1. An apparatus for distance computation, comprising:

  • a location determining device for determining a current location based on signals received from a positioning broadcast system;

    a memory for storing a coordinate of at least one reference location and at least one program for the distance computation;

    an input device for entering the coordinate of the at least one reference location, the input device operatively coupled to the memory;

    a microprocessor for calculating a distance between the current location and the at least one reference location, the microprocessor operatively coupled to the location determining device and the memory; and

    an output device operatively coupled to the microprocessor for outputting the calculated distance.
