ASME Six Sigma.This is particularly important for maritime shipping as its radios must work seamlessly, where ever the ship travels around the world.
The BR regularly issues maritime publications that contain relevant information for ships to communicate with each other and to and from the shore. They also aid search and rescue authorities, in carrying out their duties during a distress situation. In its role as a global radio spectrum coordinator, ITU-R provides the meeting place for, among others, maritime experts from both the national administrations, international bodies and industry, to discuss and prepare, develop and maintain standards that are presented in the ITU-R Recommendations, Reports and Handbooks.
There are three publications. Published every two years, it provides information that helps to set up communication between a ship and a coast station, and also information on radio navigation aids.
Using this information the coast station may connect the ship to the local phone network or to the appropriate authorities during a distress situation, such as the coast guard. It contains a lot of information on the coast station network of each country and the services that they provide such as various modes and frequencies of communication and details of radio aids to navigation. This provides the mariner with the means to identify ships in the vicinity, including information such as their radio capabilities, size, number of persons on board, and emergency on-shore contact number.
This identification allows coast stations to contact the ship, to assist them in their navigation, or to pass on some information. This is a reference document that notes all the relevant rules or provisions from the ITU Radio Regulations that deal with maritime issues. It provides the operational procedures that should be followed by a ship station or a coast station in case of a distress situation.
It also provides all the rules and procedures of the Global Maritime Distress and Safety System GMDSS — a collection of radio communications procedures and their supporting radio systems, which support maritime safety and the rescue of ships or crew during distress situations worldwide.
It is updated on a daily basis and contains the most up to date data concerning overship stations and 2, coast stations.
It also provides links to the various standards and reports that have been developed by ITU in the maritime area and other additional helpful information. The maritime community considers the ITU maritime database to be the most complete and accurate information available as it is provided to ITU directly by the national authorities that register ships.

The choice of which Recommendations are translated is established in collaboration with the principal ITU Member Countries involved. Readers interested in such language versions should get in touch with ITU Sales and Marketing Division at the address provided in this List.
At the date when a Recommendation is approved, there remain several steps in preparing and printing the texts so the actual publication date for these Recommendations is necessarily different from the approval date. When an electronic version of a recently-approved Recommendation becomes available the text is pre-published and can be downloaded see the ITU Electronic Bookshop, page. Pre-published and superseded ITU-T Recommendations are now also available via the yearly online subscription service and the Electronic Bookshop.
A few Recommendations include software written specifically to help customers, telecommuni- cations service operators or manufacturers to test equipment, systems or networks. There is a list of available software on page. Other Recommendations describe test charts intended to test graphic communication systems.
Test charts of special quality with different resolutions may be ordered separately from the ITU Sales Service, since the specimens reproduced in those Recommendations are generally not suited for measurements. The available test charts are listed on page.
More detailed information about these products and how to order them is provided at the end of this List. For forthcoming publications, please refer regularly to the Web: www.Hatch patterns download rhino

Recommendation published in parts.Communications are essential for mariners for both routine operations and safety purposes. ETSI is responsible for producing a range of technical standards and reports concerning radio equipment and systems for maritime and inland waterways use.
Flag states are further required to carry out type approval of such equipment to ensure that it meets the appropriate safety requirements. The GMDSS uses radio communication to alert search and rescue organizations and ships in the vicinity in the case of an emergency. In addition to distress communications, the GMDSS also provides for the dissemination of general maritime safety information such as navigational and meteorological warnings and urgent information to ships. Frequencies for maritime communications and for distress and safety are generally allocated on a global basis and fixed in the International Telecommunications Union ITU Radio Regulations.
This Directive requires that the compliance of equipment with the requirements of international conventions shall be demonstrated solely in accordance with the testing standards and conformity procedures referred to in the Directive. It creates a framework for deploying and utilizing harmonized river information services to support the development of inland waterway transport with a view to strengthening its safety, efficiency and environment-friendliness, and facilitating interfaces with other modes of transport.
The SOLAS Convention requires that large passenger ships and large cargo vessels carry specific equipment for distress and safety purposes. However, similar equipment, plus other equipment not covered by SOLAS, may be fitted to other craft on a voluntary basis.Effective Communication on Board Ship
Further, all vessels may carry equipment for general communication that is not required by the SOLAS convention. The Directive relies on 'Harmonised Standards' developed by recognized European standards bodies such as ETSI which can be used to demonstrate compliance with the essential requirements of the Directive.
The REDin its basic form, has the following essential requirements:. The European Commission has also the power to introduce, by adopting delegated acts, additional requirements for particular classes of equipment, for instance to ensure access to emergency services article 3. Historically, electromagnetic compatibility EMC requirements under article 3. More recent standards for equipment include all technical requirements. ETSI's standards and reports for the maritime sector include the following equipment and systems:.

However, until the introduction of the Global Maritime Distress and Safety System GMDSS inthe way in which a message from a ship in distress was sent had changed very little from those early days; namely, a radio operator sending a message by Morse code or radiotelephone and hoping that another ship or shore station if within range would hear the call and respond.
The GMDSS has introduced new technology which has completely transformed maritime radio- communications. The new system enables a distress alert to be transmitted and received automatically over long range, with a significantly higher reliability. The system allows search and rescue authorities.
Two systems are used for broadcasting maritime safety information. In addition some national meteorological services may issue warnings and forecasts for transmission by using HF narrow band direct printing.
