    KGC-1 Chapter 1 Operation Manual General Chapter 1 General About GPS compass 1.1.1 Principle of GPS positioning system GPS (Global Positioning System) is a position measuring system using the artificial satellites, which consists 27 artificial satellites (4 satellites per orbit x 6 orbits plus 3 reserve satellites), orbiting the earth every 11hours 58 minutes along a circular path above the earth.

  • Page 10: For Proper Use Of Gps Compass

    From the radio wave broadcast from the GPS satellites, the KGC-1 computes own ship’s bearing in high accuracy by measuring the phase difference between two GPS antennas. Four output ports are available on the KGC-1, two for the compass bearing output, the other two for the GPS position/speed data.
