Abstract

A portable detachable tracking unit for shipping containers which provides communication via satellite with a central server is provided. The tracking unit has an antenna to communicate both with the GPS satellite and a two-way satellite, a computer, a GPS receiver, a satellite transmitter, a modem and an internal power source. The tracking unit can be attached and detached from the shipping container and is can be attached to the locking bars on the doors of the shipping container. The tracking unit may have sensors for determining when it has been tampered with or detached from the shipping container and transmitting that information to the central server. The tracking unit may have a memory capable of receiving and storing geo-fencing information on the specific route to be taken to the destination with the computer being programmed to determine if the tracking unit is outside of the geo-fence or not and communicating that information to the central server. The tracking unit may have a sensor to determine whether it has been detached from a door of the shipping container and transmitting that information to the central server. A built-in tracking unit is also provided which can communicate whether a door of the shipping container has been opened or not from information supplied by a sensor.

6. The system of claim 5, in which the internal power supply of the tracking unit is provided by one of a fuel cell and battery.

7. The system of claim 1, in which the tracking unit has a memory capable of receiving and storing geo-fencing information on the specified route to its destination and the processing device is programmed to determine if the tracking unit is outside of the geo-fence and to communicate that information to the central server via the two-way satellite.

8. The system of claim 1, in which the shipping container has at least one door and at least one locking bar for locking all doors with the tracking unit being attached to the locking bars so that the locking bars can not be unlocked without first detaching the tracking unit.

9. The system of claim 1, in which the shipping container has at least one door and at least one locking bar for locking all doors with the tracking unit being attached to the locking bars by least one clamp that clamps around a locking bar that prevents the tracking unit from moving up and down on the bar and the tracking unit is also directly attached to the shipping container so that the bars can not be moved to unlock the doors without detaching the tracking unit.

10. The system of claim 8, in which the tracking unit is attached to at least one locking bar by a special fastener that can not be released without using a special tool.

11. The system of claim 1, in which the antenna in the tracking unit is located in the vertical position in relation to the surface of the earth in order to better transmit and receive communications.

12. A portable detachable tracking unit for transmitting its location via communication with a satellite to a central server, said tracking unit being capable of being attached and detached from a shipping container, said tracking unit comprising:

an antenna that is capable of communication with both a GPS satellite and a two-way satellite;

a processing device;

a GPS receiver for receiving signals from the GPS satellite;

a transmitter for transmitting information to the central server via the two-way satellite;

a modem;

a housing; and

means for attaching and detaching the tracking unit to a shipping container.

13. The portable detachable tracking unit of claim 12, which has detecting means for detecting when it has been detached from a shipping container and communicating that information via the two-way satellite to a central server.

14. The portable detachable tracking unit of claim 12, which has detecting means for detecting when it has been tampered with and communicating that information via the two-way satellite to a central server.

15. The portable detachable tracking unit of claim 12, in which the tracking unit also has a receiver for receiving communications from a two-way satellite.

16. The portable detachable tracking unit of claim 12, in which the tracking unit has an internal power supply.
