Full title and description

Global maritime distress and safety system (GMDSS) - Part 13: Inmarsat F77 ship earth station equipment - Operational and performance requirements, methods of testing and required test results. This International Electrotechnical Commission (IEC) standard specifies minimum operational and performance requirements, technical characteristics, test methods and required test results for INMARSAT F77 ship earth stations (SES) used for distress, safety and general radiocommunications (radiotelephony/voice) in the GMDSS context.

Abstract

IEC 61097-13:2003 defines how INMARSAT F77 ship earth station equipment must perform and be tested so that it can reliably transmit and receive distress and safety voice communications under SOLAS/GMDSS requirements. It covers operational behaviour (including distress priority handling and voice pre-emption), technical characteristics, required test methods and pass/fail criteria, and refers to related IMO and ITU performance provisions and IEC normative documents.

Scope

Specifies the minimum operational and performance requirements, technical characteristics, methods of testing and required test results for INMARSAT F77 ship earth stations (SES) intended to transmit and receive distress and safety communications, initiate and receive distress-priority calls and handle general radiotelephony as required by SOLAS and relevant IMO resolutions. The standard takes into account IMO performance standards (for example MSC.130(75) and A.888(21)), relevant ITU Radio Regulations and references IEC 60945 and IEC 61162 series for general maritime equipment requirements and digital interfaces. It also describes interaction with INMARSAT type-approval and recommends coordination of testing between INMARSAT and national approval authorities.

Key topics and requirements

• Operational and performance requirements for voice (radiotelephony) communications in GMDSS contexts (distress handling and priority).
• Technical characteristics and interfaces required of INMARSAT F77 ship earth stations, including considerations for combined installations with INMARSAT C/EGC for data and SafetyNET.
• Methods of testing and the required test results (pass/fail criteria) to demonstrate compliance with performance requirements.
• Reference to normative standards such as IEC 60945 (general maritime equipment requirements) and IEC 61162 (digital interfaces).
• Requirements and recommendations concerning INMARSAT type-approval and coordination between INMARSAT testing and national approval/testing authorities.

Typical use and users

Primary users are manufacturers of shipborne INMARSAT F77 earth stations, test laboratories, type-approval and certification bodies, maritime equipment surveyors and flag-state/port authorities responsible for GMDSS compliance and radio equipment approvals. Regulatory bodies (for example national telecommunications regulators and maritime administrations) and installers/service organisations also rely on the standard when validating equipment behaviour and conformity. In the United States the standard was incorporated by reference in FCC rules for certain maritime equipment requirements, showing its regulatory relevance while active. Note that since IEC 61097-13:2003 has been withdrawn, users should verify current applicable standards or successor documents before relying on it for approvals.

Related standards

IEC 61097-13 is part of the IEC 61097 series dealing with GMDSS ship earth stations and complements other IEC standards and IMO performance standards. Closely related and referenced documents include IEC 60945 (general maritime requirements), the IEC 61162 series (digital interfaces), other IEC 61097 parts (for example later parts covering different Inmarsat equipment such as IEC 61097-15 for FB500) and IMO/ITU performance resolutions (MSC.130(75), A.888(21), etc.). Users should consult the latest editions of those documents for current requirements.

FAQ

Q: What is this standard?

A: IEC 61097-13:2003 is an IEC International Standard that set operational and performance requirements, test methods and required test results for INMARSAT F77 ship earth station equipment intended for use in the GMDSS.

Q: What does it cover?

A: It covers minimum operational behaviour (including distress priority and voice pre-emption), technical characteristics, test procedures and pass/fail criteria for INMARSAT F77 SES, and cross-references IMO and ITU performance provisions and relevant IEC normative documents.

Q: Who typically uses it?

A: Manufacturers of INMARSAT F77 ship earth stations, test and certification laboratories, maritime administrations and approval authorities, installers and service organisations, and occasionally regulatory agencies when incorporated by reference.

Q: Is it current or superseded?

A: IEC 61097-13:2003 has been withdrawn by the IEC (withdrawal date listed as 31 December 2021 on the IEC catalogue; some national catalogues show withdrawal effective 4 January 2022). Users should consult the IEC catalogue and national standards bodies for any replacement or successor documents and for current mandatory/regulatory references.

Q: Is it part of a series?

A: Yes — it is one part of the IEC 61097 series for GMDSS ship earth stations; related parts address other INMARSAT equipment and GMDSS functions (for example later parts such as IEC 61097-15 for FB500). It also interacts with other IEC maritime series (IEC 60945, IEC 61162, etc.) and IMO/ITU performance resolutions.

Q: What are the key keywords?
