Abstract
A device for checking the consistency of a positioning includes: a transmitter, a receiver, a time measuring unit, a distance determining module and a check module. The transmitter emits at least one signal, and the receiver receives at least four response signals from at least four different response elements. A response element receives the at least one signal and, upon receipt, emits a response signal. The time measuring unit determines, for each response signal, a total delay time from a transmission time of the signal and a reception time of the respective signal. The distance determination module determines a distance to the respective response element based on each total delay time, and the check module performs a consistency check of a determination of a position based on distances to the different response elements. With the device, erroneous distance values may be detected in ground-based positioning systems.
