Description
The Nano Responder is specially
designed for accurate positioning of
small ROVs and tracking of small
AUVs.
For ROVs, the responder is triggered
by a signal generated by the USBL
system and sent down the ROVs
umbilical. For AUVs either the AUVs
navigation system can generate the
trigger, or a future option will be to
put the Nano Responder into a
pinger mode. When triggered, a
Wideband signal is transmitted
acoustically enabling Sonardyne’s
USBL systems to calculate the
position of the vehicle.
The Nano Responder is fitted with a
pressure sensor to measure the depth
of the instrument and this is encoded
into the Wideband acoustic signal
sent back to the USBL system. The
depth information is used by the
USBL system to enhance the
positioning solution.
The standard instrument is 500 m
depth rated and has an acoustic
source level and beam-shape that is
designed to operate over a 750m
slant range under normal conditions.
A 5-pin connector is used to supply
power from the ROV (nominally 24V
DC) and to connect the responder
trigger line.
The Nano Responder operates in the
upper Medium Frequency band and
so is compatible with the following
Sonardyne Wideband USBL systems:
Scout Pro, Ranger, Fusion and
Marksman.
An additional feature is the ability to
change the operating parameters
using an optional serial interface to a
PC running set-up software. The
parameters which are under operator
control include: acoustic transmission
signal, turn-around time and depth
reply on or off.
Test functions via the serial port
include: read status, read depth
sensor and initiate acoustic signal
transmission.
