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.

NKK, Hitachi Zosen

Cooperate To Build

Technigaz LNG Carriers

NKK Corp. and Hitachi Zosen

Corp. recently entered into an agree- ment to build Technigaz-based LNG carriers under license from Societe

Nouvelle Technigaz of France.

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.
