How AIS Works - Operation of AIS

Within seconds after the AIS MOB personal locator beacon easyONE-DSC is submerged into the water, the unit activates automatically and starts trasnmitting AIS and DSC alerts into vicinity of up to 7 nauticval miles.
You can also see the bright and strong red LED flare flashing which increases visibility of the victim in darkness drastically.

The term Automatic Identification System (AIS) refers to a radio system that improves the safety and guidance of vessel traffic by exchanging navigation and other vessel data.

How LUXSPACE uses AIS messages to monitor worldwide shipping traffic

At sea, space technology is used to help save lives every day: managing traffic between ships, picking up migrants and refugees in distress or spotting oil spills. The European Space Agency is once again at the forefront developing new technologies and satellites: to keep us safe at sea and to monitor the environment. Space makes a difference here on Earth and certainly at sea where there is no infrastructure.

AIS services are offered by, for example:

Operators and supervisors of the operations center (atalaia) of Praticagem da Barra do Rio Grande participated in an update course in online and face-to-face mode. They had classes on nautical charts, electronic charts (ECDIS), radars, portable pilot units (portable electronic navigation equipment) and technical English. "There is no good operation without recurrent training with good tools", says pilotage operational director, practical Bernardo Ramos

This article describes the findings from two studies that utilised an integrated systems thinking framework to understand how pilots make decisions and what factors are perceived to influence their decisions.

Understanding the fundamentals of the pivot point is highly required for understanding the alteration of the courses. Pivot point is an imaginary point on the vessel which turns on a circular path on the perimeter of vessel’s turning circle when the vessel makes a turn. The knowledge about the position of the pivot point in a manoeuvring situation provides the ship handler with the information on the geometry of motion of the ship.

In my announced sequel, the second part of GPS, it is primarily about the technical and physical operational and functional limitations to which GPS is subject. These limitations, in part, have serious implications for the accuracy of GPS, and even go as far as limiting the functionality of GPS in its functions or even making it impossible. In doing so,
