4 - Position Information Display

The Position Information Display is located at the top left of the sonar image and provides the user with the current position data for the ROV.

The Status Indicators located across the bottom of the user interface comprises many user-friendly elements, including the current navigation information, status indicators and flight mode.

4.1 Position Information

This position information panel provides the user with the following ROV information:

Range to mouse cursor position
Bearing to mouse cusror position
Depth (D)
Heading (H)
Bearing to target (when tracking is active)
Range to target (when tracking is active)

4.2 Status Indicators

The status indicators on the position information display allow the user to monitor the status of the ROV.

Figure 4 - Status Indicators

4.2.1 The DP Status Indicator

This indicator displays the status of the DP system:

The indicator is green when the DP system is running.

Figure 5 - DP System Running

The indicator will not be illuminated when the DP system is not running. In this instance, the sonar will not be able to find or lock to a target.

4.2.2 The Position Status Indicator

This indicator is illuminated when the ROV is within the tolerance range (typically a few meters of its target position. The indicator is not displayed when the ROV is not in position.

4.2.3 The Joystick Indicator

This indicator is displayed when the system receives a command from the joystick. The indicator is not displayed when the joystick is not considered to be in use.

If the joystick movement is within the specified deadband range, the system will not detect the command. For example, a joystick movement of 20% will not be detected by the system if the deadband setting is 30%.

4.2.4 The Navigation Status Indicator

This indicator can have four different displays, depending on the accuracy of navigation system and the ROV's global reference:

INDICATOR APPEARANCE	STATUS
Figure 8 - Navigation Indicator	The navigation system is in its "RUNNING" mode, and operating correctly, and the system can calculate relative positions to target.
Figure 9 - Position Indicator	The navigation system is not operating at an adequate level of accuracy and is no longer reliable. Only the MANUAL flight mode is accessible.
Figure 10 - Nav Fault Indicator	The navigation system has failed. Only the MANUAL flight mode is accessible.
