Abstract
A system for determining position comprises at least one transmitter connected to the object, at least two stationary receivers, and means for determining the phase difference with which the signal of the transmitter arrives at the two receivers. Compared to conventional radio direction finding (decca direction finding), transmission takes place only at the location of the mobile object. This has the effect that only one transmitter having very small dimensions and very low power consumption is required at the location of the mobile object. At least one pair of two stationary receivers is used for operation to determine at least one space coordinate of the object position, the measuring region for the object position being located between these receivers at this space coordinate. The position can be determined with high accuracy if the three space coordinates thereof are determined separately using at least one dedicated receiver pair.
