Abstract
A method for detecting anomalies in a positioning system comprises receiving, for a plurality of locator devices (ANC, ANC, ANC, ANC), respective location indicators associated with at least one mobile device (TG, TG, TG), determining a position of the at least one mobile device (TG, TG, TG) based on the received location indicators, acquiring, for at least one of the location indicators received, a confidence indicator associated with the at least one of the location indicators, determining, for each acquired confidence indicator, whether a confidence criterion is met, and storing an anomaly indicator in an anomaly cache, if the confidence criterion is not met, wherein each anomaly indicator is associated with the locator device, for which the location indicator is received; and generating an anomaly alert message for at least one of the locator devices based on an evaluation of the anomaly indicators that are stored for the at least one of the locator devices.
