Description (English):

IEC 62320-3:2015 specifies the minimum operational and performance requirements, methods of testing and required test results for AIS repeater stations, compatible with the performance standards adopted by IMO Res. MSC.74 (69), annex 3, Universal AIS. It incorporates the technical characteristics of non-shipborne, fixed station AIS equipment, included in Recommendation ITU-R M.1371 and IALA Recommendation A-124. Where applicable, it also takes into account the ITU Radio Regulations. This standard takes into account other associated IEC International Standards and existing national standards, as applicable. This standard is applicable for AIS repeater stations. It does not include specifications for the display of AIS data on shore.

Abstract

Overview

IEC 62320-3:2015 specifies the minimum operational and performance requirements, test methods and required test results for shore-based Automatic Identification System (AIS) repeater stations. The standard ensures repeater stations are compatible with IMO performance standards (IMO Res. MSC.74 (69), annex 3 - Universal AIS) and incorporates technical characteristics from Recommendation ITU‑R M.1371 and IALA Recommendation A‑124. It applies specifically to non‑shipborne, fixed AIS repeater equipment and does not cover how AIS data is displayed on shore.

Key topics and technical requirements

The standard covers comprehensive functional, performance and test requirements for AIS repeater stations, including:

Functional requirements
- Types of repeater stations and repeating operation
- Synchronization and access to the VDL (VHF Data Link)
- Configuration structures and message formatting
Repeating rules and message handling
- Duplicate message filtering, content and channel filtering
- Reporting-interval and position‑based filtering
- Overload protection, RSSI‑based slot selection and message scheduling
- Repeater station identification message structure
Physical and link layer performance
- Transmitter and receiver requirements (TDMA transmitter/receiver tests)
- Frequency error, carrier power, modulation spectrum and intermodulation
- Receiver sensitivity, co‑channel/adjacent channel rejection, blocking/desensitisation
- Power consumption and environmental conditions
Test methods and required results
- Configuration and basic functional tests (including FATDMA/RATDMA/ITDMA access)
- VDL access and repetition‑rate tests, filtering behaviour verification
- Physical radio tests, spurious emissions and transceiver protection
- Normative configuration annex and informative test-area arrangements

Practical applications - who uses this standard

IEC 62320-3:2015 is used by maritime stakeholders involved in shore‑based AIS infrastructure and certification:

Manufacturers of AIS repeater stations and shore-based maritime communications equipment (for design and factory testing)
Testing and certification laboratories performing conformity, type‑approval and performance testing
Maritime administrations, harbour/port authorities and coastal surveillance operators deploying or auditing AIS repeater installations
System integrators and consultants implementing coastal VDL networks and traffic‑management systems
Regulatory bodies verifying compliance with IMO, ITU and IALA requirements

Related standards

IALA Recommendation A‑124
Other IEC standards referenced for environmental and electrical testing
