NAVIGATION & COMMUNICATIONS
1992 REVIEW The Global Maritime Distress and Safety System (GMDSS), one of the most significant advances in marine communications history, will be phased in from now until February 1999.
GMDSS will offer improved and reliable distress alerting and better facilities for distress location; increased automation; improved communications for rescue; and reduced reliance on specialist operators.
GMDSS has been made possible by technological breakthroughs and advancements in satellite communications and navigation, electronics, computer-controlled systems and software.
GMDSS requires that a deepsea ship be outfitted with a bevy of electronics, among which are: two Inmarsat A or Inmarsat C satcoms or a combination, a VHF radio telephone, NAVTEX receiver, 406 MHz EPIRB, MF radio telephone, MF watch receiver, automatic direction finder, and waterproof VHF walkietalkies.
This review examines some of the GMDSS-required equipment offered by major marine electronics manufacturers, as well as other new products and services for navigation and communications.

ROBERTSON MARINE SYSTEMS Circle 25 on Reader Service Card The paper chart has been a fun- damental tool for the last century, but now the limitations of this classic approach can be overcome by using new technology—GPS and Electronic Chart Display and information Systems (ECDIS).
A leader in the development and field testing of ECDIS systems has been Robertson. The Robertson Disc Navigation ECDIS is designed to satisfy the IMO provisional performance standards of ECDIS. Disc Navigation is designed for electronic sea charts based upon an authorized hydrographic data base which can be updated either manually or automatically via Inmarsat. The system has the capability of reading chart data in Norwegian Hydrographic Society-format and prepared for the international DX90 format.
All symbols and colors are used in accordance with IHO Colors and Symbols Group. The system satisfies Det norske Veritas automatic steering regulations.
The Disc Navigation operator console consists of a master display, a second interactive graphic display, a dedicated keyboard and roller ball.
SIMRAD Circle 100 on Reader Service Card Simrad, Inc., Lynnwood, Wash., is offering Anritsu's RA-722UA and RA-723UA radar. These Anritsu radars represent the latest in radar technology. A new high-speed microprocessor provides even further improvement on Anritsu's well-established reputation for superior target detection and definition.
Some of the standard features of the Anritsu radar systems include 15-inch high-resolution monochrome display; eight-level quantization; and such target detection techniques as High Sensitivity (AVS), Echo Stretch Function, Automatic or Manual Sea Clutter (STC) Control.
The RA-722UA, which has 10 kw of power, and the RA-723UA, with 25 kw of power, feature a large 15- inch monochrome picture, with automatic or manual target plotting, off-centering of the radar picture, a guard zone with alarm, and picture expansion of a selected area.
SINGAPORE TELECOM Circle 26 on Reader Service Card Singapore Telecom, which provides Inmarsat-A services to the Pacific Ocean Region via the Sentosa Coast Earth Station, recently passed along additional savings to customers in the form of rate reductions for telephone service to Batam and for maritime satellite communications services.
The company, which reviews its rates and services regularly in an effort to offer the lowest possible costs to customers, reports that ships in the Pacific Ocean Region are enjoying lower traffic charges for shipto- shore telephone and telex calls.
With this reduction in traffic charges, the company estimates t h a t more than $1.2 million in savings will be passed on to the maritime community per year. The lower traffic charges will mean lower communications costs for ships using Inmarsat-A services.
The Sentosa station also offers value-added services like Telepac and Telebox for ships.
SPERRY MARINE Circle 28 on Reader Service Card Sperry Marine, Charlottesville, Va., recently introduced its new "P" version RASCARs. The "P" version RASCAR radars ("P" for plotter), which contain no ARPA functions, have been designed to make a significant reduction in cost in dual radar systems where only one ARPA is required and in single radar systems on vessels below 10,000 gross tons where no ARPA is required.
This latest addition to the Sperry Marine RASCAR family includes a 20-target manual plotting capability made elegantly simple for the operator through RASCAR's touchscreen control. Up to 20 targets can be assigned their own track letter and, based on manual position updates, target course, speed, CPA and TCPA are automatically calculated and displayed.
The high resolution displays of the "P" version RASCARs retain the picture quality and touchscreen control of other Sperry Marine RASCARs. The "P" version RASCAR displays are completely compatible with existing RASCAR transceivers and antennas and are interswitchable with the standard RASCAR display, as well as with other "P" version displays.
STANDARD COMMUNICATIONS Circle 6 on Reader Service Card Miniaturization has come to Standard Communications line of Horizon marine radios with the introduction of the new HX230S "shirt pocket-sized" subcompact five-watt VHF handheld radio.
The HX230S, like all Horizon s c a n n i n g radios, may be programmed by the user to scan exactly the number or combination of channels desired. Or the user may push the P-scan button to give priority to the channel 16 button to immediately bring it up. A large LCD display makes the selected channels easily visible.
Simple controls give the HX230S easy access to all U.S., Canadian and international channels, as well as 10 weather channels. A push button gives the user instant access to 10 weather channels. The radio also includes a special battery-saving circuit which saves vital battery life.
An optional voice scrambler is available for the Horizon HX230S for users who want communications security.
TRIMBLE NAVIGATION Circle 23 on Reader Service Card Trimble Navigation recently unveiled three new products—two graphic display GPS receivers, the NavGraphicXL and NavTracXL, and the Acutis 6 GPS antenna receiver.
The displays of both the NavGraphicXL and the NavTracXL systems incorporate FSTN (film super twist pneumatic) technology, the latest development in liquid crystal computer displays (LCD), making them very easy to read.
The NavTracXL Graphic GPS receiver is designed primarily for offshore recreational cruising boats larger t h an 20 feet, fishing and workboats and smaller commercial ships.
The integrated NavGraphicXL GPS navigation and electronic charting system is targeted at both smaller recreational vessels and larger commercial fishing boats, research vessels and merchant ships. Like its predecessor, the NavGraphicII, the NavGraphicXL system automatically displays the vessel's exact position on a screen showing a detailed chart, which reads from a compact disk containing dozens of digitized NOAA charts.
The compact Acutis 6 is an integrated six-channel GPS antenna/ receiver that mounts above board like an antenna.
WATERCOM Circle 7 on Reader Service Card Since service to the inland mar i n e i n d u s t r y began in 1986, WATERCOM has installed hundreds of telephone fax and data units on vessels navigating America's inland waterways.
With WATERCOM, callers dial numbers directly; there is no need for an operator to complete the call.
Waiting to make connections is virtually eliminated, and the system offers improved clarity and privacy.
It also offers modem and facsimile data transfer capabilities.
Business calls are billed on an itemized usage statement. Personal calls made by crew members must be made collect, billed to a third party or charged to a credit card.
The company never sees a bill for them. Incoming calls are the dialing party's responsibility.
WATERCOM is reportedly the only direct dial, delay free, continuous communications system on the water. The system serves more t h a n 4,000 miles of America's waterways.
WATERCOM is a registered trademark of Waterway Communications System, Inc., Jeffersonville, Ind.
DEL NORTE Circle 115 on Reader Service Card Del Norte Technology, Inc., formed in 1969, has designed, manufactured, and supplied Precision Marine Positioning equipment to surveying, dredging and military authorities for over two decades.
During this time Del Norte has remained at the forefront of technology with the continuous development of its range of microwave meas u r i n g equipment known as Trisponders.
The 586 Digital Distance Measuring Unit (DDMU) is fully compatible with existing Trisponder systems, and may operate with any remote transmitter/receiver units already deployed.
The Del Norte 1008/1012 GPS receiver is a 586 DDMU fitted with a GPS module and is capable of carrying out all functions of a microwave measuring unit at the same time as operating as a GPS receiver.
For differential GPS operations, the Del Norte 1008/1012 resident software enables operation as either a shore-based reference unit or a shipborne mobile unit.
