Abstract

A fiber-optic gyroscope (FOG) north finder for teaching experiment is designed and implemented. The FOG designed and implemented in this paper is a device that achieves north seeking by measuring the Earth's rotational angular velocity using a single fiber optic gyroscope. The hardware system consists of a fiber optic gyroscope, an air-floating vibration isolation platform, a rotating mechanism, a host computer, and a supporting power supply. In terms of software implementation, C # programming language is used to implement control of the rotating mechanism, communication with the gyroscope, data parsing, data acquisition and processing, and embedding commonly used two-position and four-position north seeking algorithms. The experimental results show that the fiber optic gyro north finder can well achieve the function of north seeking, has a simple and reliable structure, and is easy to implement and develop further.
