| Abstract: | Electronic compass has key function in some applications like unmanned aerial vehicle(UAV),portable and mobile equipment(ME),vehicle navigation and so on,where earth magnet field is used to orientate.Aiming at the proposes of raising accuracy and controlling attitude,a new three-dimensional attitude sensor--electronic compass is developed in this paper based on a Giant Magneto-resistive(GMR) unit and a patent of Magnet correction technology from SAE Magnetics(H.K.) Ltd.New electronic compass applies the performance of GMR material of rapid and sensitive response to the outside magnet field.The test data and demo results show that the electronic compass has obvious superiorities in the bulk,weight,power consumption,response speed,accuracy and so on.The availability of the electronic compass is verified too |
