Detailed Product Description

Brief Background to AIS

AIS was designed to fulfil a need for vessels to know the position, details and navigational intentions of other vessels within VHF range for improved safety and collision avoidance. Most commercial vessels are required to fit AIS transponders by December 2004. The transponders use VHF frequencies to transmit details of their own vessel and receive details from other vessels or navigation aid within VHF range.

Introduction

SJ-8912R is a low cost, high performance AIS receive only unit, that enables the reception of
information from vessels fitted with AIS transponders at a fraction of the cost of a conventional
transponder.
The SJ-8912R installation is quick and simple, requiring only the connection to a VHF aerial (not supplied) and a computer (PC) or other device (e.g. plotter). Note these must have software that is compatible with AIS standard output to display this information.
Information received by the SJ-8912R is then transmitted via the serial data cable so that it can be displayed on compatible vessel navigation systems, vessel monitoring or other applications.
