Lightweight Actuation Transponder (LAT)
Description
Part of Sonardyne’s Coastal Acoustic
product range, the Type 8044
Lightweight Actuation Transponder
(LAT) is a low cost acoustic device
that provides cable-less, through
water control of subsea electrical
equipment. Applications for the LAT
include activating the inflation of
buoyancy bags and opening or
closing valves. The LAT can also be
interrogated from the surface to
determine its position on the seabed
and provide confirmation of
electrical activation.
The output from the LAT can be
configured to provide multi-width and
multi-pulse electrical outputs to suit a
wide range of requirements. A
rugged underwater connector
ensures reliable activation.
The LAT is remotely controlled from
the surface using a low-cost deck unit
supplied with a dunking transducer
and 10 metres of cable. The deck
unit is used to program the acoustic
identity of the LAT from several
thousand available and then test the
unit prior to deployment. Once in the
water, the deck unit can measure
ranges to the transponder and after
sending a secure actuation
command, relocate the transponder.
Key Features
• Provides acoustic command and
control of subsea electrical devices
• Configurable signal output to suit
customer electronics
• Depth rated to 500 Metres
• Up to 4½ years deployment with
Long-life Lithium battery pack
• Rugged, compact design
• Robust underwater connector
• Thousands of secure identities; field
programmable with deck unit
• Compatible with ROV-Homer and
Homer-Pro relocation systems and

system
LATs are also compatible with
Sonardyne’s ROV-Homer and Homer-
Pro target relocation systems.
Deployed at a point of interest, the
LAT can be interrogated, weeks or
years later, to provide range and
direction guidance to a ROV pilot or
diver wishing to home back on to it
.
