U3600 Mems Imu/Vru/Ahrs Sensor with Barometer, Magnetometer, High Dynamic Performance

A: Yes. Each unit undergoes rigorous factory calibration for temperature, bias, scale factor, and cross-axis errors across the full range.

A: With magnetic aiding (AHRS mode), static heading accuracy is typically 2, and dynamic drift for the U3600-B/C is 5 over one hour of typical motion.

A: Generally, no. The factory full-temperature compensation is comprehensive. Re-calibration is only advised if the mounting conditions introduce significant new stresses or thermal gradients not represented during factory test.

A: It offers a superior balance of performance, size, power, and cost (SWaP-C). While FOGs may have lower bias, this MEMS IMU provides high tactical-grade performance in a much smaller, more robust, and cost-effective package.

A: Position drift is a function of accelerometer bias. With a bias instability of 0.03 mg, velocity drift is approximately 0.1 m/s per hour, leading to position error growth over time.
