Radio communications and regulation of the international market by standards

The maritime connection is an important component of the global communications system. Radio communication systems and equipment enable high-speed information transfer between users. The specificity of this direction includes a lot of components, ranging from methods of measuring waves to technical characteristics of equipment. In order to ensure the correct operation of the entire system, it is necessary to have a clear regulation of this process. We invite you to get acquainted with the most important documents that provide the standards of maritime navigation and radio communications.

Maritime navigation and radiocommunication equipment and systems - Digital interfaces - Part 450: Multiple talkers and multiple listeners - Ethernet interconnection

SIST EN IEC 61162-450:2018

This standard is an important document that aims to regulate the necessary requirements that help ensure uninterrupted communications for maritime navigation. This part of IEC 61162 specifies interface requirements and methods of test for high-speed communication between shipboard navigation and radiocommunication equipment as well as between such systems and other ship systems that need to communicate with navigation and radio-communication equipment. This document is based on the application of an appropriate suite of existing international standards to provide a framework for implementing data transfer between devices on a shipboard Ethernet network. This document specifies an Ethernet-based bus type network where any listener can receive messages from any sender with the following properties. • This document includes provisions for multicast distribution of information formatted according to IEC 61162-1, for example, position fixes and other measurements, as well as provisions for transmission of general data blocks (binary file), for example between radar and VDR, and also includes provisions for multicast distribution of information formatted according to IEC 61162-3, for example, position fixes and other measurements. • This document is limited to protocols for equipment (network nodes) connected to a single Ethernet network consisting only of OSI level one or two devices and cables (Network infrastructure). • This document provides requirements only for equipment interfaces. By specifying protocols for transmission of IEC 61162-1 sentences, IEC 61162-3 PGN messages, and general binary file data, these requirements will guarantee interoperability between equipment implementing this document as well as a certain level of safe behaviour of the equipment itself. • This document permits equipment using other protocols than those specified in this document to share a network infrastructure, provided that it is supplied with interfaces that satisfy the requirements described for ONF. • This document includes provisions for filtering of the network traffic in order to limit the amount of traffic to manageable levels for each individual equipment. This document does not contain any system requirements other than the ones that can be inferred from the sum of individual equipment requirements. An associated standard, IEC 61162-460, further addresses system requirements. We advise to familiarize yourself with this document for specialists who work in the field of maritime transport. You will receive a lot of useful information that will enable you to meet international standards.

Measurement Method of a Half-Wavelength Voltage and a Chirp Parameter for Mach-Zehnder Optical Modulator in High-Frequency Radio on Fibre (RoF) Systems

SIST EN 62802:2018

Standardized measurement system makes it possible to avoid misunderstandings between different participants in the process. This standard was created for this very purpose. This document specifies measurement methods of a half-wavelength voltage and a chirp parameter applicable to MZMs in microwave and millimeter-wave RoF systems. In addition, these methods are also effective for the estimation of the intermodulation distortions and transmission performances. The methods apply for the following: – frequency range: 5 GHz to 110 GHz; – wavelength band: 0,8 μm to 2,0 μm; – electro-optic material based MZMs and their modules. Since this standard was created to unify the transfer of information between parties, we recommend that you use it in your work for achieving new goals.

Maritime navigation and radiocommunication equipment and systems - Digital interfaces - Part 1: Single talker and multiple listeners

SIST EN 61162-1:2017

If you are interested in the efficient transfer of information between maritime electronic equipment, as well as navigation, then you should pay attention to international standards in this area. IEC 61162-1:2010(E) contains the requirements for data communication between maritime electronic instruments, navigation and radiocommunication equipment when interconnected via an appropriate system. Is intended to support one-way serial data transmission from a single talker to one or more listeners. This data is in printable ASCII form and may include information such as position, speed, depth, frequency allocation, etc. Typical messages may be from about 11 to a maximum of 79 characters in length and generally require transmission no more rapidly than one message per second. For applications where a faster transmission rate is necessary, reference should be made to IEC 61162-2. The main changes with respect to the previous edition are listed below:  - certain sentences have been removed as they are not used by other standards prepared by technical committee 80;  - new sentences have been added; corrections have been made to certain sentences (ABK, BBM, DOR, FIR, SSD, TUT, and VTG);  - new fields have been added to certain sentences;  - three additional tests have been added to Annex B. Compliance with international norms specified in this standard will help you improve the quality of information transfer. We recommend that your specialists familiarize themselves with them.

Maritime navigation and radiocommunication equipment and systems - Shipborne radar - Performance requirements, methods of testing and required test results

SIST EN 62388:2014/AC:2016

Radiocommunication technologies are evolving on a daily basis and thus require the emergence of an increasingly extensive technological and regulatory framework. One of these documents is SIST EN 62388:2015/AC:2016. This International Standard specifies the minimum operational and performance requirements, methods of testing and required test results conforming to performance standards not inferior to those adopted by the IMO in Resolution MSC.192(79). (MSC.192/2) The radar installation, in addition to meeting the general requirements as set out in resolution A.694(17) and the related standard IEC 60945, should comply with the performance standards of MSC.192(79). When a requirement of this standard is different from IEC 60945, the requirement in this standard takes precedence. International standards can dramatically improve your company's bottom line.

SIST EN 62388:2014

Technological development is pushing for an increased awareness of international standards. In order to remain in the leading positions in the radio communications market, it is necessary to have in place such standards as SIST EN 62388:2014. This International Standard specifies the minimum operational and performance requirements, methods of testing and required test results conforming to performance standards not inferior to those adopted by the IMO in Resolution MSC.192(79). (MSC.192/2) The radar installation, in addition to meeting the general requirements as set out in resolution A.694(17) and the related standard IEC 60945, should comply with the performance standards of MSC.192(79). When a requirement of this standard is different from IEC 60945, the requirement in this standard takes precedence. If your company operates in the field of radio communication and related technologies, we recommend that you familiarize yourself with this document in more detail on the website.

Ocean of possibilities needs proper navigation

Maritime navigation is a complex mechanism on which the safety of the company also depends. Its effectiveness largely depends on the proper regulation of all components. The transfer of information should be strictly regulated. This will help to avoid unpleasant situations that can prevent the ship from fulfilling its purpose. Remember that your business is a ship, that can be in the ocean of possibilities in international level. We advise your specialists to study these regulations in detail and, if necessary, implement them in work.
