Satellite-AIS (S-AIS)

Satellite-AIS (S-AIS) is a maritime technology that uses satellites to detect and track vessels using the Automatic Identification System (AIS). AIS is a tracking system used on ships and by vessel traffic services for identifying and locating vessels by electronically exchanging data with other nearby ships, AIS base stations, and satellites. When satellites are used to receive AIS signals, the system is called Satellite-AIS or S-AIS. Unlike traditional AIS which has a range limitation due to the curvature of the Earth, S-AIS can provide global coverage, allowing for the tracking of vessels in remote areas such as the open ocean or polar regions. S-AIS data can be used for a variety of applications including maritime domain awareness, search and rescue operations, and maritime intelligence. It provides real-time information such as a vessel's identity, type, position, course, speed, navigational status and other safety-related information.
