    Introduction

    ER-MIMU-14 High Performance North-seeking MEMS IMU

    Introduction
    ER-MIMU-14 is a micromechanical technology (MEMS)-based inertial measurement unit (IMU). which has the advantages of small size and light weight. Built-in three-axis gyroscope and three-axis accelerometer for measuring the three-axis angle parameters of the carrier, such as angular velocity, acceleration. The output data after error compensation (including temperature compensation, installation dislocation angle compensation, nonlinear compensation, etc.) are solved to obtain carrier attitude, velocity, displacement and other information.

    ER-MIMU-14 uses a high-precision and high-reliability MEMS accelerometer and gyroscope. It can be used for precise navigation, control, and dynamic measurements. Even in harsh environments, angular velocity and acceleration information of moving carriers can be accurately measured.

    Features
