USCG Orders Differential GPS Equipment From Magnavox Magnavox recently received or- ders from the U.S. Coast Guard for differential GPS (DGPS) equipment which will be used to provide en- hanced navigational accuracy for ships and boats in U.S. coastal wa- ters and harbors. The Magnavox system uses the signals from marine radiobeacons to broadcast differential data which can be used by shipboard GPS re- ceivers to offset errors in the GPS satellites' navigational signals. The DGPS data is "piggy-backed" on the regular direction-finding/homing signals broadcast by the beacons. Magnavox has already supplied differential GPS beacon systems, which have been installed by the Coast Guard at St. Mary's River, Mich., and Wildwood, N.J. Similar systems will be installed at other East Coast and Gulf Coast beacon sites in early 1992. Magnavox has been a pioneer in the development of beacon-based differential GPS technology. Last year, the company installed the world's first public broadcast DGPS beacon system in the Baltic Sea, under contract from Swedish and Finnish navigation authorities. According to Steve Wilson of Magnavox, the use of differential techniques can improve navigational accuracy of GPS dramatically. The Coast Guard plans to make the DGPS broadcasts freely avail- able to the public. To take advan- tage of the system, a ship or boat will only need a beacon receiver, which can demodulate the DGPS data and provide it to a GPS re- ceiver capable of accepting and ap- plying differential corrections. Current Coast Guard plans call for expansion of experimental DGPS broadcasts to cover the entire East Coast from Maine to Cape Hatteras with five to six additional beacon sites during 1992. Magnavox has also supplied similar systems to Denmark, the Netherlands, Canada and the United Kingdom.

The agreement, aimed at further improving Technigaz LNG carrier technology, will enhance the two companies' services in the face of expected increases in demand for LNG carriers. The collaboration will extend to broad areas of joint R & D and design, improve building procedures and multiply the at- tributes of the companies' joint re- sources. The Technigaz tank system is composed of stainless steel mem- branes and insulation panels made of fiberglass-reinforced polyure- thane foam, which provides high reliability; a compact space-efficient hull; good bridge visibility and easy maintenance due to its low, flat up- per deck; and a complete double- hull structure, ensuring greater s&fcty Over the past 20 years, 12 LNG carriers with the Technigaz tank system have been built. The latest order was received by NKK in De- cember 1990 from Asia LNG Trans- port Sdn. Bhd. of Malaysia for a 635,661 cubic-foot LNG carrier. Maritime Reporter/Engineering News 23-* The European Workboat Show has expanded rapidly and successfully with last year's visitors voting the show a huge success. Well over 5000 trade visitors, from over 40 countries worldwide, attend the show to view the 200 plus exhibitor and on-water display of 100 craft. Many of the world's leading manufacturers of small commercial, military ano fishing craft are represented together with the vast range of equipment, components and services. LE PLUS GRANDE D'EUROPE... Lance en 1990, le European Workboat Show a rapidement pris de I'ampleur, et compte aujourd'hui plus de 200 exposants, 80 bateaux k flot et un nombre croissant de visiteurs (plus de 5000 visiteurs professionnels venus de 39 pays). Le site offrant cette annee une superficie superieure, on s'attend a ce que le salon s'Stende de nouveau pour 1992. EUROPAS GROSSTE... Die „ European Workboat Show", die 1990 zum ersten Mai stattfand, expandierte rasch und bietet nun 200 Ausstellern und 80 Booten zu Wasser Platz. Die Zahl der Besucher steigt stetig (uber 5000 Besucher aus 39 LSndern in aller Welt). Die VergrflBerung der Ausstellungsfl&che wird voraussichtlich auch 1992 zu einer weiteren Expansion fiihren.
