Datasheet
iUSBL Transceiver (Inverted)
Description
Inverted USBL, or iUSBL, builds on
the success of Sonardyne’s Fusion
platform and utilises a 7,000 metre
rated inverted transceiver located on
the vehicle, to offer high
performance subsea positioning for
ROVs, AUVs and deep-tow bodies.
Sonardyne’s family of Fusion Ultra-
Short Base Line (USBL) transceivers
support the use of modern
Wideband™ signal technology,
offering improved noise immunity,
increased dynamic range and
greater accuracy.
As well as providing all the standard
features of Sonardyne’s well proven
USBL technology (see separate
datasheets for Type 8021 & Type
8023 transceivers), the Type 8091
Inverted USBL transceiver provides
the added flexibility of being able to
mount the transceiver on an AUV,
ROV, or deep towed body for use up
to full ocean depth. Mounting the
transceiver in this way offers many
operational benefits. Installation is
simple when compared with
installing a through-hull or over-the-
side USBL transceiver.
iUSBL Positioning Technique
Vehicle mounted transceiver positioning
a vessel mounted transponder
The transceiver can be mounted at
any angle from horizontal to
vertically upwards allowing
innovative, previously difficult
tracking operations to be carried out,
e.g. towed body to streamer
tracking, ROV to ship tracking etc.
Key features
•
Full ocean depth rated USBL
transceiver
•
Can be mounted on an AUV, ROV
or deep towed body
•
Incorporates Sonardyne’s latest
Wideband Technology
•
Non-Sonardyne frequencies
supported
•
No need for second vessel to
position the towfish
Closely coupled attitude sensors
eliminate the need for repeated
system calibration, whilst the
accuracy and repeatability of the
acoustic signals are improved, as the
transceiver is located in a low noise,
dynamically stable environment.
