  • GPS signal reception apparatus and method
    Patent number: 8896479
    Abstract: A Global Positioning System (GPS) signal reception apparatus including a GPS antenna unit, a GPS signal selection unit, and a jamming signal detection unit is provided. The GPS antenna unit includes a first-type antenna and a plurality of second-type antennas which have directivities different from each other. The GPS signal selection unit selects any one of the first-type antenna and the plurality of second-type antennas as a selected antenna. The jamming signal detection unit detects a jamming signal present in a GPS signal by analyzing the GPS signal which is received via the selected antenna.
