Abstract

A system for determining the movement of a swaying structure, on which a receiver is fixedly mounted, is proposed, wherein at least three reference transmitters having known and fixed positions are provided and transmit the transmission signals received by the receiver at defined carrier frequencies. In addition, an evaluation unit is provided, which determines measured phase values from the received signals, taking into account the defined carrier frequency, wherein the distance from the reference transmitters and the changes in position of the receiver and therefore of the swaying structure can be calculated from said phase values.
