HTS-IMU11 MEMS Inertial Measurement Unit is composed of domestic high-precision MEMS gyro chip, high-precision quartz flexible accelerometer and its driving pickup circuit, temperature sensor, digital signal processing circuit and software, etc. Used to measure the 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.
Features: Applications:
• Three-axis gyro zero bias instability is 0.3°/h • Inertial navigation research and production
• Three-axis gyro angle random walk is 0.15°/√h • Guidance and control system
• Three-axis accelerometer zero bias repeatability is 0.1mg • Mobile mapping platform attitude measurement
• Three-axis accelerometer range 30g • Unmanned equipment control
• Gyro range up to 400°/s • Attitude measurement and control
• Customized service provided
