摘要: An electronic compass has a 2D magnetometer for determining two of the three components of the earth-magnetic field vector. Values for the magnitude and inclination of the field at the location of the device are given. If at least one of the body axes of the device is held horizontally in operational use, an educated guess can be made about the actual orientation of the device (e.g., heading and tilt angles) with respect to the earth. Accordingly, this compass is a very-low cost device.
