This part of IEC 62287 specifies operational and performance requirements, methods of testing and required test results for Class B "SO" shipborne automatic identifications system (AIS) equipment using self-organising time division multiple access (SOTDMA) techniques as described in Recommendation ITU-R M.1371. This document 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, - requires a presentation interface, - has additional reporting intervals, down to 5 s, - has two power settings, with a high level of 5 W, and - has the capability to transmit binary messages.
This document is applicable for AIS equipment used on craft that are not covered by a mandatory carriage requirement of AIS under SOLAS Chapter V.
