Abstract
In order to find the position of a communications device, this communications device receives position data (2-7) together with associated position accuracies (8). In order to determine optimum positions (3, 5, 7), the communications device stores a number of such most recently received. position data items whose position accuracy (8) is better than a predetermined position accuracy. It is thus possible, for example in the event of an emergency, to find the location of the communications device more exactly, and define the rescue route more exactly.
