ABSTRACT:
The portable electronic device, preferably a wristwatch, includes a radiofrequency signal receiver for receiving, in particular, GPS signals via an antenna, a magnetic compass, a microprocessor data processing unit for processing data provided by the receiver and the compass, and storage means in which almanac and ephemeredes data relating to satellites is stored. The compass is arranged for provide an orientation signal to the data processing device. In this manner, the unit can control means for indicating a direction to indicate a preferred orientation for searching for satellites visible to the user in a reading position of the watch. These indicating means can be formed by the time indicating hands moved above a watch dial. The preferred orientation is calculated by the processing unit on the basis of the almanac and ephemeredes data, time data and the orientation signal.
