Abstract
An antenna alignment device may include multiple GNSS antennas, locations and or relative orientations of which may be detected using magnetometers. The GNSS antennas may be mounted on moveable arms (e.g., at far ends of the moveable arms). Multiple magnetometers may be provided at the base of each of the moveable arms. The magnetometers may detect positions of embedded metallic objects at the bases of the corresponding moveable arms thereby determining a position of the moveable arms and the GNSS antennas mounted thereon. A processor may use the detected positions of the GNSS antennas for calculating, among other things, the azimuth of an external antenna to which the antenna alignment device is attached.
