With the proliferation of satellite-based
             defense systems and their continuing presence in
             the media it makes us more aware of our national
             defense. The United States is large, economically
             strong and a sometimes tumultuous presence in the
             global community. Although we may feel secure
             because of our superior technology and defense
             capabilities, our size and position in world
             affairs can make us a target for some countries. We
             can no longer be concerned with just our borders
             and now what comes from the skies and the sea is
             more of a threat than ever before. The United
             States government had to develop a way to counter
             these possible attacks and the Global Positioning
             The Global Positioning System was initiated in
             1973 by the Department of Defense (DOD). It was
             developed by the the DOD because at a cost of over
             twelve billion dollars the government had the
             monetary resources to achieve these idealistic
             goals. Since that time it has grown from one
             satellite used strictly by the military to
             twenty-six satellites that can be used by civilians
             also. This satellite system is used to determine
             the speed and position of an object anywhere in the
             world within one hundred meters to mere millimeters
             depending on the size and quality of user
             equipment.(GPS JOINT PROGRAM OFFICE.

             The original purpose of GPS was to maintain a
             strategic military advantage over our enemies.
             Toward the end of the arms race the targeting of
             ballistic missiles became so exact they could land
             directly on an enemy missile silo and destroy any
             missiles inside of it. The ability to take out your
             enemies missiles from great distances had a major
             effect on the balance of power. To maintain the
             balance of power the United States government had
             to develop a way to locate surfacing submarines in
             a matter of minutes anywhere in the world. Wi
