SECTION 3 Setup and Deployment Predeployment Checks
Data Telemetry and Sensor Tests
With the tow vehicle activated, perform the steps listed below to verify the
receipt of the navigation and sensor data, and to verify the correct operation
of the pitch, roll, and heading sensors.
1. Click Diagnostics in the Sonar Controls box in the Main window. The
Sonar Diagnostics box shown in Figure 3-17 opens.
2. Select the Console check box in the Telemetry Output area of the Sonar
Diagnostics box.
3. Verify that there is pitch, roll, heading, and navigation data displayed in
the Status display.
4. While observing the pitch and roll indications in the tow vehicle Pitch and
Roll display, move the vehicle’s nose up and down several times. Then
rotate the tow vehicle slightly to starboard and to port several times.
Verify that the pitch and roll indications in the tow vehicle Pitch and Roll
display change accordingly. An example of pitch and roll data in the tow
vehicle Pitch and Roll display is shown in Figure 3-19.
Figure 3-19 Displayed Pitch and Roll Data
Moving the tow vehicle’s nose up produces a positive pitch with the pitch
indication sweeping to the right, and moving it down produces a negative
pitch with the pitch indication sweeping to the left. Similarly, rotating the tow
vehicle to starboard produces a positive roll, and rotating it to port produces
a negative roll. The roll indication sweeps right and left, respectively.
