Product Details

Super Extensibility Laser Inertial Measurement Unit


Introduction

ER-IMU32 super extensibility laser inertial measurement unit is a miniaturized, medium and high precision laser inertial measurement unit. Built in 3 laser gyroscope, embedded DPsystem, two power module, accelerometer and accelerometer acquisition circuit,itcan sense the relative angular motion and line motion information of the carrier relative to inertial space.


Features

A.Free calibration

IMU level error calibration is completed, which is convenient for user engineering application.

B.Super extensibility

The installation position of the three axis accelerometer and the accelerometer acquisition circuit can be reserved.

GNSS receiver installation position and antenna interface can be reserved.

The two power module is optional. (Basic + extended power).

C.Stable performance, strong environmental adaptability

In the grade to withstand environmental requirements.


Application 

This product is applicable to all kinds of Strapdown type high precision positioning and orientation devices/GNSS inertial integrated navigation system, mobile measurement system, high-speed rail and highway measurement system and the precision of aerial photography, aerial mapping, field testing, water underground navigation and other printing equipment
