Description

MF3 North Finder – Rapid and Autonomous True North Determination System

Product Overview

The MF3 North Finder is an electromechanical integrated system designed for rapid and autonomous true north determination. It calculates the angle between the gyroscope's main axis and Earth's true north by tracking Earth's rotation angular velocity, providing precise azimuth information for carriers.
