SEA VESSEL TAGGING APPARATUS AND SYSTEM
First Claim
1. A sea vessel tagging and identification device comprising:
- a radio receiver for receiving an underwater electromagnetic trigger signal transmitted by an underwater beacon;
an acoustic transmitter for transmitting an acoustic identification signal to a remote underwater acoustic receiver;
wherein during operation, said acoustic transmitter transmits said identification signal on reception of said underwater electromagnetic trigger signal by said radio receiver.

Abstract
The present invention discloses a tagging and identification device and system for tracking and monitoring sea vessels as they enter sea ports, estuaries and/or other channels. The tagging device of the present invention comprises a receiver, for receiving an underwater electromagnetic signal transmitted by an underwater beacon. An acoustic transmitter is provided for transmitting an identification signal to an acoustic receiver deployed nearby. The acoustic identification signal is transmitted after an electromagnetic trigger signal is received from the underwater beacon. The tagging and device may further comprise a memory device which can store data relating to position and time of the see vessel to which it is attached. The tagging and identification device of the present invention is covert, compact and is capable of extended active deployment without replenishment of batteries etc. The identification tagging device and system of the present invention is capable of being deployed for tracking the location of sea vessels without the knowledge of the vessel crew. The system of the present invention allows third a third party to monitor suspect vessels as they enter specific ports or estuaries.
