Abstract
The present invention includes a tracking device that is associated with a cargo container. The cargo container is used for shipping of goods and materials and is placed into transportation vessels for shipment. The tracking device includes a GPS for receiving positioning information concerning the location of the cargo container and is adapted to transmit the location of the cargo container remotely. Sensor(s) are also operatively associated with the cargo container and tracking device to sense information concerning the surroundings of the cargo container. The tracking device receives this sensor information and deactivates the tracking device when the cargo container is either inside or in proximity to the aircraft.
