Positioning

Only Raytheon gives you

A complete line sold and serviced around the world.

Satellite Navigator gives worldwide fixes accurate within 100 yards every 30 to 90 minutes.

The "complete navigator", Raytheon

JLE-3400 acquires and displays very accurate Lat/Long fixes derived from navy navigation satellites in polar orbit.

Between satellite fixes, computer- generated dead-reckoning fixes are shown. Dead-reckoning data is keyboard entered or automatically supplied by a gyro compass and dual-axis doppler log.'

Featuring a large 9-inch CRT, the JLE-3400 will also display such important data as: • Date and GMT • Time since last satellite fix. • Time and angle of next satellite fix. • Ship's speed and course. • Data from up to ten way-points including: course-to-steer for

Rhumb or Great Circle tracks, distance run, ETA's etc.

A printer for displayed data and a remote CRT display are available as options.

On the oceans of the world, we are most noted for our heavy-duty 3 and 10-cm radar systems.

More than 50,000 vessels have been fitted. While less visible, other

Raytheon products are even more numerous.

These include: • RAYCAS, the finest and most economical

Collision Avoidance

System yet devised. • VHF-FM and SSB

Radiotelephones. • Fathometer® Echosounders. • Doppler Speed Logs. • SATNAV and Loran-C. • Facsimile Receivers.

All sold and serviced in major ports everywhere.

DOPPLER LOGS

Doppler logs give accurate speeds and simultaneous bottom soundings.

Single or dual-axis.

There are three models of the famous

Raytheon

Doppler Log:

DSN-250 for continuous fore/ aft speeds;

DSN-350 which can be switched to show either fore/aft or port/starboard speeds: and DSN-450 which shows speeds in both axes simultaneously.

All three are proven performers with these unique features: • "Normal" mode readings up to 40 knots within 1/10 knot. "Mooring" mode readings accurate within 1/100 knot.

True speeds shown over bottoms as deep as 1000 feet. • Selectable "water-mass" mode for relative speeds through water. • Simultaneous bottom soundings to 1000 feet with adjustable minimum depth alarm. • Automatic water temperature and salinity compensation. 1 Self-testing. No calibration. 1 Large, easy-to-read LED display with mechanical "distance-run" counter. 1 Optional digital and analog "dial" remote displays. ' Single transducer.
