Reson Seabat 7K Head II (TCP Network) - 20

Available packet types

As discussed in the Database Setup chapter, different devices will support different record types. The following table shows which records used by Qinsy are supported for each device.

MBES

Time Tag
The time tag from the 7000 record's RECORD_FRAME is used as the ping observation time. 
Therefore it is crucial for proper operation that both the Seabat 7K unit and Qinsy are UTC synchronized (previously PPS).

Brightness and Colinearity
Brightness and Colinearity flags are decoded and used by Qinsy.

This translates into the following Quality indicators:

The driver will automatically use the 7027 message from the Seabat 7K when available.
This 7027 record contains the raw steered angles and travel times per beam.
When the 7027 message is not available (7K software Version < 7) then the driver will use the 7004 + 7006 messages.

Extra detection
The extra detections are stored in the Qinsy database, however there is no distinction between normal and extra detections and therefore they not stored in the *.qpd files

7027 message

The 7027 message doesn't contain a per-beam intensity for FP1/2/3 firmware. If this is detected the intensity is still decoded from the 7006 message.
The FP4 7027 message does contain intensity values and also supports multiple detections per beam.
Furthermore the 7027 contains a varying number of detections per ping, therefore the driver will (as of 24 Jan 2012) decode the number of beams from the 7006 message which is fixed to the maximum beam count, and leave the beams that were not reported by the 7027 message to invalid/0.
This was done to prevent any issues with GSF Export and Fledermaus usage that do not cope well with a varying number of detections per ping.

Reson FP4 Multi Detect Support

Note on Reson Seabat 7K FP4: Since version FP4 the Seabat can detect multiple detections (footprints) per beam.
Currently these are ALL decoded and used by Qinsy.

Teledyne Odom

Teledyne Odom MB2 Technical Note

Teledyne Odom has released a Technical Note on Increasing Network Adaptor Receive Buffer.
To prevent packet drops and poor performance the network adapter receive buffer (input buffer) must be increased to at least 512.
Read the technical note for further details.

Norbit

Interfacing Norbit with Qinsy

Norbit User Manual (TN-140075-4.1.0_WBMS-User_Manual.pdf) contains detailed information regarding Qinsy software configuration with the Norbit system.
See Appendix G&H.

When the system has a Applanix unit integrated, please double check in PosView if the 104 message is enabled.
The 104 message needs to be enabled to report position SD's (of Sensor 1) to Qinsy.  

Rotator

It is possible to use a Norbit in combination with a Rotator.
When the Rotator is turning, no data will be outputted from the Multibeam.

Side Scan

The side scan data is always decoded from the 7007 message.

The Seabat 7K Center software acts as a server, the Qinsy driver acts as a client. The driver will automatically connect to the Seabat 7K Center.

The driver will negotiate the required records automatically when connecting, for example it will always ask for record 7000. Different data types will be requested depending on the Raw Storage Settings (see Driver Specific Settings below) and configured system types.
The driver will start decoding data after the negotiation phase was successful. Note that thus it is not necessary to set any outputs within the Reson software.

The Reson 7K Software doesn't require any specific connection setup anymore, any previous UDP broadcasts can be removed in the user interface of the 7K software.

Info

Various packet types can be exported to XTF.
It is important to select the correct Raw Data Recording options in Database Setup before starting the survey!

Snippet window limitation option can now also be set in Database Setup - Driver Specific Settings.

Bathymetry / Snippets / Water Column

1. Add a new "Multibeam Echosounder" system to the object in your template database.

2. Select driver "Reson Seabat 7K (TCP/Network)" unless an Integrated Dual Head (IDH) system is used.
   In that case the port head should use the "Reson Seabat 7K (TCP/Network)" driver and
   the starboard head should use the "Reson Seabat 7K Head II (TCP/Network)" driver.

3. The port number should always be 7000, even if dual head systems are interfaced.

4. The IP address should be the IP address of the Seabat 7K System.
   For dual head systems different IP numbers are required unless an Integrated Dual Head (IDH) system is used.
   In that case the same IP address should be used for both heads. Examples of these are the IDH T50-R and T20-R systems.

   

• On the Seabat 7k Settings page we can select which raw packets are stored in the database:
  

  

1. System
   Select the system you are using with this driver. 

2. Packet storage for processing
   Here you can select which processing tool (if any) you want to use. When a specific processing tool is selected, the raw packets required by that tool are automatically stored in the database. 
   Only the processing tools which are supported by the device you are using are shown.
   Supported processing tools include:

   • FMGT - FlederMaus Geocoder Toolbox 

   • FMMW - FlederMaus Mid Water

   • XTF - Processing tools that can handle eXchange Triton Format import (CARIS / PDS / etc.)

Grayed out

When FMGT is selected the snippets will be grayed out because the format is automatically selected.

This also applies to FMMW (water column).

3. View data in Qinsy
   Here you can select if you want to view water column or snippet data in Qinsy. Some devices support multiple types of data (for instance 'normal' water column and compressed water column).
   If this is the case, you can select which one you want to view here.
   If you have selected a processing tool in the previous step, some options may be disabled as a specific data packet is required by that processing tool.
   It is not possible to record multiple packets of the same data type (e.g when both 'normal' water column and compressed water column data are supported by the unit, only one can be recorded).

4. Snippet sample window size
   It is strongly advised to use the auto setting (0), then the Sonar will intelligently determine the optimal number of samples, balancing image quality and size.

5. Synchronize recording with Qinsy
   If this checkbox is ticked, recording will be synchronized between Qinsy and the multibeam manufacturer's software.
   The file name of the S7k file will match the name of the database file used in Qinsy.

Qinsy is only able to communicate that recording should start/stop plus the desired name of the recording file.

Please make sure to manually set up all other recording parameters in the manufacturer's software (for example, which packets are included in the recording) prior to using this feature.

Not all systems supported by this driver may support this feature.

Norbit systems, for example, do not currently support external starting/stopping of recording.

• If these presets of settings do not suit your needs, there is a possibility to manually select which raw packets should be stored in the database.
  In order to do this, tick the 'Manually select recorded packets (advanced)' check box.
  The dialog will change to allow you to manually choose which packets are stored for bathymetry, water column and snippets:
  

  

  
  Only the record types supported by the chosen device will be available for selection.
  The following options may be available:

Please note that prior to Qinsy 9.3 the 7000 record was not stored when 7006/7004 was selected for raw bathymetry. This may lead to a confusing situation:

1. Where the data was recorded in Qinsy 9.2.3 or older:

   • The client has selected '7006/7004' for raw bathy storage (note that in the older versions it was named 7006/7004, not 7006/7004/7000 because we would not store the 7000 records)

   • The 7006 and 7004 records are stored in the database. The 7000 record is not.

2. And this is then brought into Qinsy 9.3.0 or newer:

   • If we open the recorded database in Database Setup the raw bathy storage will now read '7006/7004/7000' which suggests that the 7000 record should be in the database.

Takeaway: If you are ever in a situation where you're looking at client data that you believe should contain 7000 records but does not, verify that it was recorded in Qinsy 9.3.0 or newer.
If you're stuck, feel free to reach out to me (Bouke) directly.

Warning: Storing Water Column Imagery

Please note that because of the possible size of water column packets, an additional step is needed to actually store the raw packets in the database.
Selecting a water column package in Database Setup will make it available for online viewing, but to actually store the raw packets in the database you will need to change the following setting in the Controller when online:

Session Setup >> Storage >> Database >> 'Store MBE Water Column Imagery'

• 

Note: Roll/Pitch/Heave stabilization

Roll/Pitch/Heave stabilization options can not be set in Database Setup.

This is not necessary since the new 7027 Bathymetry message will report the actual steered beam angles (relative angles to the sonar Rx surface) to Qinsy.

Qinsy can correct these relative angles by applying the reported MRU attitude angles. This results in absolute beam angles.

1. Enter the location of the Multibeam on the object (Vessel / ROV / AUV):
   

   

Separate Transmit and Receiver transducer node offsets

For optimum calculation results we strongly advise to enter separate Transmit and Receiver transducer node offsets. This is also true for circular array transducers like the Seabat 7101 uses.
Refer to the operation manual for the details on the acoustic centers of the transducers.
The only case where it is not advisable to use separate Transmit and Receiver transducer node offsets is when the 7027 bathymetry datagram is not available or desired and the older datagrams (7004/7006) are used.
In this scenario, the driver should be set up to use a common acoustic center since the older datagrams report travel times and angles that are corrected by Reson for the separation between the transmitter and receiver.
The node location of the common acoustic center should be that of the reference point specified in the Reson Operator's manual.

2. Enter the 'Max. beams per ping' applicable for the system.
   Since Qinsy 9.2.0, 1024 beams are supported

3. On the next page, Echosounder Accuracy Parameters, you can enter the parameter used for the TPU calculation.
   The results of the TPU calculations are used for IHO filtering, CUBE, etc.

4. On the Next page, Multibeam Echosounder Corrections, you could select sensors that would be used for adjustable alignments of the multibeam installation.
   Some vessels can rotate the multibeam for quay wall / jetty / breakwater inspections.

5. When finishing the setup wizard you will be prompted by a dialog that will offer you the option to install other systems that use the same driver executable:

   

   When you click on OK, a new wizard will be started to set up the related Sidescan Sonar system.

Sidescan

Note

Please note that sidescan data is not available for Odom MB2 and Blueview systems.

If the backscatter data is to be visualized then:

1. If you cancelled the prompted additional driver wizard mentioned above you have two options:

   1. Right click with your mouse on the MBES system you have set up and select the related Sidescan Sonar driver:

      

      1. Driver type, Driver, Port number and IP are already selected for you and correspond with the related MBES driver

      2. In case you have a dual head system (i.e. SeaBat IDH T20/50-R) you need to:

         • Manually add a second Sidescan system to decode the sidescan data from the second head (see point b. below)

         • Select the associated Multibeam System (head) (see point 2 below).

   2. Manually add a Side Scan Sonar (SSS) system

      1. Select driver "Reson Seabat 7K (TCP/Network)",

      2. The port number should always be 7000, Enter the IP address of the Seabat 7K System. 

2. Select the same object as you have selected for the related MBES driver and select the associated MBES system:

   

3. Add a Port side and Starboard channel. (Read more about SSS systems in 'How-to Sidescan Sonar' in the Qinsy Knowledge Base).

   

   (Associated system: T50 Stbd)

Time Synchronization System

1. When Qinsy software is running on the same PC as the Reson 7K software (e.g. for 8125 Hybrid system) and the latter is synchronizing the MSWindows clock, it is possible to select a special Time Synchronization driver that will use only the Windows system time and not synchronize it.
   Select driver "Third party synchronized Windows system time".

2. When Qinsy is running on a separate PC then don't use the driver mentioned above, but use a Time Synchronization driver that does synchronize the PC clock.

   1. When all time critical systems are interfaced with Time Synchronization and Time message (ZDA / UTC / RMC) one does not need a QPS-TTL Time Synchronization adapter.

   2. The use of the QPS-TTL Time Synchronization adapter will make identifying timing errors easier.

Reson Remote IO (RRIO)

RRIO is a protocol used for distribution of raw data messages. The RRIO is used by the RESON SeaBat 7K, the RESON T-series and the Odom MB2 sonar system.
With the RRIO it is possible to receive the device data as interfaced to the RESON SeaBat or Odom MB2 RTA by Qinsy.
RRIO can be used as an alternative to the S7K driver for position, attitude and gyro.

There are a couple of drivers where there is the option to set another system which the data is acquired by.
For instance the NMEA Position and Heading driver shown below:

Interfacing Example

Bathymetry / Snippets / Water Column

1. Add a new "Multibeam Echosounder" system to the object in your template database

2. Select driver "Reson Seabat 7K (TCP/Network)" unless you use a Dual Head Norbit system.
   In that case use the same driver for both heads

   1. Port Head "Reson Seabat 7K (TCP/Network)" 

      1. Port 7000

   2. Starboard head "Reson Seabat 7K (TCP/Network)"

      1. Port 7001 (port+1)

3. The IP address should be the IP address of the Norbit system.

4. Used IP address should be the computer that is running the WBMS Software, leave at 127.0.0.1 if running on the same machine.

   

• On the Seabat 7k Settings page we can select which raw packets are stored in the database:
  

  

  1. System
     Select the system you are using with this driver. 

  2. Packet storage for processing
     Here you can select which processing tool (if any) you want to use. When a specific processing tool is selected, the raw packets required by that tool are automatically stored in the database. 
     Only the processing tools which are supported by the device you are using are shown.
     Supported processing tools include:

     • FMGT - FlederMaus Geocoder Toolbox 

     • FMMW - FlederMaus Mid Water

     • XTF - Processing tools that can handle eXchange Triton Format import (CARIS / PDS / ect.)

Tip

In the Knowledge Base you can find the document 'How-to Create XTF'.

Sound Velocity

It is advised to check the reported Sound Velocity (SV) by the MBES against the Sound Velocity Profile (SVP) used during acquisition.
The reported SV by the MBES cannot be altered afterwards or during Replay.
An alert can be set to compare the SV against the SVP:

Filtering

Online and Replay offer the user the possibility to filter the data for the Reson Brightness en Colinearity tests.
