What is an Electronic Compass?

An electronic compass, also called a digital compass, is a way to use the earth’s magnetic field to determine the North Pole. Known as the Luojing in ancient times, modern magnetoresistive sensors produced by advanced processing technology have provided powerful help for the digitization of compasses. Nowadays, an electronic compass processed by a magnetoresistive sensor and a fluxgate is generally used.

Although GPS has a wide range of applications in navigation, positioning, speed measurement, and orientation, its accuracy is greatly reduced or even impossible to use because its signal is often blocked by terrain and features. Especially in high-rise buildings and densely populated forest areas, the GPS signal is only 60% effective. And in the case of static, GPS can not give heading information. To compensate for this deficiency, a method of combined navigation orientation can be adopted. Electronic compass products are designed to meet the needs of users. It can effectively compensate the GPS signal to ensure that the navigation orientation information is 100% effective, even if the GPS signal is out of lock, it can work normally, so that “the star is not lost.”
