Abstract:Accurate heading information is crucial for many mobile services such as navigation, autonomous vehicles, and robot applications. The standard way to obtain heading information is by using a tri-axis magnetometer, which can measure the signal intensity of the magnetic field in three orthogonal directions. However, a magnetometer is known to be highly susceptible to environmental interferences that may easily generate error up to thousands of nano-tesla, causing unacceptable errors (e.g., 40 degrees) in the dir… Show more
