Refer to Observation Systems for more information on Observation System parameters.

Click on Raw Data and then Observations Systems.

Click on

.

Select a System and an associated Observation.These are the Observation Systems supported:

- Gyro Compass
- Underwater Sensor
- Speed Log
- Tide Gauge
- Surface Navigation Systems

- Magnetometer
- Miscellaneous Systems
- Dredging Sensor
- Rotation Angle Sensor
- Acceleration Velocity Sensor

Add Backfill Flag and Dredging Status from these choices in our example:

Select which Sub Items to show for each observation. In our example only the Value is added.

Set the Properties for each sub-item.

Click on

multiple times to add the Observation Systems and Observations shown below. For each add the Sub Item 'Value'.

Highlight for example, the Computed Pitch, Sub Item 'Value'.

Click on the Display drop down arrow and select User Defined. This changes the options under Properties by adding a line.

Click on the browse button

to open the User Defined Format Specifier dialog.

Modify the Display Specifier as shown above.

Click on

to check what will be finally displayed is what you want.

Click OK.

Multibeam Echosounder

List with all available multibeam and multi-transducer echosounder systems that exist in the current selected QINSy database.
Because different types of multibeam echosounder systems are supported (Ro/Theta, X/Y/Z, Profilers) and multi-transducer systems, some items below may not be applicable for the particular type.

No multibeam echosounder is defined in our example.
These are the Sub Items:

Positioning

Display of spud pole and dredge tool positions are to be added; however, positioning here refers to raw data and results data is preferred.
These are the raw data sub-items:

USBL

QINSy may be receiving positions of spud and/or bucket in the form of pseudo USBL measurements, i.e. a dX/dY/dZ measurement from the dredger's reference point to the spud and/or bucket. Displaying these measurement may be useful, especially the range to the spud pole.
