Abstract

The invention relates to a mobile terminal and its positioning satellite selection method. Disclosed are a mobile terminal capable of selecting an optimal satellite among multiple positioning satellites and a positioning satellite selection method thereof. If the DOP (Double of Precision) increases as the number of positioning satellites increases, the satellite to be used for positioning is automatically selected from the GNSS satellites based on the satellite information and the user's menu settings. This can enhance the accuracy of positioning and can reduce battery consumption. In particular, satellites used for positioning are spaced apart from each other by a prescribed distance so that the DOP is reduced, thereby improving the accuracy of positioning. Furthermore, multipath signals are reduced thereby improving the accuracy of positioning.

Description

technical field [0001] The present disclosure relates to a mobile terminal, and more particularly, to a mobile terminal capable of selecting an optimal satellite among positioning GNSS (Global Navigation Satellite System) satellites and a positioning satellite selection method thereof. Background technique [0002] Generally, a mobile terminal is configured to perform various functions. These various functions include video and voice call communication, still or moving image capture using a camera, voice storage, music file reproduction through a speaker system, image or video display, and the like. Some mobile terminals include additional functions such as playing games, and other mobile terminals may be implemented as multimedia game machines. In addition, recent mobile terminals are configured to allow users to watch videos or television programs by receiving broadcast or multicast signals. [0003] Various attempts to realize enhanced functions of mobile terminals not ...
