For hundreds of years now ships have capitalized on the field generated by the earth’s magnetic poles to navigate around the world. The crude compass has evolved into a magnetic sensing device commonly know as a magnetometer. This directional tool has been used very successfully as a heading and orientation sensor on dynamic platforms. Magnetometers are sensor that detect both the signal and magnitude of the earth field as a voltage output. Using solid-state magnetic sensors and a tilt sensor , a low coast compass system can be realized. This paper covers part of the design vessel heading control systems. The paper presents the principle and design of magnetic sensors in direction control. HMR 3300 is a 3-axial magnetometer, that uses the RS232 converter. This paper presents the design method of the RS232 signal generator based on the programming language Visual C++. And it can generate different basic signals and chirp signals. It has a variety of functions including display of the signal for heading and linking another vessel electrical system .
