Above deck unit for automatic identification system
First Claim
1. An above deck unit for an automatic identification system contained in shipborne facilities installed on a ship, the shipborne facilities being part of the automatic identification system, comprising:
- a container, a messaging antenna mounted on the surface of said container and used for transmitting and receiving a message, said message being communicated automatically in a wireless manner between ships or between a ship and a coast station, said message containing static information, such as a name of a ship, and dynamic information, such as a current position of the ship, a radio circuit stored in said container and using said messaging antenna for transmitting and receiving said message, said container and said radio circuit being externally installed on the ship so as to allow said transmitting and receiving of said message to and from another ship or a coast station, and a controller installed in said container or installed externally, independently of said container for controlling said transmitting and receiving operations of said radio circuit, said controller supplying information to be contained in said message to the other ship or the coast station to said radio circuit, thereby transmitting said message from said radio circuit, said controller outputting information contained in said message received by said radio circuit from the other ship or the coast station through an inboard transmission path, thereby supplying information to be provided to a crew to an interface means for the crew connected via said inboard transmission path.

Abstract
An above deck unit for an AIS (automatic identification system) is externally installed on a ship. The above deck unit includes a radio circuit and an associated antenna for transmitting and receiving a message, a position detector and an associated antenna, associated controller and power supply, and a container for storing these elements. An inboard transmission path, e.g., a cable, connects the outdoor unit for the AIS and an AIS display serving as an interface means for the crew. A signal to be transmitted through the inboard transmission path is a processed, for example, an amplified signal, rather than an unprocessed output of a VHF antenna. Therefore, problems of signal loss or degradation along the inboard transmission path are unlikely to occur. Because the unit is incorporated within a single container, it can easily be installed and transferred. With this antenna complex, it is also possible to suppress interference between antennas.

17. A waterborne complementary unit for an automatic identification system installed on a waterborne structure arranged fixedly in a water area or a floating object floating on the water, comprising:
-
a container, a messaging antenna mounted on the surface of said container and used for transmitting and receiving a message, a radio circuit stored in said container and using said messaging antenna for automatically transmitting and receiving said message to and from a ship or a coast station, and a controller for controlling said transmitting and receiving operations of said radio circuit, said controller supplying information to be contained in said message destined for the ship or the coast station to said radio circuit, wherein said waterborne complementary unit for the automatic identification system transmits the static or the dynamic information, such as the current position, concerning said waterborne structure or said floating object by transmitting said message.
