Abstract
A tracking system that includes equipment and methodology to determine when the tracked container is in close proximity to an aircraft. In general, the tracking device is deactivated while the aircraft container is close to or on board of the aircraft, and the tracking device is activated while the aircraft container is outside the aircraft. The tracking system includes multiple machine vision sensors associated with the tracking device positioned on the container to identify the curvature associated with the container's surroundings. Activation and deactivation of the tracking device is associated with the information transmitted and received by the tracking device, based on various features of the geographic position of the container.
