Datasheet
Autonomous Monitoring Transponder (AMT)
Description
The Type 8305 AMT is an extension
to the functionality provided by
Compatt 5 (extensively used for
subsea survey tasks) but with unique
autonomous (without surface control)
acquisition of acoustic ranges and
sensor data. The data is time-
stamped and logged internally for
recovery via the integrated high-
speed acoustic telemetry modem. The
autonomy allows measurements to be
made over a long period of time
without a surface vessel or ROV
being available to command the
process. This enables new
applications that save vessel and
survey time so reducing cost and risk.
Precision sensors (pressure, temp,
sound velocity and dual-axis
inclinometers) are integrated and are
intelligently powered up at the
requested time and sampling period,
providing an ultra-low power
platform for up to three years
deployment, including recovery of all
data via telemetry. Sampling regimes
can be re-programmed remotely via
the telemetry link.
The AMT has many of the same
acoustic functions as Compatt5,
operates in the Medium Frequency
band and is fully Sonardyne
Wideband® compatible.
The AMT is available with a range of
transducers (omni and directional),
depth ratings and pressure housings
dependent on deployment duration
and application. Additional sensors
can be easily integrated externally
via the power and communications
port.
