    While there are some 250 000 civil aircraft in the world, only about 500 of them are in transoceanic service and therefore prime candidates for the systems described in this special issue. The rest mainly depend on short-range systems treated elsewhere. However, there are 25 000 ocean-going merchant ships. The article discusses some nontechnical factors that influence the choice of systems for the... View full abstract»

    A survey is provided of the many new developments in the Loran-C radio navigation system in recent years; in system coverage, capabilities, and applications. These have come about as a result of new station installations and modern electronics. System techniques are reviewed and uqpdated, information on radio propagation is summarized, and micropcocessor-based receiver developments and solid-state... View full abstract»

    Omega is a very-long-range, very-low-frequency (VLF) radio navigation system which now provides continuous global coverage for ships and aircraft. The final eighth station was completed in Australia in 1982. Coverage is not only global but is also redundant with more than the minimum required number of signals usually available in most locations. The system is in general use in both the marine and...

    Inertial Navigation Systems have found universal application both militarily and commercially. They are self-contained, nonradiating, nonjammable, and sufficiently accurate to meet the requirements of users in a most satisfactory manner. An overview of inertial navigation is provided, followed by several sections detailing a specific, but different mechanization approach. A Ring Laser Gyro (RLG) b... View full abstract»

    With the award of one of the first multiyear procurements to be authorized by the Congress, the Department of Defense celebrates the tenth anniversary of a major Joint-Service / Agency program that promises to revolutionize the art and science of navigation. This contract, totaling 1.17 billion dollars, will result in delivery by the end of this decade of 28 satellites that are to become the heart... View full abstract»

    After a review of the present GPS program status and its announced schedule, a change of perspective to the future is attempted. Well before the year 2000, widespread civil use is predicted, spurred by the availability of simple and reliable $500 equipment for applications including hiking and automobile driving. The purpose is to focus on today's system issues of L2access, user charge ... View full abstract»

    This paper will discuss the interdependence between navigation and Precise Time and Time Interval (PTTI) systems. The modern role that navigation systems play in the field of timekeeping is shown through examples of how Omega, Loran-C, TRANSIT, and the Global Positioning System (GPS) are utilized by the PTTI community.

    Navigation has always relied on data collection, processing, and computation. The aplication of modern computers and microprocessors to this field dramatically highlights the interdependance. Nevertheless, there is much to be accomplished to close a "processing gap" that has opened up, especially in the field of marine navigation. More on-line, real-time processing of data gathered on-board small ... View full abstract»

    During the last 10 years, the use of hand-held calculators has become feasable for navigation problems. The prices of the calculators have dropped precipitously and miniturization has significantly increased the capabilities of the hand-held calculator. But more significantly, miniturization has resulted in full-scale personal computers which can be used for navigation. In 1976, Almanac for Comput... View full abstract»

    This paper presents comparative assessments of navigation systems in terms of their ability to satisfy current and projected civil aviation requirements. Emphasis is placed on U.S. operations. The navigation systems considered as candidates, either separately or in combination, for meeting post-1995 requirements are Loran-C, Omega/ VLF, GPS, VOR, DME, Doppler, and INS. Each navigation system is ch... View full abstract»

  • Some properties of electric current fields on a rectangle

    Publication Year: 1983, Page(s):1228 - 1229
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (179 KB)

    A rectangle has two mirror-symmetry axes and a twofold rotational symmetry center. The symmetry leads us to some properties of electric current fields: the resistance R1between two electrodes attached to the special part of a rectangle and the reciprocal resistance R2of R1makes the relation R1R2= 2, etc. View full abstract»

    A new counting and direction-sensing circuit which produces twice as many counting pulses as that of an earlier design is described. It offers two alternative advantages, i.e., it may be regarded as doubling the accuracy of displacement measurement or relaxing the stringent resolution requirement of a transducer, such as the Moiŕe transducer, by half.
