The FURUNO DS-50
is a Doppler Speed Log
designed to meet the IMO Resolution, IEC
specifications and other national regulations. Its
three-beam transmission reduces the effect of pitch
and roll for high accuracy and enables the
measurement of port-stbd speed as well as fore-aft
speed. Keel clearance information is provided to
assist with shallow water navigation.
The DS-50 measures and displays the ship's over-the-
ground or through-the-water speed based on
the Doppler effect. Speed data can be output to
external equipment such as ARPAs, INS and IBS.
There are three operation modes: Ground-tracking,
Water-tracking and Auto. The Auto mode
continuously displays ship’s speed, switching
between Ground-tracking and Water-tracking
automatically.
The DS-50 consists of a display unit, processor
and transducer. The compact design of the display
unit allows flexible installation on the bridge. For
monitoring at remote locations, analog and digital
indicators are optionally available.
