Abstract
The embodiment of the invention relates to a classifier for labeling abnormal values, a method for training and using the classifier and a navigation system. The invention relates to a classifier (100) for annotating an abnormal value (102) of a position error distribution of position information (106), wherein the classifier (100) is configured to annotate the position information (106) with an increased position error as an abnormal value (102) by using the position information (106) and a time-related boundary condition (108).
