The HTS-IMU4 Inertial measurement unit is a small, non-GPS-aided inertial measurement unit weighing only 55 grams. It is suitable for a variety of commercial and military guidance and navigation applications. It has the same gyro performance as the HTS-E3/1A gyroscope module (alternative STIM210 Sensonor) and an accelerometer zero bias repeatability of less than 0.2 mg. The HTS-IMU4 inertial measurement unit has 3 built-in inclinometers to ensure accurate system leveling and provides an external synchronization signal input. The IMU (inertial measurement unit) is temperature compensated over a wide operating range, and all axes are mechanically and electrically aligned relative to the package reference plane. The HTS-IMU4 inertial measurement unit is not sensitive to magnetic fields. For higher-priced and heavier FOG-based inertial measurment systems, it is a relatively reliable, cost-effective inertial measurement unit. Its output format, sampling rate, filter settings, and data packet content can be set by the customer.
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
