标准摘要
[中文适用范围]： “IEC 62287 的这一部分规定了使用 ITU-R M.1371 建议书中所述的自组织 TDMA (SOTDMA) 技术的 B 类“SO”船载 AIS 设备的操作和性能要求@测试方法和所需的测试结果。本标准考虑到其他相关的 IEC 国际标准和现有国家标准@（如适用）。B 类“CS”(IEC 62287-1) 和 B 类“SO”单位之间的主要区别是 B 类“SO”单位“”： ? 覆盖 ITU-R M.1084-5 建议书中列出的所有 25 kHz 信道； ? 仅使用内部 GNSS@，不允许位置传感器输入； ? 需要使用 VDL 消息 17 来校正内部 GNSS； ?具有演示接口； 具有额外的报告间隔@低至5秒； 具有两种功率设置@，高电平为5 W； 具有传输二进制消息的能力。不属于 SOLAS 第五章中 AIS 强制运输要求的范围。” [外文原描述]： IEC 62287-2:2013 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.
