FOREWORD
Foreword
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.
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.
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.
This equipment is designed, produced and
documented by FURUNO Electric Co., Ltd.,
complying with ISO 9001 standards as
certified by the Lloyd’s Register of Quality
Assurance System.
Features
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.
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.
• 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
adjustable-contrast LCD display.
• Analog display, digital Indicator and
digital distance indicator display
optionally available.
• Conforms to the following standards: IMO
A.824(19), as amended by MSC.97(72),
IMO A.694(17), IEC 61023, IEC 60945
(3rd edition), IEC 61162-1 (2nd edition)..

PRINCIPLE OF OPERATION
The Doppler speed log measures ship's
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.
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.
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.
V = fd/fo • c/2sinθ
c: Underwater velocity
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
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-
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.
Conditions Affecting the
Accuracy
(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
• depth under the keel if less than 3 m
The accuracy will not be affected by:
• - water temperature (sound velocity)
• salinity
• pitch/roll ±10°
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.
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.

"AUTO" position indicates a Doppler speed
(SDME) but if the DS-80 fails, a GPS speed
will be indicated.
Note 1: If the log speed fails, the display
unit reads a GPS speed, but speed data will
not be output to other equipment.
Note 2: Doppler speed is used to calculate
speed when both DOPPLER and GPS are
abnormal in AUTO.

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.

3 MAINTENANCE, TROUBLESHOOTING
WARNING
ELECTRICAL SHOCK HAZARD
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
3.1 Maintenance
3.1.1 Preventive maintenance
Check the following points regularly to
maintain performance.
• Check that the connectors on all units of
the system are firmly fastened and free of
rust. Clean if soiled or corroded.
• Check that all ground wires are tightly
fastened.
• Dust and dirt on the display unit including
the screen may be removed with a soft
cloth. Do not use chemical cleaners to
clean the display unit; they can remove
paint and markings.
3.1.2 Transducer maintenance
Marine life (barnacles, etc.) adhering to the
transducer face will reduce sensitivity.
Periodically remove any marine life from
the transducer face with fine sandpaper or
a piece of wood.
CAUTION
Do not paint the transducer.
Painting will affect performance.
3.1.3 Fuse replacement
Fuses in the units of the system protect the
electrical circuitry from burning by
overcurrent. If the equipment cannot be
energized check the fuse in the power
cable connected to the display unit. Locate
the cause before replacing the fuse.

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.
