Device and method for tracking a subject using satellite positioning data

Abstract

A device disposed on a subject to maintain the subject within a containment zone and track the subject if the subject exits the containment zone. The device includes a positioning unit for generating position data including satellite positioning data. There is a processor unit to determine from the position data if the subject is inside or outside of the containment zone. The processor unit operates in a containment mode when the subject is inside the containment zone and in a tracking mode when the subject exits the containment zone. A correction unit issues a stimulus when the subject exits the containment zone and terminates the stimulus when the processor unit enters the tracking mode from the containment mode. There is a communication unit which transmits an alert to an electronic device of an operator when the processor unit transitions from the containment to tracking mode.
