This standard pertains to “Maritime navigation and radiocommunication equipment and systems – Class B shipborne equiment of the automatic identification system (AIS) – Part 1: Carrier-sense time division multiple access (CSTDMA) techniques,” and is now available on the IEC webstore.
Description: “IEC 62287-1:2017 specifies the minimum operational and performance requirements, methods of testing and required test results for Class B shipborne automatic identification system (AIS) equipment using carrier-sense time division multiple access (CSTDMA) techniques.
This document takes into account other associated IEC International Standards and existing national standards, as applicable. It is applicable for AIS equipment used on craft that are not covered by the mandatory carriage requirement of AIS under SOLAS Chapter V. An AIS station intended to operate in receive-only mode is not considered a Class B shipborne mobile AIS station.
