Title 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
Project Number 24149
Abstract/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.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
