Marine Data Systems have been providing innovative solutions to complex marine navigation system requirements for over 40 years. The successful merge of both Comar Systems & Marine Data Systems allows us to benefit from technical collaboration, extensive research & development and the use of a sophist...
The Automatic Identification System (AIS) is a tracking system used by ships and vessel traffic services for identifying and locating vessels by electronically exchanging data with other nearby vessels, shore stations and satellites.OceanWise
The AIS system works in the VHF maritime radio band, technically on what used to be channel 70. A full-function AIS transceiver is connected to the vessel’s navigation system and automatically transmits updated information to other users in radio range. Commercial ships, ocean-going vessels ...
Disabling Automatic Identification System (AIS): AIS is a collision avoidance system, which transmits, at a minimum, a vessel’s identification and select navigational and positional data via very high frequency (VHF) radio waves. While AIS was not specifically designed for vessel tracking, it is...
The technology was not meant for this purpose The technology behind the AIS system is now dated and can’t accommodate the high number of vessels traveling our oceans today. The system is overloaded by the high number of ships transmitting and because of this overloading signals are lost and...
It is an important system for ship positioning, communication and navigation. It has been widely usedin recent years. Using AIS system, ships can realize track association, gain information of warp and latitude, dynamic in-formation of route and so on. It plays an important role in improving ...
