1.3 Surface Equipment
The surface subsystem comprises the TPU and the SonarPro Workstation. In
addition, an optional motion reference unit can be connected for measurement of
pitch, roll, yaw, and heave, as well as GPS for location, a heading sensor for ship’s
heading, and a CTD.
Transceiver and Processing Unit (TPU).
The TPU is shown in Figure 1-1.
The main power switch is located on the lower right corner of the front panel.
The TPU is rack mountable in a standard 48.26 cm (19 inch) rack and contains
electronics for receiving sonar data, downlink multiplexing of control signals
to the Sonar Head Unit, and uplink demultiplexing of sonar and auxiliary
sensor signals.
SonarPro Workstation.
The SonarPro Workstation is shown in Figure 1-1.
Most operator functions are accomplished through the use of the SonarPro
Workstation which supports the PC based Windows operating system and runs
SonarPro. SonarPro provides the operator interface to the HydroChart 5000
Sonar System. SonarPro is a comprehensive software package developed to
support survey planning; data visualization and quality control; target
management and data recording; and playback. SonarPro also performs the
side scan and bathymetry data processing. Data can be logged in SDF, GSF or
XYZ format. These formats are supported by most third party post-processing
software applications. In addition to processed data, raw stave data can be
logged together with all motion, navigation, and heading and sound velocity
data. This permits reprocessing of both side scan and bathymetry data in a
post-processing environment. For more information on the computer, refer to
the manufacturer's manual.
1.4 Subsurface Equipment
The subsurface equipment comprises the Sonar Head Unit, as shown in Figure 1-2
on page 1-5, and a deck cable. In addition, an optional sound velocity sensor can
be included for measurement of surface sound velocity.
Sonar Head Unit.
The Sonar Head Unit is shown in Figure 1-2. It consists of
the sonar electronics, the transducers, the sonar altimeter, a support frame,
interconnect cables, and fairings. An optional sound velocity sensor and cable
can also be installed in the Sonar Head Unit.
Deck cable.
The deck cable is a complete assembly consisting of a coaxial
cable in a Kevlar reinforced light weight Polyurethane jacket.
