According with International Maritime Organization (IMO), Shipping is the most international of all the world's great industries. In fact a huge number of vessels moves around the world each day, making the efficiency, safety and optimization of marine transportation key issues.
GNSS technology will be fundamental for bringing innovation and progress in navigation and many other marine activities such as fishing, oceanography and oil and gas exploitation. Satellite navigation benefits all maritime applications, including leisure boats, commercial vessels, and unregulated and Safety of Life at Sea (SOLAS) regulated ships. Each application will take advantage of the new characteristics offered by GNSS augmentation: increased accuracy and integrity, certified services and high availability.[1]
GNSS will be used in every phase of marine navigation: ocean, coastal, port approach and port manoeuvres, under all weather conditions.[2]
Overview of Maritime Applications
GNSS is used mainly in maritime en route navigation and in support to the AIS and VTS systems which are maritime traffic collision and traffic control mechanisms. In maritime en route navigation there are two categories of applications, the chart plotters receivers and fish finder applications.
Besides the above mentioned applications, there are several other use of GNSS in marine applications, such as:[3]
- Observing the changes of sea level,
- Dredging operations,
- Locating wrecks,
- Laying pipe lines,
- Salvage of sinking vessels,
- Dynamic Positioning,
- Positioning of oil rigs and
- Fixing of Satellite sea launch platforms.
Nowadays, ship navigation casualties and incidents can result in serious loss of life and pollution of the marine environment as modern ship can carry over 5,000 people and over 500,000 tons of petroleum.[4] A wide variety of vessels moves around the world each day. The efficiency, safety and optimization of marine transportation are key issues.[1]
Due to the presented reasons, GNSS shall be adopted as a marine navigation tool because it will provide a reliable and short cost solution, allowing interoperability across navigational areas and with great impact in safety and commercial benefits, for all maritime purposes, including leisure boats, commercial vessels, unregulated and Safety of Life at Sea (SOLAS) regulated ships.[1]

AIS/VTS
The Automatic Identification System (AIS) is perhaps the biggest technological advance in maritime navigation, since the introduction of radar. The service is a shipboard broadcast system that acts like a transponder, operating in the VHF maritime band and transmitting real time information of the vessel, in a similar manner as the ADS-B. [5] As well as the ADS-B, the AIS relies on GNSS as primary data source, to obtain vessels real-time position.
The Vessel Traffic Service (VTS) provides active monitoring and navigational advice for vessels in particularly confined and busy waterways.[5] Usually the VTS integrates in a command and control room, information from sources such as radar, AIS and closed circuit television sites.
Detailed information about AIS/VTS can be found here.
