocity and three-axis acceleration of the carrier in real time. This IMU uses flexible connection technology, built-in full temperature compensation, installation misalignment angle compensation, nonlinear compensation and other compensation algorithms, and can output stable and reliable measurement data for users after error compensation under static, dynamic and harsh conditions.
The HTS-IMU6 has an excellent MEMS gyroscope performance (bias repeatability 0.1 °/h) and an accelerometer zero bias repeatability of less than 0.1 mg. The HTS-IMU6 inertial measurement unit is not sensitive to magnetic fields. Compared with higher cost and heavier FOG-based inertial measurment systems, it is a reliable and cost-effective inertial measurement unit.
