Tideland’s Informer V03 AISsystem is the first designed specifically for installation on aids to navigation, and capable of full integration into port or coastal AIS networks. It broadcasts its name, type and MMSI number, virtual target flag and, in the case of moored aids, a warning if it goes off station. This information is received by all AIS fitted vessels as well as land stations and is displayed graphically and in real time on any AIS enabled electronic chart or radar screen.

The Informer V03 Type 3 units have been installed on the two fairway buoys and the first pair of lateral mark buoys that mark the initial southern entry to Barcelona Port. There has been no need to enlarge the buoy solar power system, thanks to Informer's low consumption and the generous solar power provision existing on the buoys.

Barcelona, one of Spain’s busiest ports, plans to install a new AIS base station in the future. Consequently, the port authorities chose Tideland's Informer V03 Type 3, a transmit and receive unit, which allows integration into a high AIS traffic environment without the need for slot management by a base station.
