Abstract
The present invention relates a GPS receiving apparatus having improved measurement precision as the result of selectively fetching only some of the signals transmitted by a number of satellites. The GPS receiving apparatus includes an antenna for receiving the electric waves from the satellites, an elevation-angle-computing unit for finding an elevation angle of each satellite on the basis of the electric wave received from the satellite, and a comparison unit for comparing the elevation angle with a predetermined reference elevation angle. Only electric waves transmitted by those satellites having an elevation angle greater than a predetermined reference elevation angle are selectively used for computing a position.
