A position is determined using GNSS (Global Navigation Satellite Systems) with an antenna assembly having a number of antennas that are oriented with different direction vectors. Antenna-received signals are supplied to an evaluation assembly, which includes GNSS receivers and an evaluation device. The antenna-received signals are detected with regard to their satellite-related signal-to-noise ratio and, in relation to each satellite, the satellite-specific signal-to-noise ratio measured values that are positively distinguished in their signal-to-noise ratio from other signal-to-noise ratio measured values relating to the same satellite are selected. A satellite-related main direction vector signal is formed from each of the direction vector signals of the antennas. The main direction vector signals are compared with the orientation vector signals that characterize the position of the respective satellites in orbit; in the event of minor deviations a position indication is given.

Method and assembly for determining position

A method is provided which protects persons in the vicinity of a high frequency (HF) field-emitting device, in particular a European train control system (ETCS) antenna of a rail vehicle. In order to be able to reliably protect persons from radiation that is detrimental to one's health, the device is held in or switched to an OFF state by an uplink for a limited period of time, the ON/OFF state being optically and/or acoustically signaled.
