Research on a Combined Directional Instrument of DMC and Gyro for Vehicles

Abstract:

In the view of the disadvantages brought by DMC(digital magnetic compass) and gyro when they are used separately, a combined directional instrument composed by a 3-axes digital magnetic compass and a 3-axes MEMS gyro for vehicles is introduced, which is less influenced to the magnetic field interference and random drift. In the abnormal magnetic field, the MEMS gyro is used for correcting the heading angle of DMC. The experiment data shows that this instrument can output a stable and high-precision heading angle. It can be used to provide heading angle for vehicles.
