1. A system for the protection of cargo comprising:
- a tracking device to be inserted in a cargo;
said tracking device including a communication module and a dead reckoning module;
said communication module being configured to communicate wit a central server; and
an access point including a GPS receiver and a communication module configured to communicate with said tracking device communication module;
said access point being so configured as to periodically supply GPS position data to said tracking device;
wherein said tracking device is so configured that when the communication between the tracking module and the access point is lost, a last received GPS position data and dead reckoning data from said dead reckoning module are transmitted by the tracking module to the central server via said communication module of the tracking device.

Abstract
A method and system for the detection, notification and tracking of cargo theft proposes to install, inside cargo to be protected, a tracking device having communication and dead reckoning capabilities. As long as the tracking device senses that it is within a virtual fence generated by an access point, it lays dormant. When the tracking device senses that it is no longer within the virtual fence it activates the dead reckoning capabilities and communicates with a central server to supply dead reckoning data thereto. The central server processes this data and determines the current location of the cargo.

18. A system for the protection of cargo comprising:
-
cargo tracking means including communication means and dead reckoning means;
said communication means being configured to communicate with a central server; andmeans for creating a virtual fence around the cargo;
said virtual fence creating means including means for receiving GPS position data and communication means configured to communicate with said communication means of said cargo tracking means;
said virtual fence creating means being so configured as to periodically supply GPS position data to said cargo tracking means;wherein when the communication between the cargo tracking means and the virtual fence creating means is lost, a last received GPS position data and dead reckoning data from said dead reckoning means are transmitted to the central server via said cargo tracking means communication means.

19. A method for the protection of cargo comprising the acts of:
-
providing a cargo tracking device to a cargo;
the cargo tracking device including a communication module and a dead reckoning module;creating a virtual fence around an area where the cargo is located; providing GPS position data to the cargo tracking device while the cargo is within the virtual fence; when the cargo exits the virtual fence; obtaining dead reckoning data from the dead reckoning module; transmitting a last received GPS position data to a central server via the communication module of the cargo tracking device; and transmitting dead reckoning data to a central server via the communication module of the cargo tracking device. - View Dependent Claims (20, 21, 22, 23, 24, 25)
