New Briefcase Computer

For Marine Industry From NAV-COM —Literature Available nication costs for modern commer- cial ships. The BUSISHIP system, which is designed around a rugge- dized IBM-PC/XT personal com- puter, uses specialized NAV-COM software for many shipboard man- agement functions, including on- board spares inventory, crew records and payroll, personnel rota- tion and assignment, and load/ stress/trim calculations.

GRiD computers have been field tested and are currently in use for a variety of applications ranging from

U.S. warships to offshore oil rigs and even on board space shuttle missions.

NAV-COM Incorporated is a leading U.S. marine electronics firm specializing in the integration of complex communications, naviga- tion and information systems. It is a wholly owned subsidiary of the

Magnavox Government and Indus- trial Electronics Company.

NAV-COM Incorporated, Deer

Park, N.Y., has been named an offi- cial value-added reseller for the line of portable computers manufac- tured by GRiD systems Corpora- tion. The GRiD computers have been integrated into NAV-COM's

BUSISHIP marine management in- formation system, using proprietary software developed by NAV-COM for marine data processing and sat- ellite communications. "The GRiD computers add a new dimension to our BUSISHIP pack- age," said NAV-COM president

Gerald A. Gutman. "It is a truly remarkable advance in the state-of- the-art in computer miniaturiza- tion, offering a unique combination of power, portability, ruggedness and versatility. These attributes make them ideally suited for the computing and data communica- tions requirements of the marine and offshore industries," he added.

The GRiDCase portable comput- er, which has a magnesium casing, weighs 12 pounds and fits into a standard-size briefcase. The 16-bit computer is IBM-PC compatible and can communicate with a wide assortment of personal computers

The GRiD portable computer is now avail- able with special marine management soft- ware from NAV-COM Incorporated. and mainframes. It can be config- ured for up to 512K RAM and 512K

ROM, and a 10 MB hard disk drive is available as an option. A built-in rechargeable battery pack permits the computer to be used without external power. An optional 1,200- bps internal modem links the

GRiDCase computer into telephone lines or satellite voice channels for data exchange.

Furuno USA Introduces New

Doppler Speed Log And ARPA Line —Free Literature Available

Furuno USA, Inc., South San

Francisco, Calif., has introduced a new ARPA series and a new com- pact doppler speed log, DS-70.

The DS-70 doppler speed log dis- plays vessel speed and distance run to accuracies of ± 1 percent. The system uses paired-beam transduc- ers to eliminate the effects of pitch and roll, and corrects signal velocity for changes in water temperature and salinity.

The new Furuno ARPA series, which are available either as stand- alone units that may be interfaced with existing Furuno or other ra- dars, or as completely integrated X- or S-band radar/ARPA installa- tions, consist of a 16-inch PPI radar display that shows raw radar echoes in amber and computed vector data in white, plus a control unit with a 9-inch daylight display for target data. The system provides for auto- matic acquisition of 20 targets and manual acquisition of an additional 10 targets within the range of 0.3 to 32 nm. Picture quality is achieved through the use of a logarithmic receiver and Furuno's custom hy- brid microwave IC circuitry. The trial maneuver function permits in- stant evaluation of potentially dan- gerous CPA and TCPA situations.

The operator can change any simu- lation characteristics without inter- rupting normal target information update. Audible and visual alarms are activated if there is collision risk, a target is lost, a target transits the guard ring, in a target saturation condition, or if there is a system fail- ure.

The DS-70 doppler speed log measures forward speeds through- out the range from 0 to 30 knots and speeds astern from 0 to 10 knots.

The DS-70 doppler speed log.

The distance run is displayed from 0 to 99,999.99 nm and may be reset by the operator to any value.

In addition to exceeding IMO,

IEC and other standards, the DS-70 provides standard output signals to

ARPAs, satnavs, onboard comput- ers, and other ship's equipment. Re- mote displays are available and, with an optional signal distributor, a wide range of multiple signal out- puts can be handled.

Chantiers De L'Atlantique

Wins LNG Tanker

Design Contract

Chantiers de l'Atlantique, a unit of Alsthom's Shipbuilding Division, has been selected to design a vessel for transporting liquefied natural gas (LNG) using the LNG/LIN liquid-nitrogen liquefaction tech- nique.

This design project included two orders, one placed to Chantiers de l'Atlantique and the other to Tech- nip. It is part of joint efforts imple- mented by Elf Aquitaine Norge and

Statoil for possible exploitation of gas fields off the coast of Norway.

Chantiers de l'Atlantique was chosen for its experience and repu- tation in the field of LNG carrier design and construction.
