Abstract

Disclosed is a distance measuring system for measuring distance of a first transceiver from second transceivers, comprising the first transceiver having a first time zone, a second transceiver having a second time zone, and a control unit having a control-unit time zone. The second transceiver ascertains a time-zone relationship between the second transceiver and the first transceiver, and transmits the time-zone relationship to the control unit. The control unit receives the time-zone relationship, and ascertains, using the received time-zone relationship, a time-zone relationship between the control-unit time zone and the first transceiver. The first transceiver transmits at a defined instant in time or for a defined time period of the first time zone a distance measurement command to the second transceiver. The first transceiver transmits a measurement signal at a further defined instant in time, and the second transceiver switches from an inactive into an active receiving or measuring state.
