The electronic compass, also known as digital compass, is a method that modern people use electronic technology making earth's magnetic field to set the North Pole. Modern magneto-resistive sensors uses advanced processing techniques and provides powerful help for compass electronics. Known in ancient times as the compass, Nowadays, electronic compasses made of magnetoresistive sensors and fluxgates are generally used. The electronic compass can be divided into a planar electronic compass and a three-dimensional electronic compass.
Digital compass is widely used in horizontal hole and vertical hole measurement, underwater exploration, aircraft navigation, scientific research, education and training, building positioning, equipment maintenance, navigation system, simulation system, GPS backup, car compass, virtual reality.
