    Introduction

    ER-MIMU-M02  High Performance MEMS IMU

    Introduction
    ER-MIMU-M02 is an inertial measurement unit (IMU) based on micromechanical technology (MEMS), including a built-in MEMS gyroscope with 2°/h (Allan)  bias instability and a MEMS accelerometer with 24μg (Allan) bias instability. It is used to measure the three-axis angular rate and three-axis acceleration of the carrier. Through the communication protocol, the gyroscope and accelerometer data with error compensation (including temperature compensation, installation misalignment angle compensation, nonlinear compensation, etc.) can be solved to obtain the carrier attitude, velocity, displacement and other information.  It also has a built-in three-axis magnetic sensor and air pressure sensor. The magnetometer helps with orientation and can be used to calibrate the data and orient it to the correct position. The product has high reliability and strong environmental adaptability.

    Features
    Three-axis digital gyroscope:
    Dynamic measurement range ±450º/s;
    Bias instability: 2 º/h (Allan variance);
    Angular random walk: 0.08º/√h.
    Three-axis digital accelerometer:
    Dynamic measurement range: 16g;
    Bias instability: 24μg (Allan variance);
    Speed Random Walk: 0.02m/s√h;
    High reliability: mean time between failures >20000h;
    Ensure accuracy over the full temperature range (-40°C~80°C): Built-in high-performance temperature calibration and compensation algorithm;
    Communication interface: 1 SPI, slave mode

    Application
    Space-based fields: unmanned aerial vehicles, aerial photography, agricultural plant protection, photoelectric detection stability;
    Land-based fields: vehicle navigation, vehicle satellite communications, forest and land monitoring, high-speed railway track inspection;
    Sea-based fields: hydrological measurement, waterway detection, shipboard positioning communication, unmanned surface vehicle.
