Abstract

An indoor location system includes mobile transceiver units to support a manufacturing control of process courses in an industrial manufacturing of workpieces in a manufacturing plant. The indoor location system includes an analysis unit configured to determine a position of a mobile transceiver unit to be localized from runtimes of electromagnetic signals between transceiver units, and an energy consumption control unit configured to output a control signal for deactivating a localizing mode of a position signal module of at least one of the mobile transceiver units if participation of the at least one mobile transceiver unit in position determination operations is not required and to output a control signal for activating the localizing mode of the position signal module of the at least one of the mobile transceiver units from a deactivated state when participation of the at least one mobile transceiver unit in a position determination operation is required.
