Introduction

ER-MIMU-10 IMU/VRU/AHRS

Introduction
The ER-MIMU-10 inertial sensing system integrates industrial-grade MEMS gyroscope and accelerometer, which can output 3D angular velocity, acceleration, magnetic field information, and fused 3D azimuth angles.When connected to a satellite navigation (GNSS) signal, fused position and velocity information can be output. ER-MIMU-10 includes ER-MIMU-10U Inertial Measurement Unit (IMU), ER-MIMU-10V Vertical Reference System (VRU), ER-MIMU-10A Attitude Reference System (AHRS)

The ER-MIMU-10 is embedded with multi-sensor fusion algorithm, which has been calibrated at the factory in all temperature ranges to ensure the excellent performance of the system in harsh environments. The compact design of the ER-MIMU-10 makes it easy for customers to integrate applications and shorten the development cycle.

The ER-MIMU-10 has a dynamic attitude detection accuracy of 0.3° and provides a stable, low-drift relative heading output and a drift-free absolute heading output. It can meet the attitude, direction stability control, positioning and navigation needs of various carriers in complex and harsh application environments.

Application
Robots, unmanned vehicles
Construction machinery, intelligent agricultural machinery
Satcom on the move/Communication in Moving
