			* ARTES 20 – Implementation and validation of a Data Processing Centre as “space node” in close cooperation with and co-funding from EMSA for full data integration into SafeSeaNet services.
			* ARTES 21 phase 1 – Initial steps of the system design and implementation, including estimating the economic potential by means of a cost-benefit analysis of an Operational Demonstration Mission (ODEM), system design studies, comparative performance assessments, as well the exploration of a possible Public Private Partnership (PPP) implementation scheme for the European SAT-AIS operational system.
			* ARTES 21 phase 2 – covers the detailed design and implementation of the SAT-AIS microsatellites and payloads, and the development of innovative SAT-AIS applications and services. Following the system definition and trade-off analysis carried out in preliminary studies, a constellation of so-called microsatellites has been retained as the most cost-effective solution for providing SAT-AIS services and maintaining its viability. For this commercially-oriented project, called E-SAIL, LuxSpace will be the industrial prime contractor. In parallel, ESA is developing also a SAT-AIS payload for the forthcoming Norwegian NORSAT-1 mission, which will also fly two additional scientific payloads. Kongsberg Seatex is the prime contractor responsible for defining the technical system requirements, the development, manufacturing, assembly, test and qualification of the Novel SAT-AIS Receiver, NAIS. The operator of the NORSAT-1 satellite will be the Norwegian Space Centre (NSC). NSC will be responsible for the top-level mission requirements.

The Vessel Traffic Service receives vessels identification and location from the AIS, that by itself enables the navigators to make decisions to avoid collisions. AIS also have the ability to send Aids to navigation and Search and Rescue messages.
