Avtrak 6
Description
AvTrak 6 is an acoustic navigation
and communications instrument
designed to form part of an
integrated AUV navigation system.
It combines the functions of
transponder, transceiver and
telemetry link in one low power unit
that has been designed to meet the
requirements of a wide variety of
AUV mission scenarios and vehicle
types.
The unit operates in Sonardyne
Wideband®2 or HPR400 Series tone
modes with a variety of other
acoustic systems and transponders. It
is also fully compatible with
Sonardyne’s family of survey quality
LBL and USBL navigation systems.
Avtrak 6 is available in three depth
versions: 3,000 m, 5,000 m and
7,000 m.
AvTrak has a comprehensive yet
easy to use command language that
allows the AUV to undertake
simultaneous LBL ranging, USBL
tracking via a surface vessel and
robust telemetry for AUV to vessel
and AUV to AUV communications.
This capability can be used to
provide absolute position reference
data to periodically update the
AUV’s inertial navigation system.
The instrument is available in a
variety of configurations with integral
or remote transducer options. This
flexible configuration is intended
both to assist the AUV manufacturer
with mounting of the instrument
within the AUV and to ensure the
highest levels of acoustic
performance.
The AvTrak6 supports a Sonardyne
Messaging Service (SMS) that allows
custom payloads to be transferred to
and from any 6G® transceiver. This
allows for vehicle configuration or
USBL position fixes to be acoustically
sent to the vehicle or for status
messages to be retrieved from the
topside system.
A number of acoustically controlled
digital I/O lines are also provided
for custom use, typical applications
include mission abort and emergency
ballast jettison control.
