HTS-IMU13 MEMS 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, its drive pickup circuit, temperature sensor, digital signal processing circuit, a structure and software, etc. HTS-IMU13 MEMS Inertial Measurement Unit has an excellent MEMS gyroscope performance (bias repeatability 0.3 °/h) and an accelerometer zero bias repeatability of less than 0.2 mg. 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-IMU13 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.
Features: Applications:
• Three-axis gyro zero bias instability is 0.05°/h • Inertial navigation research and production
• Three-axis gyro angle random walk is 0.02°/√h • Guidance and control system
• Three-axis accelerometer zero bias repeatability is 0.2mg • Mobile mapping platform attitude measurement
• Three-axis accelerometer range can be selected 10g/40g/80g • Unmanned equipment control
• Built-in inclinometer and 24-bit analog-to-digital conversion • Attitude measurement and control
• Support external trigger input
