4 OPERATION
System control
The control of the Kongsberg EM 3002 is done from the HWS
10 Operator Station using a standard click and point graphical
user interface. The software, Seafloor Information System for
Real Time Multibeam or SIS-RTM, may either be run under the
Microsoft Windows XP or Linux operating systems which are
both installed on the HWS 10. As a minimum the system
software includes the necessary features for system installation,
testing and running the multibeam. Ping related displays are also
included as standard, as is the capability of logging the acquired
bathymetry data. The user has the option of replacing most parts
of the advanced features of SIS with other software of his
choice.
The system does not require operator intervention during normal
operation, but tracks the bottom automatically while adjusting
mode, gain and range dependent parameters as required. Before
operation is started, the system and sensor installation
parameters must be defined, and the necessary external sensors
such as positioning system and vessel motion sensor connected.
Parameters critical to data quality are password protected, and
most parameters can be recalled from a disk file.
Quality control of the acquired data is done through graphical
displays. In addition a message window and alphanumeric
displays are included to allow a quick overview of system
status. The basic system includes the graphical displays required
for real-time quality control of the EM 3002, such as:
•
cross-track depth profiles
•
beam intensities and quality measures
•
time series display of beam samples and sensor values
•
3D waterfall display
•
sound speed profile display and editor
Unless other software is installed the operator will normally be
viewing gridded data in a geographically oriented 3D display as
his primary means of quality control of the survey. The grid has
six levels of detail allowing rapid zoom in and out. The 3D
graphics allows the seabed to be viewed from any direction, and
thus to for example highlight any differences between the
current and old surveys in overlapping areas.
