DANSK DSF/FPREN 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 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.
