Maritime navigation and radiocommunication equipment and systems - Class B shipborne equipment of the automatic identification system (AIS) - Part 2: Self-organising time division multiple access (SOTDMA) techniques

Scope

IEC 62287-2:2013(E) specifies operational and performance requirements, methods of testing and required test results for Class B 'SO' shipborne AIS equipment using Self-organised TDMA (SOTDMA) techniques as described in Recommendation ITU-R M.1371. This standard takes into account other associated IEC International Standards and existing national standards, as applicable. The main differences between Class B 'CS' (IEC 62287-1) and Class B 'SO' units are that the Class B 'SO': - covers all 25 kHz channels listed in Recommendation ITU-R M.1084-5; - only uses the internal GNSS, no position sensor input is allowed; - requires use of VDL Message 17 for correction of the internal GNSS; - has a presentation interface; - has additional reporting intervals, down to 5 s; - has two power settings, with a high level of 5 W; - has the capability to transmit binary messages. It is applicable for AIS equipment used on craft that are not covered by a mandatory carriage requirement of AIS under SOLAS Chapter V.
