Mctgnavox Introduces Civil Global

Positioning System —Literature Available

Magnavox Advanced Products and Systems Company of Torrence,

Calif., recently announced the avail- ability of a civil Global Positioning

System (GPS) navigator (shown be- low). Designated the T-Set, it is a

C/A code receiver with system accu- racy equal or superior to the Magna- vox Z-Set developed under the

Phase I Military GPS Program, which demonstrated 30-35 meter dynamic accuracy during field tests.

Actual accuracy obtainable depends upon the quality of orbit parameters and clock corrections transmitted to the satellites.

The T-Set consists of the follow- ing components: electronics unit, consisting of VT-103 terminal,

PDP-11/23 computer, Magnavox

GPS receiver card, and Magnavox positioning and navigation software; antenna assembly; and coaxial cable (100 meters).

Five independent receiver chan- nels are provided in the T-Set to permit continuous tracking of the four currently best satellite signals while the fifth channel gathers ephemeris data from all other po- tentially useful satellites. This al- three satellite signals. With a rubid- ium or cesium frequency standard, navigation can continue when only two satellites are available.

Data displayed on the T-Set in- clude time, position, speed, course, satellite number, azimuth, eleva- tion, signal-to-noise, range residu- als, solution variance, and dilution of precision. Satellite alerts and sta- tus data also are displayed. These data plus the almanac, ephemeris, and all pseudorange and Doppler measurements are available via the

RE-232 data port. A lower rate of navigation results may be recorded by the internal cartridge tape drive.

The T-Set is intended for sale or lease to customers who are inter- ested in obtaining experience with

GPS. The system is designed for operation in a controlled enviro- nment. Environmental, physical, and electrical characteristics of the

T-Set are defined by the VT-103

Terminal specification.

The GPS satellites currently in operation are experimental in na- ture, and the U.S. Government has the right to modify or terminate the operation of these satellites at any time. The sale or lease of the T-Set to customers outside the United

States is subject to U.S. Govern- ment regulations.

For more information and com- plete literature on the T-Set,

Circle 10 on Reader Service Card lows the T-Set both to switch satel- lites without delay and to respond quickly to vehicle dynamics, thus insuring optimum accuracy at all times.

Differential GPS navigation is a planned option. One T-Set at a fixed site will monitor the available satellite signals and compute range and Doppler corrections. Navigat- ing T-Sets will receive and apply the corrections before computing each navigation solution. Differential ac- curacy is expected to be five meters or better, taking full advantage of the five-channel receiver design.

Extended naviation coverage is available when altitude is known, e.g., for marine use, by means of the automatic geoidal height correction that permits navigation with only

IMODCO Awarded Contract

By Esso Suez For Mooring

Terminal Offshore Egypt

IMODCO of Los Angeles, a unit of AMCA International Corporation and pioneer offshore marine termi- nal company, has been awarded a contract by Esso Suez, Inc. for a catenary anchor leg mooring (CALM) terminal. This unit for

Esso is designed to securely moor tankers of up to 85,000 dwt, pri- marily for the loading of crude oil in the Gulf of Suez, offshore the East

Coast of Egypt. The value of the contract was not disclosed.

This terminal, nearly 28 feet in diameter and 10 feet deep, will be installed in 95 feet of water. In addi- tion to a 16-inch diameter line to load crude oil, the cargo system includes a 12-inch diameter line to simultaneously unload tanker de-

IMODCO installations are a com- mon sight in Egyptian waters. An inventory buoy was provided to

Arabian Petroleum Pipeline Com- pany (SUMED) in 1982 for Sidi-

Kerir in the Mediterranean for re- placement use when two previous buoys sold to SUMED in 1976 un- derwent overhaul. Two other

IMODCO buoys remain in opera- tion for the same company in the

Pitcock Appointed Vice

President-General Manager

Of Anixter-Cincinnati

Ron Pitcock has been named vice president and general manager of Anixter-Cincinnati, a joint ven- ture between Anixter Bros., Inc., of

Skokie, 111., and Cincinnati Bell, it was announced by John Egan, ex- ecutive vice president of Anixter

Bros. Mr. Pitcock will be responsi- ble for directing Anixter-Cincinna- ti's overall operations.

A veteran of the communications industry, Mr. Pitcock has been with Anixter since 1980. He has held a variety of sales and management positions with the company, most recently as CATV district manager-

Houston.

Anixter-Cincinnati supplies a complete line of telecommunica- tions systems and equipment,

CATV equipment, and electrical and electronic wire and cable to a three-state area that includes parts of Ohio, Kentucky, and Indiana.
