1.3 CB2 Overview
The Automatic Identification System (AIS) was designed as an aid to collision-avoidance in
the marine industry and is a significant development in navigational safety. It is now widely
used at sea to provide vessels with a live accurate picture of marine traffic in the surround
-
ing area.
The fully compliant CB2 is a Class B type AIS Transponder from ACR Electronics. Your ves-
sel information such as position, speed, and course is ascertained automatically and con-
tinuously using an internal multi-GNSS receiver and transmitted to all other AIS equipped
vessels at a maximum rate of every two seconds.
Other vessel information such as vessel name, call sign, type and dimensions as well as
the MMSI are also transmitted. This information can be uploaded to the CB2 easily by sev-
eral methods described in Section 3 of this guide. Once this information has been upload-
ed, it remains stored in the unit’s non-volatile memory even if powered down.
The CB2 also receives and interprets AIS messages from other AIS equipped vessels within
range, which can then be relayed effortlessly to other navigation devices such as chart
plotters, laptops or mobiles using the CB2’s NMEA0183, NMEA2000, USB or Wi-Fi outputs.
A multi-colour LED indicator light on the CB2 signals the on-going operational status of the
unit. This additional safety feature provides you the confidence of knowing that the CB2
has continuous AIS transmission and optimal performance.
