Abstract:
A mobile terminal capable of selecting optimum satellites among a plurality of positioning satellites and a method of selecting positioning satellites are disclosed with reference to embodiments of the present invention. If DOP (dilution of precision) increases as the number of positioning satellites increases, satellites to be used for positioning are automatically selected from GNSS satellites based on satellite information and a user's menu setting. This can enhance the accuracy of positioning and can reduce battery consumption. In particular, satellites for positioning are spaced from each other by a prescribed distance to reduce DOP, thereby enhancing the accuracy of positioning. Further, multipath signals are reduced in order to enhance the accuracy of positioning.
