Abstract
A sensor arrangement measures a parameter (P) representing a position of a movable platform of a rotary parlor relative to a stationary reference point. Based on the parameter, in turn, a control unit influences the movement of the movable platform. A first transmitter unit with a first transmitter antenna is placed on the movable platform and thus moves along with the movable platform. A first radio signal emitted from the transmitter antenna contains a timing reference and uniquely identifies the first transmitter unit. At least three receiver stations are stationary placed with a respective receiver antenna located such that the first radio signal is received via line-of-sight propagation. Based on the first radio signal and respective propagation times derived from the timing reference in the first radio signal (SID), the receiver stations generate the parameter (P).
