The present invention discloses a method and a device for determining a relative alignment of a first GPS antenna (10) to a second GPS antenna (20). The device comprises the first GPS antenna (10), the second GPS antenna (20), a phase shifter (16), which is electrically connected to the first GPS antenna (10), a combiner (30), which is electrically connected to the phase shifter (16) and the second GPS antenna (20), a GPS receiver (40), which is electrically connected to the combiner (30), and a controller (50), which is electrically connected to the GPS receiver (40) and the phase shifter (16). A GPS reception signal (Sig1) emitted by the first GPS antenna (10) is phase-shifted by means of the phase shifter (16) by a phase shift (phi) that can be set by way of the controller (50) and is added by means of the combiner (30) to a second GPS reception signal (Sig2) emitted by the second GPS antenna (20). The composite signal (Sum) thus produced is determined for at least three different phase shifts (phi), and on the basis of these data the profile of the composite signal (Sum) is determined. On the basis of the profile of the composite signal (Sum), the relative alignment of the two GPS antennas (10, 20) in relation to one another is determined. |
