Abstract

A method for the determining a position of at least one measurement object equipped with a mobile station having a receiver includes employing at least four reference objects having a base station and a transmitter, wherein a first reference object of the at least four reference objects has a mobile station with a receiver and simultaneously acts as a measurement object. The base station and the mobile station are structurally combined. The reference objects initially have a known position that can change. The transmitters of the base stations transmit signals and the mobile stations receive signals. The method additionally includes emitting, by at least two transmitters of base stations, periodic signals of different frequencies at mutually defined time intervals, wherein these frequencies are closely adjacent.
