SyQwest Bathy 2010 vs. Competition



The Bathy 2010 and competitors products are rack
-
mounted solutions for Sub
-
Bottom profiling
and Deep Ocean Bathymetry applications. The Bathy 2010 product was designed and developed
to offer a new generation of single
beam Sub
-
Bottom profilers that provides the latest available
technology.


There are many system enhancements that have been included in the new Bathy 2010 design but
a few significant advances that differentiate it from the Competition are described below:


1.

Signal Processing Hardware


The Bathy 2010 has incorporated the latest available
electronics hardware in the design of its signal processing function on both transmit and
receive sides of the processing. The hardware core of the signal processing funct
ion
includes:



24 bit Delta Sigma A/D converter for receiving and digitizing acoustic signals



Dual, 32 bit floating point DSP processing architecture



1MHz sampling D/A converter for high resolution transmit signal synthesis.



Software selection of up to 4
frequencies per channel (1KHz


200KHz).



Dual Channel(optional), Simultaneous data acquisition


Our competition incorporates 16 bit technology and a fixed point DSP for their signal
processing engine. This limits the processing power available and consequ
ently affects
the resolution of the data and the overall capabilities of the system. The Zoom modes
described in the next section are one example of a time consuming function that could
overload a 16 bit, fixed point processor.


2.

Acoustic Display Features



The Bathy 2010 system interface was the most important
feature considered when the new product design was specified. The previous generation
product, the Bathy 2000, was long considered a product that produced high quality Sub
-
Bottom data in shallow, m
edium, and deep ocean depths. However, the interface to the
user was not always the easiest to work with. Bearing that in mind the designers at
SyQwest specified a GUI (Graphical User Interface) that is easy to use and provides the
features that most sci
entists have requested over the years. The following Display
functions are included in the Bathy 2010:



Bottom Zoom Mode



This mode provides a second display window that allows
the user to look at an expanded view of the acoustic data in the area of the o
cean
bottom. It provides the detailed view of the bottom area so the user can make any
system adjustments to optimize the collection of the sub
-
bottom data. The view
in this mode is automatically phased up and down the water column in
conjunction with th
e bottom depth so the it can be used in a hands free manner.
This can be done while still also viewing the entire water column of data in the
normal window. It makes data acquisition and system monitoring much easier to
do in moderate to deep water situa
tions.

Bottom Lock Zoom Mode


This mode is similar to Bottom Zoom as described
above except that the bottom slope is removed from the zoomed data so the
presentation shows a bottom line without any contour. In steep slopes and certain
other geophysical

conditions this mode is very useful.



Marker Zoom Mode


This mode is similar to the other Zoom modes as
described above except that the starting point for the Zoom window is determined
by a selection made by the user. It is useful for applications where
the depth does
not vary much over time and the user wants the Zoom window view to reflect the
same area of the water column throughout the survey.



Shift Range Function
-

The Shift Range function is particularly useful for Sub
-
Bottom profiling systems as it

allows the user the flexibility to change the range
window in small increments so all of the Sub
-
Bottom data can be displayed for
viewing. Certain combinations of Range selection and Bottom depth result in the
display showing truncated sub
-
bottom data at

the deeper end of the range. By
using the shift range feature the user can set the range window in small
increments (1 foot or meter in shallow, and 10 feet or meters in deep) to rectify
the issue. Keeping the range value as small as needed ensures tha
t the data
acquisition rate is set to the highest rate possible.



Snap Shot Feature


The Snap Shot feature of the Bathy 2010 allows the user to
save an instantaneous screen capture of the entire Graphic display to a standard
JEPEG file for historical use.

The single click function simplifies the efforts of
the users when trying to capture interesting features within the display windows.


3.

Power Amplifier Output


The power output level of the B2010 system is generated by
the SyQwest Linear Power Transmitter

(LPT) unit. The unit is equipped with a true 10
Kilo Watt (20% duty cycle) capable amplifier. The unit allows for standard systems to be
shipped with the capability of processing 50msec CHIRP pulses, which provides a higher
signal processing gain and su
perior sub
-
bottom resolution in moderate and deep depths.
The amplifier and system is also capable of supporting 100msec for special applications.
The LPT Amplifier module has been newly re
-
designed in the last year making use of all
the latest in power
device technology. The Power amplifier from SyQwest has been used
in a number of Single Beam and Multi Beam applications successfully. The design,
capability and reliability of the SyQwest B2010 Amplifier unit is definitely better than
the Competition.

I
nstallation Support


The installation and field support team at SyQwest Inc. has over
100 years of cumulative experience in the design, installation, and support of wet end
acoustic systems on a large variety of vessels. SyQwest Inc.’s team (as Ocean Dat
a
Equipment Corp.) was responsible for the design and installation of an ice
-
hardened sea
chest that was installed on all the US Coast Guards Polar Icebreaker Healy. The
SyQwest under hull group also design and supervised the installation of the sea ches
t
designs for the US Naval Oceanographic research office TAGS class of ships (6 Ships).
Three of the AGOR class vessels have SyQwest sea chest designs incorporated (Ron
Brown, Atlantis, and Roger Revelle). SyQwest has also designed sea chests and through

hull installation packages for ships owned by allied foreign countries. The top side
electronics support at SyQwest is second to none as well. Our electronics support group
offers the same level of experience as the under hull team and is always availab
le for
phone, email, or on
-
site support for our customers. None of SyQwest’s competitors have

the cumulative experience in both areas of design and support. Specifically, for ship’s
under hull solutions, our competitors in most cases have little or no ex
perience in this
area.
