  • Patent number: 10591613
    Abstract: Relative GPS antenna alignment uses a phase shifter electrically connected to a first GPS antenna. A combiner is electrically connected to the phase shifter, the second GPS antenna and to a GPS receiver. A GPS reception signal (Sig1) emitted by the first GPS antenna is phase-shifted by the phase shifter by a phase shift (?) that can be set by way of a controller and is added by the combiner to a second GPS reception signal (Sig2) emitted by the second GPS antenna. The composite signal (Sum) thus produced is determined for at least three different phase shifts (?). On the basis of these data, the profile of the composite signal (Sum) and the relative alignment of the two GPS antennas in relation to one another is determined.
