Monitor/Keypad
A monitor contains a 12 inch colour graphics display and has a
keypad for operator input.
A later version of this unit has a 17 inch high resolution
monitor. The monitor and keypad are split into two separate
units. Both are designed for 19 inch rack mounting
Marine Riser Angle Monitoring System
(MRAMS)
Used for measuring the angle between the Blow-Out Preventer
(BOP) on the seabed and the Riser.
Navigation Sensor Hub (NSH)
The NSH is the interface between the in-water acoustic
instruments, sensors and the Navigation Computer which runs
the acoustics positioning software.
Remotely Operated Vehicle (ROV)
A vehicle controlled and powered by a cable connection so it
can travel between the sea surface and the seabed
Heading, Roll and Pitch (HRP)
Is a compensated vessel frame. This is a frame sharing the
same origin as the vessel frame but with the z axis vertical and
the y axis parallel with a meridian passing through the origin
(points true north)
Seabed
The surface of the earth covered by sea water. The seabed is
considered stationary
Spread Spectrum (SS)
Spread-spectrum techniques are methods by which a signal
(e.g. an electrical, electromagnetic, or acoustic signal)
generated in a particular bandwidth is deliberately spread in the
frequency domain, resulting in a signal with a wider bandwidth.
These techniques are used for a variety of reasons, including
the establishment of secure communications, increasing
resistance to natural interference and jamming, to prevent
detection, and to limit power flux density.
Unit Identification Number (UID)
Each product produced by Sonardyne Int Ltd contains a unique
24bit address. It is denoted by 6 hexadecimal characters.
Wideband Test Terminal (WTT)
PC software for testing 6G transponders and transceivers.
Sonardyne Wideband®2
6G® transponders and transceivers use Sonardyne
Wideband® 2 which has ultra-wide bandwidth signals giving a
faster and robust transmission of data, more precise ranging
and mitigation from multipath in shallow water and amongst
steel structures in deepwater.
6 Generation (6G®)
6G® technology gives a better performance, easier to use,
more functions, equipment flexibility and compatibility with
aided inertial technologies.
