Acoustic Signal
Information carried by sound pressure waves through water. The Sonardyne acoustic signal
has a finite length.
Acoustic
Responder
An instrument that emits an acoustic signal in response to an electrical signal carried to it by
cable.
Acoustic
Transceiver
An instrument that emits and receives acoustic signals, and extracts information from them.
Transceivers can measure the time it takes a signal to travel from its transducer to a
transponder and return. Some can encode and send data in a message and extract digital
data from a message (Acoustic Telemetry). Used on a surface vessel or to mark a point on
the seabed, or fixed to a mobile for tracking or positioning.
Acoustic
Transducer
A device that converts electrical signals into acoustic signals and vice versa.
Acoustic
Transponder
An instrument that emits an acoustic signal when it detects an interrogating acoustic signal.
CMOS
Complementary Metal Oxide Silicon. A major integrated circuit technology based on
combinations of p-channel and n-channel field effect transistors fabricated on the same
silicon substrate. Especially attractive in low-power applications since the basic CMOS
logic gate only consumes significant power during switching.
COMPATT
COMPuting and Telemetry Transponder
Common Reply
Signal (CRS)
A reply signal common to a complete family of addressed transponders.
CPU
Central Processing Unit
DAS
A micro-controlled data acquisition and logging sub-assembly located within a transponder.
Delay between
commands
Provides a delay between adjacent commands.
Depth Status
The transponder can be fitted with an optional depth sensor to send depth information at
each interrogation.
Firmware
The firmware installed on the transponder. Firmware updates can be installed via 6G
Terminal Lite. The Tx firmware refers to the transmission signal synthesiser.
Long Base Line
Positioning
System (LBL)
A system where two or more transponders are on the seabed. The positions of the
transponders are established by a calibration process in a seabed frame. The distances
from a transducer to each transponder are measured using a transceiver. The position of the
transducer can be computed in the seabed frame. The name comes from the “baselines”
joining each transponder.
LUSBL
Long and Ultra Short Base-Line
PSU
Power Supply Unit
QR code
Quick Response Code. A matrix barcode of black modules arranged in a square grid on a
white background.
ROV
Remotely Operated Vehicle
Sonardyne
