Name: Warning Label (1)
Type: 86-003-1011-3
Code No.: 100-236-233-10
Warning Label
Warning label(s) is(are) attached to the equipment.
Do not remove the label(s). If a label is missing or
damaged, contact a FURUNO agent or dealer
about replacement.
CAUTION
If the optional rate gyro is installed, power
the system when the ship is stationary or
is traveling in a straight line.
The point of reference for the rate gyro is
determined when the system is powered. If
the ship is turning at that time, the point of
reference will be wrong and the gyro
indication in error. When the rate gyro goes
off (power outage, etc.), make sure the ship is
stationary or traveling in a straight line before
turning on the rate gyro.
CAUTION
If an LCD-type display is used, handle
the display with care.
The panel is made of glass which, if broken,
can cause injury.
Do not paint the transducer .
Paint causes a large drop in sensitivity.
Do not power the equipment when the
transducer is in air.
The transducer can become damaged.
Remove marine life from the face of the
transducer when the ship is dry-docked.
Marine life can affect sensitivity.
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.

1. GENERAL
The DS-30 is a highly-advanced, precision Doppler Sonar which incorporates FURUNO’s long
established ultrasonic technology.
It provides accurate displays of ship’s speed over a wide range from dead slow to maximum.
Speeds are detected relative to the ground or water both fore-aft and athwarthship. This feature
allows precise docking of mammoth tankers to oil loading/unloading facilities, as well as safe
navigation in narrow channels or straits.
Features
1) High measuring accuracy of ± (0.2% + 0.01 mm/sec) or better for low longitudinal speed, even in
shallow waters with under keep clearance as little as 1 meter, enables close control of speed and
safe berthing and anchoring operations.
2) Ground tracking up to 200 m provides accurate ship’s ground speed in most coastal waters.
3) Single hull unit composition with employment of the rate-of-turn gyro economizes installation
and maintenance costs. (Most other doppler sonars use two hull units: one each for measuring
ship’s transverse speed at the fore and the stern.
4) Rate-of-turn gyro uses optical fibers instead of moving parts, providing high reliability.
5) Logically arranged presentations of information on the color LCD for instant recognition of
ship’s motion and speed together with under-keel clearance, current and wind conditions.
6) GPS navigator connection provides ship’s ground speed at all times.
7) Conforms to the following standards: IMO A.824(19), as amended by MSC.96(72), IMO
A.694(17), IEC 61023, IEC 60945 (3rd edition), IEC 61162-1 (2nd edition)

1-2
Principle of Doppler Sonar
The Doppler sonar measures ship’s speed by utilizing the principle of the Doppler effect, which
defines that a signal emitted from a moving object heard with its frequency shifted at stationary
locations and the degree of the frequency shift is proportional to the speed of the moving object.
For ease of understanding, in this paragraph, measurement of ship’s fore-aft speed is explained.
Although the DS-30 employs three directional beams
as shown in the illustration on the preceding page, let’s
suppose that only two beams are used as shown at
right.
Ultrasonic waves are emitted at an angle of θrelative
to water line toward ship’s fore and aft directions. If the
ship’s speed is “V”, the source of the ultrasonic wave
(transducer) approaches or goes away the reflecting
points on the seabed at a speed of Vcosθ.
This relative motion causes the Doppler shift and the
ultrasonic waves reflected at the seabed are received at
frequencies of “fo + fd” and “fo - fd” by the transducer.
In the processor unit of the DS-30, difference of “fo +
fd” and “fo - fd” are computed to extract only the
Doppler shift factor “fd”.
“fo + fd” – “fo - fd” = 2fd
Since the “fd” is theoretically given by
fd = 2Vcosθx fo/C (C: Sound velocity in water)
and fo, C and θare known, V can be calculated if the
“fd” is given.
Note that the sound velocity in water changes with water temperature and water pressure but the
change by water temperature is automatically compensated by using temperature sensor.

If the speed error occurs, the speed unit (kn, etc) is highlighted in red
until the normal state is restored.
The ship’s course through-the-water or over-the-ground (true course)

Water
Yes Speed and direction relative to
ground. Ship’s over-the-ground
speed derived from a nav sensor is
used to calculate the speed and
direction.
If the current data is defective, the speed unit (kn, etc) is highlighted

The water current/tide measurement depth and water tracking depth
are set to the same depth (2m) at the factory. Therefore, the current
differential reading is normally 0.0 knots and 0 degrees. To get the
current differential reading, set the measurement depth deeper than the
water tracking depth by at least several meters, on the parameter menu.
