Product Description

Navigation Grade MEMS IMU with 3-Axis Accelerometer & Gyroscope

Composition and Function

The inertial measurement unit integrates multiple precision sensors and processing components:

Three-axis gyroscope for angular rate measurement
Three-axis accelerometer for acceleration measurement
Three-axis tilt angle sensor (optional)
Temperature sensor for environmental compensation
Signal processing board with advanced algorithms
Robust mechanical structure
Comprehensive software suite

The system measures three-axis angular rate, acceleration, and tilt angle of the carrier, then outputs compensated data (including temperature compensation, installation misalignment compensation, and nonlinear compensation) through an RS-422 serial port using standardized communication protocols.
