The invention relates to a method for determining position using GNSS (Global Navigation Satellite Systems) by means of an antenna assembly (6) having a number of antennae (1-5) and a received-signal evaluation assembly (20) arranged downstream of the antenna assembly and supplied with the antennae received signals (A1-A5), the evaluation assembly containing GNSS receivers (21-25) that are connected to the antennae (1-5) and have a downstream evaluation device (26). In order to develop a method of this type in such a way that a particularly high reliability in position determining is possible with relatively low expenditure, an antenna assembly (6) is used, in which the antennae (1-5) are oriented with different direction vectors, and in relation to each detectable satellite (31-33), respective antennae received signals (A1-A5) of all antennae (1-5) are detected with regard to their satellite-related signal-to-noise ratio, thus forming satellite-specific signal-to-noise ratio measured values. From the satellite-specific signal-to-noise ratio measured values, in relation to each satellite (e.g. 31), 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 (e.g. 31) are selected. A respective satellite-related main direction vector signal is formed from each of the direction vector signals of the antennae, the satellite-specific signal-to-noise ratio measured values of which are selected, and the satellite-related main direction vector signals are compared with the orientation vector signals characterising the position of the respective satellites in orbit; in the event of minor deviations a position indication (N) is given. The invention also relates to an assembly for determining position. |
