Abstract

A method to define a three-dimensional geographical zone that is utilized with a movable entity having at least one attached transponder is disclosed. The method comprises allowing a user to enter at least one waypoint, and loading at least one waypoint on at least one transponder. In one or more embodiments, a waypoint is defined by a geographical coordinate and a radius. The geographical coordinate is represented by a latitude value, a longitude value, and an elevation value. And, the radius is represented by a distance magnitude. In some embodiments, the method further comprises regulating the movable entity by monitoring, controlling, and/or visualizing the movement, non-movement, or position of the movable entity. The transponder determines whether the transponder is located inside the three-dimensional geographical zone by obtaining global positioning coordinates, and calculating whether or not the global positioning coordinates are located inside at least one waypoint.
