UPDATE

Texas Instruments Introduces

New Satplan® Software For

Global Positioning System

Texas Instruments has an- nounced a new addition to its TI 4100 NAVSTAR navigator product line, an enhancement that makes the Global Positioning System (GPS) constellation more produc- tive as a navigation/positioning tool.

Called SATPLAN, the new soft- ware product provides specific sat- ellite visibility times and position dilution of precision (PDOP) infor- mation, according to John Apple- gate, marketing manager for TI's

Global Positioning System. PDOP helps the user select the best time at which the satellites are in a geome- try that will produce a more accu- rate position.

SATPLAN selects the four best satellites available to the user and provides information on precise

GPS satellite rise and set times, sat- ellite azimuth and elevation, satel- lite visibility profile, and the recom- mended navigation mode. "The benefit to the user," Mr.

Applegate stated, "is that SAT-

PLAN displays and prints the infor- mation in tabular and graphic form so that a detailed schedule of satel- lite availability can be quickly pre- pared, including an analysis of the most efficient times for GPS use in each location and on each date de- sired."

Using the TI Color Professional or Portable Professional Computer, with 256K RAM and 8087 numeri- cal co-processor, the easy-to-use

SATPLAN complements the TI 4100 GPS receiver. SATPLAN al- manac data can be taken directly from the TI 4100 receiver's display or can be updated from government or user sources. Almanac nomencla- ture is the same as that used by the

TI 4100.

SEGMENT

Marshall L. Field

M.D. Maddox, president of Colt

Industries' Fairbanks Morse Engine

Division in Beloit, Wise., has an- nounced the appointment of Mar- shall L. Field Jr. as vice presi- dent, manufacturing. He will be re- sponsible for all facets of the manu- facturing functions including mate- rials, manufacturing engineering, and all production departments.

Mr. Field comes to Fairbanks

Morse from FMC Corporation, where he was employed for the past nine years. During that time, he held positions of business planner, materials manager, and manufac- turing manager. His most recent as- signment at FMC was as a member of a new venture group in Houston.

Prior to joining FMC he spent four years with Westinghouse Electric

Company's Systems Development

Division.

He has a BS degree in electrical engineering from Georgia Institute of Technology, an MS in electrical engineering from Johns Hopkins, and an MBA from Harvard Busi- ness School.

Massport Building New $4-Million Passenger

Cruise Ship Terminal

Massport's Board recently awarded a $4-million contract to

Trust Construction Corporation of

Chelmsford, Mass., for construction of a new cruise ship terminal. The facility, to be called Harbor Gate- way Terminal, will be located at the

Boston Army Base in South Bos- ton.

Massport executive director Da- vid W. Davis called the new termi- nal an important piece of the overall development plan for the Boston waterfront. He pointed out that

Massport is making efforts to at- tract additional cruise lines to Bos- ton, and that negotiations are con- tinuing with cruise operators who will use the facility. Last year 13 vacation cruises departed from the

Port of Boston, compared with 10 in 1983. Approximately 20,000 passen- gers take Boston-based cruises each year.

Designed by the engineering and architectural firm of Post, Buckley,

Schuh, and Jernigan, Harbor Gate- way Terminal will accommodate a 1,200-passenger cruise ship and a smaller 600-passenger vessel. Con- struction is expected to be complete in 10 months, though operations at the terminal sL will begin June 1 this year.

Marinette Marine Awarded $7-Million Navy Contract

For Two Additional TWRs

Marinette Marine Corporation of

Marinette, Wise., has been awarded a contract by the Naval Sea Systems

Command for the construction of two Torpedo Weapons Retriever (TWR) boats. The Wisconsin ship- yard had previously been awarded in 1983 a Navy contract for eight vessels of this class.

The TWR class vessel is a totally new design developed by Marinette

Marine to replace the Navy's aging existing TWR vessels. These craft are utilized by the Navy for recover- ing spent torpedoes, missiles, small drones, and mobile targets fired during weapons systems tests of all submarines and other combatant ships. The newly designed TWR is capable of staying on station for a week in support of these tests, thus avoiding the long delay times for ships caused in the past by smaller boats that had to return to base at night and then return to the test site the next day.

The TWR vessel is 120 feet in length with a beam of 25 feet, depth of 12 feet, an approximate displace- ment of 213 tons. The craft is entire- ly steel construction with a total propulsion power of 2,000 bhp driv- ing twin fixed-pitch propellers. De- sign speed is 16 knots and range is 1,700 nautical miles.

Delivery of the first two TWRs ordered in 1983 is scheduled for spring this year; the two vessels in the new award are expected to be delivered in June 1986.
