A heterogeneous mobile radio arrangement comprises an antenna arrangement. There is provision for at least one shielded supply cable having a first and a second end, said supply cable being designed to supply the antenna arrangement with electric power, wherein an AISG signal and mobile radio signals are transmittable via the at least one shielded supply cable. There is provision for a first and a second IP converter and a first IP device, wherein both IP converters have a respective IP connection and at least one respective signal line connection. The first IP converter is connectable by its IP connection to a superordinate IP network, and the second IP converter is connected by its IP connection to the at least one first IP device. The signal line connections of the first and second IP converters are electrically connected by means of the shielded supply cable.

Individual pieces of position information are used to determine a location using a processor and multiple local position transmitters. The processor is supplied with at least four different navigation signals, each of which corresponds to a satellite signal on the basis of the global navigation satellite system. Each navigation signal contains information on the transmission time and the transmission location. The processor generates at least four modified navigation signals by temporally shifting navigation signals relative to one another such that the target location coordinates which can be obtained therefrom correspond to a target location on the basis of the global navigation satellite system. An analyzer then superimposes the at least four modified navigation signals in order to form a modified summation navigation signal and transmits same to the local position transmitters. The summation navigation signal is calculated individually for each local position transmitter.

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 (Sig) emitted by the first GPS antenna is phase-shifted by the phase shifter by a phase shift (&#x3c6;) that can be set by way of a controller and is added by the combiner to a second GPS reception signal (Sig) emitted by the second GPS antenna. The composite signal (Sum) thus produced is determined for at least three different phase shifts (&#x3c6;). 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.
