Ta del standarda IEC 62287 določa zahteve za delovanje in zmogljivost, metode preskušanja ter zahtevane rezultate preskusov za ladijsko opremo razreda B avtomatičnega identifikacijskega sistema »SO« (AIS), ki uporablja tehnike samoorganiziranega časovno porazdeljenega sodostopa (SOTDMA), kakor so opisane v priporočilu ITU-R M.1371. Ta dokument upošteva druge povezane mednarodne standarde IEC in obstoječe nacionalne standarde, kakor je primerno.
Glavna razlika med enotami razreda B »CS« (IEC 62287-1) in »SO« je, da razred B »SO«:
• zajema vse 25-kHz kanale, navedene v priporočilu ITU-R M.1084-5,
• uporablja samo notranji GNSS – vhod senzorja položaja ni dovoljen,
• predvideva uporabo VDL Message 17 za popravek notranjega GNSS,
• zahteva predstavitveni vmesnik,
• vključuje dodatne intervale poročanja – najmanj 5 s,
• omogoča dve nastavitvi napajanja, pri čemer je višja 5 W, in
• omogoča zmogljivost prenosa binarnih sporočil.
Ta dokument za vso opremo avtomatičnega identifikacijskega sistema v uporabi na ladji, ki je ne zajema obvezna zahteva za prevoz za avtomatične identifikacijske sisteme v 5. delu Mednarodne konvencije o varstvu človeškega življenja na morju.

Overview
EN 62287-2:2017 (identical to IEC 62287-2:2017) specifies operational and performance requirements, methods of testing and required test results for Class B "SO" shipborne AIS equipment using self-organising time division multiple access (SOTDMA) techniques. The standard covers functionality, environmental and EMC requirements, internal GNSS position reporting, link and network layer behaviour, user interfaces, and test conditions. A key technical change in this edition is the introduction of transmission of Message 27 on channels 75 and 76 for long-range broadcast applications. EN 62287-2:2017 is maintained by CLC/CENELEC and references ITU‑R M.1371 and related IEC maritime standards.
Key topics and technical requirements
- SOTDMA medium access: Defines link-layer procedures for Class B "SO" AIS transponders to self-organise TDMA slots according to ITU‑R M.1371.
- Performance and operational requirements: Includes message types, reporting intervals, identity and static data handling, and short safety-related messaging.
- GNSS integration: Requirements for internal position receivers used for position reporting and associated fallback conditions.
- Physical and radio characteristics: Transmitter and receiver requirements, operating frequency channels, and long-range broadcast capability (Message 27 on channels 75/76).
- Protocol stack: Coverage of physical layer, link sub-layers (MAC, DLS, LME), network and transport layers, and presentation interface.
- Safety, QA and documentation: Mandatory manuals, marking, built-in integrity tests (BIIT), transmitter shutdown procedures, and protection from invalid control commands.
- Testing and environmental conditions: Prescribes methods for performance tests, EMC, power-supply (brown out), vibration, shock and test signal conditions.
Applications
- Vessel tracking and identification for collision avoidance and situational awareness
- Long-range AIS broadcasting for offshore vessels and search & rescue coordination
- Integration with bridge systems, ECDIS, VTS (Vessel Traffic Services) and shore-based monitoring

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
