A marker navigation system for detecting and displaying locations of at least two reference devices, each reference device attachable to a corresponding object includes a detection device for detecting signals emitted from the at least two reference devices, a display device for displaying the locations of the at least two reference devices and/or the objects attached to the at least two reference devices based in accordance with display signals; and a data processing device. The data processing device is configured to a) calculate locations of the at least two reference devices based on the detected signals; b) determine changes in the locations of the at least two reference devices based on the calculated locations; c) check, based on the determined changes, whether the changes in the locations of the at least two reference devices can be described by at least one checking transformation that, to a predetermined extent, transforms the locations of the at least two reference devices before the change into the locations of the at least two reference devices after the change; and d) determine the display signals for displaying the locations of the at least two reference devices and/or of objects attached to the at least two reference devices as a function of the checking result.
