FOREWORD  
Foreword  
Features  
Thank you for purchasing the FURUNO  
DS-80 Doppler Speed Log. We are  
confident you will discover why FURUNO  
has become synonymous with quality and  
reliability.  
The FURUNO DS-80 displays ship’s speed  
relative to water, using the Doppler  
principle; ship’s speed is measured by  
detecting the Doppler shift frequency from  
the signal returned from the watermass.  
Dedicated in the design and manufacture of  
marine electronics equipment for half a  
century, FURUNO Electric Company has  
gained an unrivaled reputation as a world  
leader in the industry. This is the result of  
our technical excellence as well as our  
worldwide distribution and service network.  
The output is interfaced with ARPA, AIS,  
and other shipborne equipment in IEC  
61162-1 format.  
The main features of the DS-80 are  
Simple operation. In most cases all that  
is required to display ship’s speed is to  
turn on the equipment.  
Please carefully read and follow the safety  
information and operating and maintenance  
instructions set forth in this manual before  
attempting to operate the equipment and  
conduct any maintenance. Your Doppler  
speed log will perform to the utmost of its  
ability only if it is operated and maintained  
in accordance with the correct procedures.  
Pair-beam system effectively reduces  
error caused by pitching. The transducer  
assembly symmetrically emits two sonic  
beams, one fore and the other aft. By  
averaging the Doppler shift in both  
directions accurate speed data is  
available under rough sea conditions.  
Speed and distance information on the

PRINCIPLE OF OPERATION  
The Doppler speed log measures ship's  
The relative motion causes the Doppler shift  
and the ultrasonic waves reflected at the  
watermass (plankton or any underwater  
objects) are received at the frequency of fr =  
fo + fd where fd is the number of frequency  
shifts counted at the receiver circuit. To  
calculate ship’s speed, the following formula  
is used.  
speed by using the Doppler Effect, which is  
observed as a frequency shift resulting from  
relative motion between a transmitter and  
receiver or reflector of acoustic or electro-  
magnetic energy. A common example of the  
Doppler Effect is a train. When a train is  
approaching, the whistle has a higher pitch  
than normal. You can hear the change in  
pitch as the train passes.  
V = fd/fo • c/2sinθ  
c: Underwater velocity  
The DS-80 has a pair-beam, one directed in  
the fore direction and the other in the aft  
direction, which emits ultrasonic waves at  
an angle of θ to the waterline towards ship’s  
fore and aft directions. The frequency of the  
received signal is then compared with that  
of the transmitted frequency to measure  
doppler shift to calculate ship’s speed.  
Note that the sound velocity in water  
changes with water temperature and water  
pressure but the DS-80 readout is  
automatically compensated for change by  
using a temperature sensor.

REMARKS ON USAGE  
The accuracy will not be affected by:  
- water temperature (sound velocity)  
salinity  
Remarks on Usage  
The DS-80 measures ship’s speed by  
detecting the Doppler shift frequency of the  
echo reflected by a watermass (water layer  
containing plankton and other micro-  
pitch/roll ±10°  
organisms) located within the measuring  
area, which is usually about 2 m. In some  
instances, however, no signal is returned  
because of too few plankton in the sensing  
depths. This phenomenon can occur in  
particular areas in particular seasons. The  
probable cause is the plankton are lying in  
deep water because an ice-melted cold  
water mass covers the sea surface. Similar  
cases may also occur in a freshwater lake.  
Under these circumstances the DS-80 will  
not show the correct ship’s speed.  
Beware of Transducer Location  
The transducer may be damaged if it hits  
the dry dock blocks. Take the following  
measures to prevent damage to the  
transducer.  
1. Before delivering the ship, draw up a  
suitable docking plan taking into  
account the dimensions and location of  
the transducer. Store the plans onboard  
the ship.  
2. Place the dry dock blocks according to  
the plan.  
Conditions Affecting the  
Accuracy  
3. Have a diver check the position  
between the transducer and the blocks  
before removing the water. Confirm that  
the transducer will not touch the blocks.  
(with ref to IMO A.824/3.3)  
The Doppler speed log DS-80 is designed for  
reliable and accurate performance through  
FURUNO’s long experience and advanced  
technology. It operates on the best choice of  
system frequency and power output. As far as  
the sonic energy is used, the performance  
(accuracy) may be reduced or even lost  
under:  
rough weather (may be sea state 6 or  
severer)  
improper location of sensor, e.g., too close  
to the propeller, thrusters, drain tubes, echo  
sounder transducer

ANALOG DISPLAY UNIT  
CORRECTION DIAGRAM AT EXTREME TEMPERATURES  
Doppler Speed Log DS-80  
CORRECTION FACTOR FOR ANALOG DISPLAY MF-22A-1  
Example:  
If the analog speedometer reads 14.2 kt at a temperature of –15°C, the correct speed  
through the water is 15 kt. Failure of correction in low temperature can result in a maximum  
error of –0.8 kt or 5.3% for 14.2 kt readout. IMO limit of ±2% is exceeded over 10.0 – 30.0 kt  
reading but correction by this graph brings a correct measurement.  
At +55°C, an error of +0.0 kt (+2.7%) occurs at a speed of 30 kt; no other point IMO limit of  
±2% is exceeded.  
When the digital display and analog display readouts are different, take precedence of the  
digital readout. At temperatures 0°C to 50°C, the speedometer never exceeds the IMO  
limits.

Parts List  
This equipment contains complex modules in which fault diagnosis and repair down to  
component level are not practicable (IMO A.694(17)/8.3.1). Only some discrete components  
are used. FURUNO ELECTRIC CO., LTD. believes identifying these components is of no  
use for shipborne maintenance; therefore, they are not listed in this manual. Major modules  
can be located on parts location photos on the preceding page.
