Fiber-Optic Gyrokompasset
No Moving parts
No Maintenance required
High dynamic accuracy
Short setting time
Heading, roll, pitch and rate sensor
Per R. Bodin
The new Fiber-Optic Gyrocompass is the
first solid-state, fully electronic digital
gyrocompass system for marine
application in strapdown technology,
designed for highly sophisticated
integrated bridges and advanced
high-speed vessels
Per R. Bodin
The function of the Fiber-Optic Gyrocompass
is based on the so-called Sagnac Effect.
Here, a fiber-optic coil is used as a very
sensitive rate sensor, which is capable of
measuring the speed of rotation of the eart.
A combination of three such fiber-ptic coils
and two electronic level sensors is able to
determine the direction of true north.
Per R. Bodin
From the three rate of turn signsls and the
information from the level sensors a
sophisticated Kalman Filter computes the
direction of the rotation of the earth from
which geographical north is derived.
Per R. Bodin
Designed in strapdown technology, the fiberoptic gyrocompass is attached directly to
the vessel, eliminating the use of a gimbal
system. This arrangement has the
advantage of not only supplying heading
information but also roll, pitch and rate of
turn about all three axes.
Per R. Bodin
The fiber-optic gyrokompass can also be
used as a sensor for stabilizer system not
only on merchant marine vessels but also
on hydrofoils or catamarans.
Per R. Bodin
The extremely short setting time of only 30
minuts will be of great advantage for fast
ferries.
The fiber-optic gyrokompass is a complete
solid-state design with no rotating or
moving parts, with a very high reliability
(MTBF) and no maintenance
requirements.
