1. A method for determining and displaying a position of a target relative to a relative position determining first GPS device and being responsive to data communicated from an orbiting Global Positioning System (GPS) satellite network, said method comprising the steps of:

  • a) determining a geographical location of the first GPS device by receiving and processing GPS signals from the orbiting GPS satellites;

    b) correlating the geographical location of the first GPS device to be coincident with a point of origin on a visual display means;

    c) receiving and processing telemetry data containing a geographical location of the target;

    d) calculating a relative position of the target relative to the first GPS device so as to provide an approximate direction of travel and distance to the target from the first GPS device; and

    e) graphically displaying on the visual display means of the first GPS device the relative position of the target with respect to

         1) any physical orientation of the visual display means of the first GPS device which is in a generally horizontal plane relative to the earth, and

         2) the point of origin on the visual display means of the fist GPS device, and wherein the relative direction of the target is displayed utilizing at least a direction indicating symbol to portray the relative position information.
