FLUXGATE MAGNETIC COMPASS --A NEW TYPE OF DIRECTION SENSOR

Fluxgate Magnetic Compass is a new type of direction sensor. It has no contact point parts, bearings and natural magnets. Therefore the compass is noted for small volume, light, high reliability, long life-span, low power loss and easy maintenance. The fluxgate magnetic compass has a wide application in the measurement of current direction, wind direction, ocea-nographic data buoy bearing and direction of underwater robots. It is an advanced and ideal direction measurement instrument widely applied at home and abroad.This paper deals with the basic operation principles, experiment circuits, main technical characteristics, the measurement data of the fluxgate magnetic compass, and the data errors of the instrument. Finally we put forwords some improvements about it.
