Automatic Responder Service

A new generation of technology stemming from increased global demands for improved ship security can also improve safety for recreational boaters. Changes mandated by the International Maritime Organization (IMO) and the Marine Transportation Safety Act in the United States require larger, commercial vessels to use Automatic Identification System (AIS) equipment while underway. Information broadcast by commercial AIS transponders is available to recreational boaters through the purchase of modestly priced receivers that can interface with digital chartplotters installed on many boats.

What Kind of Information Can AIS Provide? - A chartplotter display or a shipboard radar display overlaid with electric chart data can mark the positions of every noteworthy vessel within range of the AIS receiver. Each vessel displayed through AIS will have its speed, heading, name, radio call sign, Maritime Mobile Service Identity (MMSI) number, course over ground, rate of turn and much more information available with the click of a button. This represents a remarkable wealth of data previously available only to Coast Guard Vessel Traffic Service (VTS) operators.
