1. A navigation system comprising:

  • a GPS receiving module for receiving navigation messages transmitted from GPS satellites via an antenna;

    a terrestrial magnetic field sensor module for detecting a terrestrial magnetic field;

    an acceleration speed sensor for detecting an acceleration speed of a mobile object;

    a speed detecting module for detecting a travel speed of the mobile object using the acceleration speed detected by the acceleration speed sensor;

    a map storage for storing a map data; and

    a central processing unit for determining a current position of the mobile object via output signals outputted from the GPS receiving module, the terrestrial magnetism sensor module and the speed detecting module and matching the current position of the mobile object thus determined to a map data stored in the map storage and displaying the matched map data on a display unit.
