Space for navigation

Satellite technology has revolutionized maritime navigation and safety through automatic identification systems that track ships worldwide. Microsatellites detect radio messages broadcast by vessels equipped with automatic identification systems, providing continuous global coverage of maritime traffic that terrestrial antennas cannot achieve due to Earth's curvature. Ships of 300 tonnes or more on international voyages, cargo ships of 500 tonnes or more in local waters, and all passenger ships regardless of size are mandated by the International Maritime Organization to carry this equipment. Satellite-based systems receive these messages from vessels on the open ocean, enabling authorities to follow ship movements throughout entire voyages and providing data to maritime safety agencies for next-generation global traffic services.

Security at sea

Satellite technology also addresses security and environmental challenges at sea. Advanced radio frequency detection systems identify dark maritime activity by geolocating transmissions from vessels that disable their identification systems or never broadcast their positions, helping combat illegal fishing, human trafficking, piracy, and smuggling. These capabilities are particularly valuable for developing nations that lack resources to patrol their coastlines with aircraft or coast guards, protecting their waters from illegal fishermen who steal livelihoods from local communities. The technology enables fisheries monitoring, fleet management, environmental protection, and security monitoring for maritime and government authorities, making seas safer while supporting sustainable use of ocean resources.
