Abstract: A method and a safety system for localizing at least two objects has a control and evaluation unit, and at least one radio location system. The radio location system has at least three arranged radio stations, wherein at least two respective radio transponders are arranged at the objects. The two radio transponders are arranged spaced apart from one another. Position data of the radio transponders and thus position data of the objects can be determined by means of the radio location system, and the position data can be transmitted from the radio station of the radio location system to the control and evaluation unit and/or the position data can be transmitted from the radio transponder to the control and evaluation unit. The control and evaluation unit is configured to cyclically detect and compare the position data of the radio transponders.
