MEMS Inertial Measurement Unit (MEMS IMU)

MS4000 Series

Product Overview

The MU4000 series is a highly reliable, cost-effective six-axis MEMS inertial measurement unit (IMU), suitable for applications like inertial navigation and attitude stabilization. It supports customized hardware/software configurations and the development of high-precision MEMS gyroscopes.
 

Core Process Technology

It integrates high-performance MEMS gyroscopes (for angular motion measurement) and accelerometers (for linear motion measurement) in an independent structure—both represent leading MEMS inertial device technology. Full-temperature parameter compensation (zero offset, scale factor, etc.) ensures long-term measurement accuracy; combined with overall vibration-damping and sealed design, it can accurately measure the carrier’s angular and linear motion parameters even in harsh environments, delivering a low-cost, high-reliability solution.
 

Device & Calibration Compensation Technology

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

Key Features

  1. Full-temperature compensation (full-temperature calibration from -45℃ to +80℃)
  2. 100% localized production (domestic)
  3. High performance, small size, light weight, low power consumption
  4. 1KHz high-speed sampling
  5. Resistant to harsh mechanical environments
  6. Supports over-the-air software upgrade
