IEC 61108-4:2004

IEC 61108-4:2004 defines performance requirements, test methods, and required test results for shipborne DGPS and DGLONASS maritime radio beacon receiver equipment used in global navigation satellite systems. It is relevant when organizations need a technical basis for evaluating receiver performance, planning verification activities, or supporting procurement and conformity assessment. By focusing on maritime navigation and radiocommunication equipment, the document helps align engineering documentation, laboratory evaluation, and technical validation around a common compliance reference.

Overview of IEC 61108-4:2004

This document provides the primary technical reference for shipborne DGPS and DGLONASS maritime radio beacon receiver equipment, with emphasis on measurable performance criteria and repeatable test conditions. It is typically used to structure product evaluation, compare design claims against defined test outcomes, and support quality workflows for navigation-related equipment. The 1st edition, issued in 2004, is especially useful where engineering teams need a stable basis for technical review and documented assessment of receiver behavior in maritime use.

Compliance applications of IEC 61108-4:2004

IEC 61108-4:2004 is commonly consulted in marine electronics development, test laboratory planning, and procurement review for shipborne GNSS receiver equipment. It can support conformity assessment activities where DGPS and DGLONASS radio beacon reception must be checked against defined performance requirements and test results. The document is also relevant for suppliers preparing technical files, operators validating installed navigation equipment, and compliance teams organizing laboratory evaluation and product acceptance workflows.

Importance of compliance with IEC 61108-4:2004

Compliance with IEC 61108-4:2004 helps reduce technical risk by providing a structured basis for verifying receiver performance under controlled conditions. For maritime navigation equipment, that consistency matters in safety-sensitive environments where reliable positioning and operational continuity are important. The standard also supports interoperability expectations, technical validation, and procurement decisions by giving engineers and reviewers a shared framework for assessment. In practice, it can improve documentation quality and make conformity assessment preparation more efficient.
