MEMS IMU-B001A/B02A/B05A | Tactical-Grade High-Precision Inertial Measurement Unit

MEMS INU6000

Product Overview

The MEMS IMU-B001A/B02A/B05A is a highly reliable, cost-effective six-axis MEMS inertial measurement unit (IMU), suitable for applications such as inertial navigation and attitude stabilization. It supports customized hardware and software configurations, can be upgraded to a customized inertial navigation system, and can also connect to other devices to achieve integrated navigation.
 

Core Process Technology

It integrates high-performance MEMS gyroscopes and accelerometers in an independent structure, representing the leading level of MEMS inertial devices. The module features built-in full-temperature parameter compensation (zero offset, scale factor, etc.) and anti-shock/vibration design, enabling accurate measurement even in harsh environments and delivering a low-cost, high-reliability solution.
 

High-Precision Device Manufacturing & System Calibration Technology

Leveraging accumulated core technologies, the system adopts high-speed sampling, full-temperature static error compensation (zero offset, installation error, etc.), and dynamic error compensation (coning error) to ensure high performance.
