Full title and description

Maritime navigation and radiocommunication equipment and systems — Global navigation satellite systems (GNSS) — Part 4: Shipborne DGPS and DGLONASS maritime radio beacon receiver equipment — Performance requirements, methods of testing and required test results. This IEC international standard sets minimum operational and performance requirements, test methods and required test results for shipborne DGPS/DGLONASS maritime radio‑beacon receivers and takes account of related IMO resolutions and IEC general maritime requirements.

Abstract

IEC 61108-4:2004 specifies performance, functional and interface requirements and associated test methods for shipborne differential GNSS (DGPS) and DGLONASS receivers intended to use maritime radio beacons. The standard is intended to ensure equipment meets performance standards not inferior to IMO resolutions and to be used together with IEC 60945 and relevant digital‑interface standards.

Scope

Specifies minimum operational and performance requirements, methods of testing and required test results for shipborne DGPS and DGLONASS maritime radio‑beacon receiver equipment to meet performance standards that are not inferior to those adopted by the International Maritime Organization (IMO). The standard takes account of IMO resolution A.694(17), is written to align with IMO resolution MSC.114(73) where applicable, and is associated with IEC 60945 general maritime equipment requirements.

Key topics and requirements

• Functional performance requirements for shipborne DGPS/DGLONASS receivers (accuracy, integrity, continuity and availability).
• Environmental, protection and EMC considerations consistent with maritime equipment practice and IEC 60945 where applicable.
• Methods of testing and required test results, including bench tests and performance verification procedures.
• Interface requirements and implementation notes for digital interfaces (references to IEC 61162 series).
• Alignment with IMO performance standards (MSC.114(73)) and referenced ITU/IMO texts where wording is identical.

Typical use and users

Used by manufacturers and designers of shipborne GNSS/DGPS and DGLONASS radio‑beacon receiver equipment, test laboratories verifying maritime equipment compliance, shipbuilders integrating navigation systems, classification societies, flag administrations and procurement bodies specifying equipment for SOLAS/IMO compliance. The document is also referenced by organizations that adopt IEC/EN national implementations.

Related standards

Closely associated with IEC 60945 (general requirements for maritime navigation and radiocommunication equipment) and references the IEC 61162 digital‑interface series (61162‑1, 61162‑2, etc.). It is part of the IEC 61108 GNSS series (other parts cover GPS, GLONASS, Galileo, BeiDou, SBAS and regional systems). National/adopted versions exist as EN/ISO adoptions (EN 61108‑4 / national standards bodies).

FAQ

Q: What is this standard?

A: IEC 61108-4:2004 is an international standard that defines minimum operational and performance requirements, testing methods and required test results for shipborne DGPS and DGLONASS maritime radio‑beacon receivers.

Q: What does it cover?

A: It covers functional performance (accuracy, integrity, continuity), environmental and interface requirements, and prescribed test procedures to demonstrate conformance. The standard is written to be consistent with IMO performance standards and to be used alongside IEC 60945 and the IEC 61162 digital‑interface standards.

Q: Who typically uses it?

A: Equipment manufacturers, test laboratories, shipyards, classification societies and maritime authorities use the standard for product design, verification, procurement and type‑approval of shipborne DGPS/DGLONASS receivers.

Q: Is it current or superseded?

A: As of its IEC publication details the 2004 edition (Edition 1.0) remains the published edition; IEC lists the publication as stable (with a maintenance/stability date shown on the IEC webstore). National bodies have adopted it as EN/UNE/CENELEC variants in 2004–2005. Users should check the IEC webstore or national standards body for any amendments, reconfirmations or withdrawals after the listed stability date.

Q: Is it part of a series?

A: Yes — IEC 61108 is a multipart series covering GNSS receiver equipment for maritime use; Part 4 is the DGPS/DGLONASS radio‑beacon receiver part and sits alongside parts for GPS, GLONASS, Galileo, BeiDou, IRNSS and SBAS where applicable.

Q: What are the key keywords?

A: DGPS, DGLONASS, maritime radio beacon, GNSS, shipborne receiver, IEC 61108, IEC 60945, IMO MSC.114(73), performance requirements, test methods.
