Using Delph Nav Conducting a Survey
Quality Control of a Survey — Data Display Windows
Figure 21 shows the various data display windows offered by DelphNav for providing
quality control on incoming data strings and to help position the vessel relative to a
selected survey line. Display windows include:
• Single Beam Profile Display: capable of displaying both high frequency and low fre-
quency channels of a single beam echo sounder. Audible alarms may be set for an
operator-specified depth, with soundings below or above which cause the alarm to
trigger.
• Alarm Display: a large variety of alarm types may be specified in this window, with
both visual and audible notification when operator-specified parameters are exceeded.
Parameters related to the GPS, Heading, Attitude, and Single Beam data can be moni-
tored.
• Helmsman Display: shows position of vessel relative to the operator-specified survey
line. Parameters monitored include distance from SOL/EOL, off-line distance, course
to next waypoint, and navigation data recording status.
• Data Display: provides a text overview of the incoming data strings. Raw values, sta-
tistics, and quality parameters may be viewed for navigation, attitude, and single beam
data. X-Y graphs can be generated for any parameter within this window.
• Compass Display: shows heading information based on incoming navigation string or
other sensor data (for example, True Heading if gyro information received).
Each of these display windows and their associated options will be discussed in detail later
in this manual.
