The
Chelsea Technologies Group offers a custom design and manufacture
service for acoustic telemetry systems and acoustic modems. We have
designed and manufactured custom telemetry systems and modems for both
commercial and military customers. Companies
using the Chelsea systems include BAeSEMA and GEC-Marconi as part of
their exercise mines, which are used for training mine hunting crews.
These acoustic telemetry / modem systems are in-service with the United
Kingdom, United States of America, Canadian, Australian and Belgian
Navies. Chelsea Technologies Group telemetry systems have covered
frequencies from 8kHz to 60kHz, and been used for applications such as
data transfer and complex telemetry. All these systems have optional GUI (Graphical User Interface) control systems running under Windows NT4 or 95/98, which have been developed to provide easy control of these advanced acoustic telemetry systems. |

The
Chelsea Technologies Group offers a custom design and manufacture
service for sonar systems and sonar system components. Active sonar and
passive sonar systems are supplied for both surface ships and
submarines. These are produced to cover functions such as intercept,
navigation, obstacle avoidance and high power tracking pinger output. Sonar equipment designed and manufactured by the Chelsea Technologies Group Ltd is included in many UK submarines as the outboard components of Sonar 2077. Chelsea also offers technical and logistics support to the UK MOD, DERA, etc. for both in-service and new-generation sonar systems. |

Chelsea
offers a custom design and manufacture service for acoustic synchronised
pinger and triggered pinger systems. Chelsea
Technologies Group Ltd supply the STAB4 towed synchronised pinger
system, which is used on the BUTEC underwater, tracking range in
Scotland. This advanced pinger system, which was designed and developed
for the UK DGUS, can be towed up to a speed of 25 knots and can be
commanded using acoustic telemetry from a surface vessel. |
|
It
is a fully synchronised system and achieves a timing accuracy of better
than 200 microseconds over its 12-hour battery life. Chelsea
Technologies Group Ltd also supply tracking pingers for use on the Rhona
range in Scotland, this system mounts within the 'sea chest' of
submarines. Torpedo recovery pingers have also been designed and
manufactured for several different torpedoes. |
|
|
Chelsea
Technologies Group Ltd also produces a PC-based portable synchronised
pinger and receiver system, or Distance Measurement Equipment (DME), for
use on submarines or surface ships. This slant range processor and
synchronised pinger system can be interfaced with a vessel's sonar to
provide a synchronised pinger or a synchronised receiver that can
display slant range. |
Slant Range Processor...
|
|
In
DME (Distance Measuring Equipment) mode, VASS can transmit or receive
underwater acoustic tracking pulses. This system is used to measure the
slant range between the towed body of VASS and the vessel under test. So
that the vessel under test can display the slant range a Remote DME unit
is provided which has all the digital signal processing and
synchronisation equipment mounted within a PC.
The configurable parameters are controlled via an easily operated
Graphical User Interface, running under Microsoft Windows 95/98/NT4 |

The
Chelsea Technologies Group offers a custom design and manufacture service
for sidescan sonar arrays and the electronic and processing systems
associated with sidescan sonar arrays. We specialise in designing and
producing state of the art sidescan sonar arrays and interferometers for
integration into OEM systems. |
|
|
|
. Sidescan sonar arrays from the simple to the very complex have been supplied to organizations such as Ultra Electronics, C-Max, Sonar Equipment Services and the UK Navy. Sidescan sonar array designs are available covering frequencies between 60kHz and 700kHz. |

Piezocomposite Sidescan Sonar Array |
| ... |
 |
. |
| We recently announced the availability of the first commercially priced piezocomposite high-resolution sidescan sonar array. Offering improved beam pattern stability and ultimately higher resolution than conventional monolithic sidescans, piezocomposites promise to revolutionise the sidescan manufacturing industry. The launching of piezocomposites for imaging sonar follows on from our recent development of high frequency piezocomposites in conjunction with the UK's Defence Evaluation and Research Agency (DERA). | |
