What exactly is an AIS transponder system?
AIS (Automatic Identification System) is a system making it possible to identify and receive information about all vessels within VHF coverage.

How does an AIS transponder system work?
The AIS uses two VHF channels, where information about a vessels identity, position, course, speed and heading is transmitted with a high frequency. The size, cargo and destination (if available) are also provided and is presented to the user through a electronic display system. The AIS equipment works autonomously and is self-organising its transmissions.

Why use an AIS transponder system?
The AIS transponder can be helpful in several types of vessels. The system is used in search and rescue (SAR) helicopters and increases the surveillance capacity for the coastguard. The AIS transponder system also benefits environmental protection and helps to eliminate the problem with radar range. Another great advantage with the AIS transponder system is the national security monitoring. Today AIS transponder systems are used worldwide in SAR-, military- and icebreaker operations.
