ALDEN The first of a new series of Marinefax weather chart recorders was introduced by Alden Electronics, Inc., Westboro, Mass. Designated the Marinefax TR 1, the new recorder features a high-quality thermal printer for crisp, white dry paper recordings and a microprocessor- based programmable memory that lets the operator select not only the time and frequency of desired charts but various transmitters as well. The Marinefax TR 1 will automatically turn itself on, select the desired frequency, select the desired transmitter, receive the chart and turn itself off. This cycle can be programmed to occur for up to 250 on/ off sequences. A scrolling LCD display provides all necessary prompts.

The Marinefax TR 1 also incorporates two unique memory functions.

One function is permanent and is used to store all worldwide radiofax frequencies for easy two-step recall, the other function is used as a local memory to store up to ten frequencies for single-button recall. Any HF frequency in the world may also be manually entered into the receiver.

The Marinefax TR 1 also features a highly stable radio that can be tuned as precisely as 0.1 kHz for optimized reception without fine tuning. This feature makes it easier to program the radio to receive from transmitters using odd frequencies of half a cycle above whole kHz stops.

The Marinefax TR 1 shares all the features, such as compact size and light weight, as previous Marinefax recorders. It operates off 110 and 220 VAC as well as 12, 24, 32 VDC.

Circle 10 on Reader Service Card ATKINSON DYNAMICS Atkinson Dynamics, a division of Guy F. Atkinson Company, offers several industrial intercoms for the marine industry, which deliver clear dependable voice communication under the most severe operating conditions.

Solid-state components enable the intercoms to withstand vibration or rough usage, while cast aluminum cases prevent internal damage to operating components from dirt, corrosive fumes or moisture, as well as allow stations to be installed in unprotected outdoor locations.

Typical installations of Atkinson intercoms include onboard ship— bridge to deck or engine room, control center to diving bell—on offshore oil platforms—and throughout repair yards, drydocks, piers and storage areas.

Atkinson Dynamics intercoms perform well regardless of high ambient noise, weather or temperature extremes. Each unit is self-contained station that receives, amplifies and transmits, making it possible for the intercom systems to include almost any desired number of stations and to extend over very long distances. Installation is simple, since each unit plugs into a nearby AC or DC power source and then is connected by an ordinary low voltage two-wire cable.

The Robertson Multipurpose Pilot is a single station from which the ship's master can control a vessel under the following operating conditions: vessel maneuvering— three-axis joystick controls vessel position, heading and speed; automatic tracking—input from a navigation system will allow the vessel to track along a predetermined track, with joystick override; remote steering— steer one vessel from another or have the surface vessel follow a sub automatically or manually; and transit—autopilot control.

The On-Line-Monitor is a solid state monitor which provides constant monitoring of insulation values of generators, compressor, pumps, motors and supply cables, in either the running or stand-by mode. As insulation resistance deteriorates due to moisture, cable damage, carbon build-up, etc., an alarm is flashed and sounded.

Secure radio remote control of a barge or rig from a tug or a remote point is available with the U.C. Control Sentinel. The Sentinel is a computer control system which allows the master station to monitor the status and remotely control barge steering, navigation lights, anchor windlass, pumps, motors, compressors, thrusters, generators, ballast control and more.

Circle 45 on Reader Service Card COMSAT MARITIME COMSAT Corporation of Washington, D.C., is celebrating this year the 10th anniversary of the world's first commercial maritime communications satellite system. The first commercial telephone transmission through the company's MARISAT System took place on July 9, 1976.

According to COMSAT Maritime Services officials, the first call passed routinely through the system.

It was a business call between the seismic ship Deep Sea Explorer, searching for oil in the Indian Ocean off the coast of Madagascar, and the home office of Phillips Petroleum Company in Bartlesville, Okla.

The MARISAT System was designed and developed by COMSAT General, a subsidiary of COMSAT Corporation. COMSAT General successfully launched three MARISAT satellites in 1976, one over each ocean region, which allowed cost-effective sharing of satellite telecommunications services for both military and commercial maritime interests.

In the 10 years since the initiation of maritime satellite communications, the system has grown dramatically along with the range of services available. In 1982 the International Maritime Satellite Organization (INMARSAT) was formed, and now 46 countries are members.

More than 4,000 vessels and offshore oil platforms have been equipped with ship earth stations, allowing more than 300,000 people per day to have access to satellite communications on the high seas.

COMSAT Corporation was selected to represent the U.S. in INMARSAT, and currently utilizes and therefore owns 29 percent of the system. COMSAT Maritime Services oversees the company's role in INMARSAT, and has been instrumental in developing and marketing new services for the seafaring community.

It was responsible for the first live television satellite broadcast to a ship at sea when it transmitted the Super Bowl game to the Queen Elizabeth 2 off the coast of Peru early this year.

Circle 20 on Reader Service Card JAPAN RADIO Japan Radio Company, Ltd., is marketing two new products—the JLR-4000 GPS Navigator and the GSC-80 On-Board Data Automatic Recording System (ODARS).

The GPS NAVSTAR system with timing and ranging is completely new and will eventually use 18 satellites to pinpoint a ship's position and speed anywhere in the world with great accuracy. The system currently uses seven satellites now in orbit, allowing measurement of positions for about three to five hours a day. Twenty-four-hour service will be available in 1987.

The JLR-4000 navigator is said to be one of the most compact and lightweight units in the world, with a unique time-sharing feature. As the GPS navigator receives signals from four satellites to measure a position, four or five receiving channels would normally be required.

However, the time-sharing system developed by JRC permits the receiver to receive the signals from all four satellites on a single channel for instant position fixing. The GPS receiver determines not only latitude, longitude, speed, and bearing— the basic functions—but it can also indicate such navigational data in memory as destination, bearing and distance to destination, required time to it, off-course alarm, etc.

The GSC-80 ODARS has been developed to meet demands for automated data communications through the INMARSAT from ship to shore. It is an automatic data reporting system to collect various types of onboard information and to automatically transmit the newest data to the shipowner's office ashore via the INMARSAT telex link.

The system consists of a multidata interface and a telex channel interface that are connected to an existing or new INMARSAT ship earth station. The GSC-80 can transmit data to shore using three modes—fully automatic, semiautomatic, and manual. The onboard data received at the shore office is analyzed and processed to send a relevant sailing plan back to the ship.

Circle 21 on Reader Service Card KRUPP ATLAS New-generation navaids available from Krupp Atlas Elektronik (KAE), with U.S. operations in Railway, N.J , include the Atlas 7600- 8600 16-inch rasterscan radars, which offer continuous televisiontype viewing under all conditions.

Comprising RM, TM and two ARPA models, all are FCC type- approved and are designed to meet IMO, USCG and other leading specifications.

Over 500 of these radars have already been sold worldwide. U.S.

customers include the New Jerseybased Sealand Company who are to install a series of 7600 X and S-band RM and TM units on new container vessels destined for the Alaskan trade.

Principal features of these advanced radars include a centered TM display mode for maintenance of own ship position fixed on PPI while indicating targets with their true trails; adjustable lengths of target trails may also be generated for rapid orientation to given traffic situations.

A newly developed 12-inch variant of the 7600-8600 series, the Atlas 5600, is also available. Suitable for small ships of any size or class, it is designed to operate over nine ranges extending from 0.3 to 72nm.

Available with either X or S-band transceiver/slotted array antennae, the 5600 can be interswitched for cross-connection as well as masterslave operation.

The 7600-8600 radars also have been adapted for vessel traffic control applications, allowing for transmission of radar data from remote sites to central control. For these uses, KAE has adopted narrow band compression techniques in which signals from the radar transceiver, such as antenna angle pulses, north reference pulse, radar trigger and video, are all reduced to a common signal and then shaped to conform with any standard industrial TV transmission format using coaxial cable, fiber optic systems, twin-wire connections or microwave links of differing frequencies.

The radars also form an integral part of KAE's advanced NACOS 20 modular navigation bridge control system designed for single manning and which is already beginning to attract considerable U.S. interest. A basic configuration comprises an 8600 ARPA and either a 7600 TM or ARPA, an Atlas Dolog 23 doppler log, echo sounder and an adaptive radar-controlled autopilot, or ARCAP, for which the 8600 also provides input and monitoring facilities.

Also included is a full-color navigation information display (NID) console together with interfaces for other sensors and bridge equipment.

Circle 22 on Reader Service Card MAGNAVOX Magnavox is offering the new MX 4400 GPS Positioning and Navigation System, designed as a full-featured two-channel C/A code receiver.

The unit has been designed by Magnavox for use with the current interim GPS constellation and with increasing utility as more satellites are employed.

The two-channel receiver provides continuous GPS navigation, without interruption, whenever sufficient satellites are available. The MX 4400 can navigate with as few as two visible satellites when an external atomic frequency standard is interfaced and altitude is known (sea level) or determined from the receiver's altimeter. This capability extends the number of hours per day that the MX 4400 receiver can be used. To provide navigation during GPS coverage gaps, the MX 4400 will automatically dead reckon using inputs from external speed and heading sensors.

Magnavox plans to introduce software in 1987 to permit the MX 4400 to accept GPS differential corrections in the standard RTCM SC- 104 format. The differential inputs will result in enhanced dynamic accuracy in real time.

In order to provide continuous, optimum navigation and positioning information, the MX 4400 employs an 8-state Kalman filter which evaluates and weighs satellite data.

A 16-bit numerical co-processor provides position, speed and heading updates every 1.2 seconds. The system has the capability of providing GPS data to integrated survey systems such as the Magnavox Series 5000 Geophysical Survey System.

In addition, the Magnavox Advanced Products & Systems Company recently announced the creation of a program for worldwide rentals of its navigation, communication and survey products. NAV-COM Inc., a Magnavox subsidiary, will be the rental agent for the program.

Circle 49 on Reader Service Card TELEDYNE Teledyne Hastings-Raydist, Hampton, Va., manufacturer of medium- range, precision radiopositioning systems, has introduced the TRAK IV system.

Raydist TRAK IV is an improved version of the well-known Raydist DRS radiopositioning system utilizing "atomic clock" frequency standards and state-of-the-art technology to achieve practically unlimited user capability in the rho/rho mode on a single frequency allocation anywhere in the MF/HF band.

The new unit is particularly well suited to radiopositioning applications in which a relatively large number of simultaneous users must operate at ranges up to several hundred kilometers with a geodetic accuracy of a few meters. The rho/ rho (circular) geometry makes the TRAK IV ideal for coastal applications, regardless of whether the coastline is concave, straight, or even convex. The comparatively broad lane widths (typically 100 meters or more) make lane recovery much easier than with other phase comparison systems.

The ability to track up to four LOPs continuously and simultaneously greatly increases system reliability.

When used with the Raydist Director (microcomputer), interchecking is permitted between the redundant position data to achieve a statistically desired "bestfit" position solution and a "figure of merit" indication of probable accuracy.

The Raydist Director also permits op-area initialization so that the correct fractional values of the several LOPs can be established and/or verified in the actual area of operations.

Circle 42 on Reader Service Card TEXAS INSTRUMENTS Texas Instruments has introduced a new relative-positioning software package, Geomark, designed to process data collected by the TI-4000 Global Positioning System (GPS) Navigators.

The Geomark software for GPS provides highly accurate postprocessing positioning information from data collected by two TI-4100 GPS Navigators simultaneously tracking the same four GPS satellites.

The TI-4100 is a satellite-based navigation system that provides precise absolute positioning or relative point-positioning surveys, including aerial surveys, offshore platform positioning, marine navigation and oceanographic and geophysical surveys.

The Geomark software provides typical solutions in less than one hour of off-line processing using as little as 30 minutes of collected data, including data cassette translation.

Geomark offers totally automatic operation. Users may enter custom specifications by overriding the automatic defaults. Users can also specify the reference location or derive the location using the TI- 4100. Geomark processes both Precise Code (P-Code) or Coarse/Acquisition (C/A Code). The software uses broadcast ephemeris, but can also support post-mission precise ephemeris.

Geomark records all necessary data on a one-page report that provides the user with the monumentto- monument baseline vector. The system can provide the answer in standard latitude, longitude, altitude; state plane; UTM; or local datum.

The complete TI-4100/Geomark package is available now and includes Geomark and MS-DOS™ software. The package also includes the TI Portable Professional Computer with 256K bytes RAM, a multifunction board with an additional 256K RAM, a single floppy diskette drive, a 10-megabyte Winchester hard disk drive, an 8087 coprocessor, three-plane graphics board, a built-in high-resolution 9-inch color monitor, two Memtec cassette readers, two RS-232 cables, and the TI 855 microprinter.
