    The system of maritime mobile communications utilizing HF radio narrow-band direct-printing telegraph (HF marine telex) is expected to see expanded use during the next several years. Experience has shown the necessity for the system to embody both automatic error correction techniques and effective means of selective calling. Use of SITOR error correction has demonstrated that error rates in the o... View full abstract»

    For a variety of reasons, communications with ships on the high seas have significantly lagged behind other communications services. For example, the maritime mobile service is practically the only service where manual Morse still constitutes a major part of the communications services. In the last few years, however, some new techniques have been developed which promise to improve maritime commun... View full abstract»

    Large-scale fitting on ships of modern radiocommunication devices such as satellite, selective calling, and other equipment for communication and radionavigation, requires an assurance of availability for real-time continuous operation under the wide range of physical stresses encountered by maritime mobile units in the hostile ocean environment. Availability is a function of the reliability/maint... View full abstract»

  • VHF maritime mobile communications: A systems approach to serving user requirements

    Publication Year: 1977, Page(s):213 - 222
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (931 KB)

    The existing international VHF maritime mobile communication system dates back to the 1947 International Radio Conference at Atlantic City, NJ. At that time, there was formal agreement on the place in the spectrum (built around the use of 156.80 MHz), and informal agreement on the use of a channel bandwidth of 100 kHz. This paper documents the events leading to the development of the maritime mobi... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (397 KB)

    The current situation for VHF/UHF marine communications in Europe is outlined, and the expectations for increased automation of that service are presented within the framework of the historical and regional factors which have shaped the current system. The degree of automation now employed, types and number of channels available, and services provided, are described for the different regions of Eu... View full abstract»

  • A study of environmental constraints in the coastal harbor radiotelephone system

    Publication Year: 1977, Page(s):226 - 238
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1078 KB)

    This paper presents a new study of the effects on communications within the coastal harbor system of such environmental factors as nonstationary signal propagation characteristics and non-stationary atmospheric noise. Propagation of signals during daylight hours is predominantly by ground-wave propagation over sea water. During the evening hours, sky-wave and ground-wave propagation takes place. T...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (748 KB)

    In order to provide for the safe and expeditious passage of maritime traffic in congested waters, the U.S. Coast Guard is authorized by the Ports and Waterways Safety Act of 1972 to establish, operate, and maintain Vessel Traffic Services (VTS) where needed. In larger areas, a VTS will generally require a communications system to enable the vessel traffic center and the participating vessels to ex... View full abstract»

    As one of the most valuable services in telecommunication service, NTT has developed a new automated maritime telephone system for public use. Calls between ship and land subscribers, or between one ship and another can be connected automatically by subscribers' dialing in the nationwide system. The new system adopts a lot of technical features such as automatic location registration, new signalin... View full abstract»

    The basic purpose of this paper is to identify the potential requirements for maritime satellite communication and position fixing as it relates to both present and future operational systems (e.g., MARISAT, INMARSAT, etc.). Particular emphasis is given to the need for position fixing and ship terminal equipment utilization in national waters, as well as other major aspects. Present MARISAT operat... View full abstract»

  • A novel concept for a satellite-based maritime search and rescue system

    Publication Year: 1977, Page(s):258 - 269
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1151 KB)

    Search and rescue (SAR) for both airborne and maritime vehicles has been an area of intense investigation for many years. Current techniques include employment of small distress transmitters which provide signals that have only a limited interception capability. This can considerably increase the search time and reduce its effectiveness. With the increased availability-existing and planned-of both... View full abstract»

    An experiment to evaluate one satellite search and rescue concept was conducted for one month around the islands of Bahama, aboard a 33-ft sailboat. The sailboat was equipped with satellite data collection equipment which provided vessel communication with an earth station by means of a simple push-button distress alarm keyer. This low-power equipment transmitted boat identification, weather data,... View full abstract»

    Future satisfaction of the electromagnetic spectrum needs of the maritime mobile service is dependent on the translation of those needs to frequency allocations. In September 1979, over 100 countries will consider all of the spectrum, and make changes to meet perceived needs of radio services, including maritime needs up to the year 2000.

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (218 KB)

    In mobile radio communications, a given correlation value between two signals received at a base station can be achieved by adjusting the antenna spacing and height; this has been experimentally verified [1], [2]. From this fact, a parameter η, defined as η=antenna height/antenna spacing is proposed as a measure of correlation for design purposes. Data from field experiments using horizo...
