Dublin Bay Digital Diamond Testbed
The Dublin Bay Digital Diamond (DBDD) is an e-navigation and communications proof of concept test bed in Dublin Bay
The Diamond serves as an opportunity for users across the maritime sector to explore the potential of these services. The Diamond’s primary stations are at Kish Lighthouse, Baily Lighthouse, Dublin Port and CIL Dun Laoghaire. These locations can provide effective digital communications coverage across Dublin bay and its approaches. The goal of the project is to demonstrate and develop the capabilities of the CIL e-navigation and communications networks.
