CEI EN 62287-2 PDF

This part of IEC 62287 specifies operational and performance requirements, methods of testing and required test results for Class B "SO" shipborne AIS equipment using Selforganised 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.
