Satellite-based AIS systems enable better, faster and efficient maritime satellite communications. Now get vessels equipped with AIS transceivers and maritime satellite Internet services to automatically broadcast information, such as ship position, speed, and navigational status, to authorities and vessel operators.
Vessel tracking and maritime intelligence have been the most significant development in navigation safety since the introduction of radar and maritime satellite communication system. Vessel tracking as the name suggests is the use of global positioning system, maritime satellite Internet service and transmission and receiving device for enabling marine and naval vessels to track, identify and monitor their and other vessels’ position, location and any other detail that might be important in stabilizing a ship’s route.
Satellite-based Automatic Identification System (AIS)
The automatic identification system (AIS) is an automatic vessel tracking system that is used for collision avoidance and better monitoring of the shipping industry. The transmission of marine traffic data using maritime very high frequency (VHF) radio is very limited, which is about 10–20 nautical miles. However, with satellite-based AIS tracking system (S-AIS), one can track the location of boats, yachts, and other naval vessels in the most remote areas of the world, such as open oceans and beyond the reach of terrestrial-based AIS system.
• In S-AIS, you get global AIS transceiver data, collected from both maritime satellite and internet-connected ships and shore-based stations. The data collected are analyzed and made available on the internet through a number of maritime satellite Internet service providers.
• Satellite-based AIS systems can contribute to maritime surveillance by detecting all vessels in specific areas of interest. It is useful for shipping industry to track their cargos and for rescue operations when officers try to co-ordinate a long-range rescue effort.
Applications of Satellite AIS systems
• Fishing Fleet Control: S-AIS systems enable national authorities to reliably and cost-effectively monitor the activities of their fishing fleets. Tracking is not limited to a certain range but fleets can be monitored from any location and in any remote area.
• Marine Traffic Services: With S-AIS, vessels get real-time traffic awareness and information about the movement of their vessel and other ships in the same area and other parts of the world. This helps in avoiding collisions at sea.
• Maritime Security and Safe Navigation: AIS enables safe navigation with maritime security. Authorities can easily identify specific vessels and their activity and create an alert during potential threats to enable more efficient use of security assets. It also aids in search and rescue operations and accident investigation. With ship position and location information transmitted over Internet, land-based shore stations can immediately send for rescue vessels for providing faster search and rescue services.
