itolt Names Final Two 1,000-Ton Parcel Tankers :or Inter Europe Service

The last two of four new 5,000-

Iwt parcel tankers for use by the •Stolt-Nielsen Inter Europe Service .SNIES) were recently named in formal ceremonies at Fukuoka Ship- ouilding Co., Ltd. in Fukuoka, Ja- pan. The two ships, M/T Stolt

Kestrel and M/T Stolt Puffin, will be marketed by Stolt-Nielsen UK Lim- ited, a subsidiary of Stolt Tankers and Terminals (Holdings) S.A.

These ships, together with two delivered in March of last year, will further strengthen Stolt-Nielsen's position in the European regional distribution trade. They feature one of the most advanced tanker designs, including a double hull with all cargo tanks of the highest grade solid stainless steel, each served by an individual deepwell pump. The ships meet all requirements to carry the full range of bulk liquid cargoes with maximum safety and environ- mental care. The addition of these ships provides SNIES with one of the most modern coastal parcel tanker fleets in Europe.

Stolt Tankers and Terminals pro- vides distribution services world- wide for bulk liquids by employing a fleet of transoceanic and coastal par- cel tankers; intermodal tank con- tainers; storage terminals in the

U.S., Northwest Europe and Brazil; as well as barges, rail cars and tank trucks.

Magellan Helps GPS Accu- racy With New Products

Magellan Systems Corp. has ex- panded the utility of GPS naviga- tion, improving GPS accuracy a re- ported 10-fold with the company's new NAV 5000D and NAV 5200D receivers. "The NAV 5000D and NAV 5200D are no longer restricted to

Magellan increases GPS accuracy with the differ- ential-ready NAV 5000D and NAV 5200D, and the

Magellan Differential Beacon Receiver. the 100-meter accuracy limit im- posed by the U.S. government's policy of Selective Availability," said

Marc Rubenstein, Magellan's sales and marketing manager. "In fact, they will give the user an in- credible 10-meter accuracy."

Magellan receivers use differen- tially corrected GPS (DGPS) infor- mation broadcast by the USCG's radiobeacon transmitters. The

USCG calculates the amount of er- ror in the GPS signal by comparing raw GPS position data with a known position point. This error correction factor is picked up by Magellan's differential broadcast receiver (DBR) and relayed to the differential-ca- pable NAV 5000D and NAV 5200D.

In overcoming the signal position error caused by Selective Availabil- ity, Magellan processes the correc- tion data using its proprietary

TRUFIX differential technology.

Magellan's TRUFIX differential technology, a spin-off of the company's work in developing GPS receivers for the U.S. military, in- corporates complex algorithms which allows the receivers to differ- entially calculate a precise position while maintaining dynamic perfor- mance characteristics which result in a one-second update rate and improved velocity accuracy. The dataport simultaneously receives the DGPS correction signal from the

DBR and transmits NMEA 0180/ 0183 output to marine electronics devices.

Magellan's differential-ready re- ceivers, the portable NAV 5000D and the panel-mounted NAV 5200D, also include new features such as a graphical cross-track deviation in- dicator and a man-overboard key.
