sized boats and to business persons who travel to remote parts of the world.

The service, which uses a newly introduced "Inmarsat-M" technology over the global Inmarsat satellite system, is being marketed by

COMSAT under the name Mobile


According to Chris Leber, vice president of COMSAT's digital ser- vices, the rate for COMSAT's Mo- bile Link voice service has been set at $5.50 per minute, which com- pares to a basic rate of $ 10 per minute for its existing "Inmarsat-A" satel- lite service.

Mr. Leber said that Mobile Link is a global, two-way digital commu- nications service that will initially provide a telephone capability through COMSAT's Southbury,

Conn., and Santa Paula, Calif., land earth stations by mid-1992, and will be expanded for facsimile and data communications later this year.

EDO Corporation, Electro-Acous- tic Division, Salt Lake City, Calif., offers the model MRQ-4015DM two axes speed log. The MRQ-4015DM doppler velocity log, which has been used by the U.S. and Korean Navies in their minesweepers, provides both fore/aft and port/starboard veloci- ties, in addition to distance traveled and depth. Speed range on both axes is 0-39.9 knots, with bottom tracking to 600-foot depth. The sys- tem can be forced to track the water column rather than the bottom at any time from a front panel control.

Construction is of a nonferrous ma- terial providing low-magnetic signature required on vessels in- volved in mine warfare operations.

A standard system consists of: main display and control unit, main electronics unit (MEU), transducer junction box, and transducer.

The system design allows cable lengths of up to 1,200 feet between transducer, J-box and MEU, and between MEU and main display and control unit.

EEV Inc.'s marine magnetrons, which are used worldwide in marine navigation radar, are designed for long and reliable operational life.

The use of EEVs patented ridged cathode throughout the range guar- antees the user long life and consis- tent performance. This is a direct contribution to improved radar reli- ability and reduced downtime. The ridged cathode gives life an order of magnitude greater than conven- tional types.

Metal-ceramic construction throughout permits high tempera- ture processing during manufacture, providing a stronger and more reli- able vacuum envelope. EEV 3rd generation magnetrons all use an efficient, lightweight magnetic cir- cuit for reduced susceptibility to demagnetization during handling and reduced shipping cost due to lower weight and lower stray mag- netic field.

The EEV range of marine magne- trons covers powers of 1.5 kw to 25 kw in X-band and 5 kw to 60 kw in S- band.

Electronic Marine Systems, Inc. (EMS), reports its GPS Chart Viewer can provide 10-foot accuracy with its differential receiver. The unit comes standard with a six-channel parallel processing receiver, with a 12-channel unit optional. Called the "navigation instrument of the 90s" by EMS, the GPS Chart Viewer also offers one of the most powerful displays available. The unit's thin line display makes the overall pack- age 2- 1/2-inches deep and weigh only 7 pounds. All units can be made portable for "Life Boat Applications" with the addition of the internal battery pack. The GPS Chart Viewer is manufactured to two different marine mil spec environmental specifications for water and salt ex- posure, as well as being designed to meet a 5 G peak shock specification.

The GPS Chart Viewer features automatic or manual dead-reckon- ing; a standard worldwide chart package; the ability to plan 30 voy- ages with 99 waypoints; shows all depths, buoys and markers on the inland waterways and Great Lakes; and has special user charts and maps.

Frotronics, Inc., a Houston-based marine marketing firm, has an- nounced their appointment as ex- clusive sales representatives for two leading marine electronic equipment manufacturers, Tokimec and Philips


Frotronics will market these new products through selected marine sales and service dealerships throughout the U.S. and Canada.

Tokimec, Inc., formerly known as

Tokyo Keiki, manufactures marine radar, gyrocompass, autopilot and speed log equipment.

The Tokimec RASCAR series of

ARPA radars employ 'touch screen" technology, using man-machine in- terface menus to totally eliminate the use of knobs or push buttons in the operation of the radar.

Philips Radio Communications,

Inc., of Denmark, supply low-cost satellite communications via PC and telex. The Philips SAFECOM CM and CP terminals are based on the new Inmarsat-C satellite system.

Special software compresses data, saving transmission time and cost.

For customer support, Frotronics stocks equipment and spare parts at its Houston warehouse.

Furuno, recognized as a leader in marine electronics, has announced a new GPS navigator built to deliver top performance and reliability un- der the most punishing conditions— the Furuno GP-70.

The new Furuno GP-70 offers the latest GPS technology in a tough, compact and completely water-tight package. It features rugged cast metal enclosures—not plastic—and watertight membrane keypads, all designed to protect the state-of-the- art receiver from moisture and salt spray.

The GP-70's large, backlit LCD display provides a wealth of impor- tant navigation data at a glance. Its dual-channel, eight satellite track- ing capability provides the depend- ability, speed and accuracy.

A universal power supply allows the GP-70 to operate on as little as 10 volts—and on as much as 40. In addition, two fully programmable

NMEA 0183 outputs allow the GP- 70 to be integrated with plotters, sounders, autopilots and other ma- rine electronics systems, to create the All-Furuno Bridge.

Compact in size, the GP-70 uti- lizes a slim-profile, 500-gram an- tenna, which allows for easy instal- lation on a wide variety of offshore vessels.

Late last year, Garmin Commu- nication & Navigation, Lenexa,

Kan., introduced the GPS 50 Per- sonal Navigator, a feature-packed model that gives users the conve- nience of a hand-held unit with the power, sophistication and reliabil- ity of much larger models. Using

Garmin's MultiTrac system, the waterproof, pocket-sized unit can track up to eight satellites at a time— from horizon to horizon—for excep- tional sensitivity and accuracy. GPS 50 owners can also take advantage of 250 waypoints and nine revers- ible routes, with a fast first-fix, one- second updates, and AutoLocate, which eliminates the need for ini- tialization. When not being used as a portable, the unit can be surface mounted to the panel or placed in a rotating swivel mount, offering ad- justable viewing angles. Nighttime and harsh-weather operators will appreciate the easy-to-read alpha- numeric keypad and display, which are both backlighted for low-visibil- ity use.
