Datasheet
Fusion USBL Transceivers
Description
Sonardyne’s family of Fusion Ultra-
Short BaseLine (USBL) transceivers
support the use of modern
Wideband signal technology,
offering improved noise immunity,
increased dynamic range and
greater accuracy.
The Type 8021 transceiver offers a
hemispherical pattern of acoustic
coverage whilst still ensuring
rejection of vessel noise. The
transceiver allows tracking of targets
from below and to the side of the
vessel and it is suitable for a wide
variety of survey tasks such as
towfish tracking and ROV
positioning.
The Type 8023 transceiver is
optimised to receive signals arriving
within a ±50º cone. Any noise
generated outside of this area, for
example by thrusters, is attenuated
further, therefore improving the
signal to noise ratio and so the
positioning accuracy.
In practise, this has been proven to
allow the accurate positioning of the
noisiest vessels. On quieter vessels, it
enables even deeper depths to be
achieved.
The all new hardware platform on
which the Fusion USBL transceivers
are based means that the units can
be easily upgraded remotely via a
serial interface.
They can also be used as Medium
Frequency Long Baseline (LBL)
transceivers when required. This
removes the cost and inconvenience
of installing and setting up a
separate LBL transceiver when the
need arises.

The absolute accuracy of the system is dependent upon the quality of attitude
and heading sensors, beacon source level, vessel noise, water depth,
mechanical rigidity of the transceiver deployment machine and proper
calibration of the total system using CASIUS
