SYSTEM SETUP

There are two ways to connect to the HydroSurveyor:

Standard Serial connection: Enter only the port number. The driver automatically determines the best baud rate, parity and stop bit.

Radio modem and UDP network connection: In this configuration, the GPS data comes through the base station. The SonTek HydroSurveyor driver then broadcasts the GPS data within Windows®, to the GPS driver.

The HydroSurveyor transmits the data to the SonTek HydroSurveyor driver via serial connection to a USB antenna on your survey computer.

SonTek HydroSurveyor driver parses the data and sends the GPS data to the GPS driver via the UDP port specified both in the SonTekM9.dll Driver Setup, and the GPS.dll connection settings.

HYPACK® HARDWARE CONFIGURATION

The simplest hardware configuration (Figure 1) includes only a GPS (GPS.dll) and the SonTek HydroSurveyor (SonTekM9.dll).

IMPORTANT: If you plan to use HydroSurveyor bottom tracking (DVL), the HydroSurveyor and the GPS should be assigned to separate mobiles.

SONTEK HYDROSURVEYOR

SONTEK HYDROSURVEYOR DEVICE SETUP

FIGURE 2. Configuring the SonTek HydroSurveyor in HYPACK®

Position: Required only for DVL positioning (bottom-tracking).

Depth: Logs sounding data.

Heading: Logs heading based on the change in position over time.

IMPORTANT: Log heading from only one device. If you are logging heading from your GPS, do not check this option for the M9 HS.

Heave: Logs pitch and roll data.

Generate Output Messages: Generates a SonTek YDFF file using the root name of the HYPACK® Raw file.

Record device specific messages: Required to calculate the sound velocity at the sensor depth based on salinity and temperature. This calculation is stored to an SVP record in the Raw data.

Use for matrix update: Do not select this function! To color the matrix with the HydroSurveyor, select the Use for Matrix Update option in the Driver Setup dialog.

SONTEK HYDROSURVEYOR DRIVER SETUP

FIGURE 3. SonTek M9 HydroSurveyor Driver Setup

Use as Multi-transducer records all 5 beams as multi-transducer records (*.ECM) in the Raw files. Deselected, the driver reports only the nadir beam to an EC1 record.

Use for matrix update: Color-codes a matrix based on the data received from the five active beams.

Salinity (ppt) is used to calculate the speed of sound. The driver logs SVP records to the Raw file.

Tip: The driver defaults to 0, which is appropriate for fresh water surveys. An appropriate default for seawater surveys is 35 ppt.

GPS Port: Required to connect the SonTek system with HYPACK®. This is the UDP Port from which your GPS driver reads the data. In this configuration, the GPS data comes through the base station. The SonTek M9 HS driver then broadcasts the GPS data within Windows®, to the GPS driver at this port.

NOTE: The GPS driver must be configured as a UDP Server on this

port. (You can leave the Write Port blank.)

SONTEK HYDROSURVEYOR CONNECTIONS

Standard Serial connection: Enter only the port number. The driver automatically determines the best baud rate, parity and stop bit.

FIGURE 4. Configuring a Serial Connection in HARDWARE

Tip: Use the COM Port Test from the Survey Connect tab to determine the correct port number.

Network Connection: Required to use the HydroSurveyor for bottom tracking (DVL). To connect the device to the HydroSurveyor with the radio modem, use the network mode with UDP port connection. The port address, by default, is 5656, but can be changed in the SonTek driver set-up.

FIGURE 5. Configuring a Network Connection in HARDWARE

GPS CONFIGURATION

Use the GPS.dll to read GPS data.

GPS DEVICE SETUP

Position (required)

Heading: If you have a dual antenna GPS, configure it to output a NMEA heading string (VTG) and check this option. Otherwise, leave this option unselected and configure the SonTek system to calculate heading in its Device Setup.

IMPORTANT: Log heading from only one device. If you are logging heading from your M9 HS, do not check this option for the GPS.

Tide: HYPACK® supports RTK tide corrections, with the correct project and driver configuration, and an RTK-capable GPS.

GPS DRIVER SETUP

To access the Driver Setup dialog, click [Setup] in the Device Setup dialog.

The most important part of the driver setup in the HydroSurveyor configuration is on the Advanced tab where you indicate the NMEA data strings the driver will read from the GPS. The typical output is GGA for position and VTG for heading.

FIGURE 6. GPS Driver Setup

GPS CONNECTION

To connect a stand-alone GPS, the connection can be via a standard serial port or network port.

To connect the device to the SonTek HydroSurveyor with the radio modem, use the network mode with UDP port connection. The port address, by default, is 5656, but can be changed in the SonTek HydroSurveyor Driver Setup.

FIGURE 7. GPS Network Connection Settings

THE HYDROSURVEYOR IN HYPACK® SURVEY

The SonTek M9 HS driver has a tabbed device window in SURVEY, each tab with different displays and purposes: Depth, Beam Profile, and bottom tracking.

DEPTH TAB

A chart with the last 100 depths. In addition, the window displays the uncorrected depths in the sensor head diagram. The graph can scale automatically, but you can also manually set the depth range. You may also modify the trace color for each beam.

To set vertical scale for the depth graph, use the Chart Scaling options.

1. Click [Chart Scaling] to access the configuration dialog.

FIGURE 8. Chart Scaling Dialog

2. Set your options and click [OK].

Autoscaling: Select the Auto Minimum/Maximum option.

The Minimum Distance option defines the smallest depth

range you want to display.

Manual Scaling: Select the Fixed Minimum/Maximum

option and enter the depth range you want to display.

The HydroSurveyor in HYPACK® SURVEY • Beam Profile Tab

FIGURE 9. SonTek M9 HS Device Window—Depths Tab

BEAM PROFILE TAB

The Beam Profile tab shows the current velocities (corrected for the bottom track velocity) and a beam amplitude profile along its path to the bottom. On the right, the circular display shows the velocity of the current relative to the boat. The optional amplitude  profile display is useful to QC check your depths. The beams should descend smoothly together until they reach the bottom.

To show the amplitude profile, check the Show Beam Amplitude option.

To choose the value for the graph displays, select from the drop-down menu options.

To customize the color settings, the Colors icon accesses the standard Colors dialog. The colors configured from the Profile window affect only the Profile display.

USING BOTTOM TRACKING FOR POSITIONING

You can use SonTek M9 HS bottom tracking for positioning in areas where you are likely to lose GPS signal.

Tip: When using bottom tracking, it is useful to assign the HydroSurveyor and GPS to separate mobiles. This enables you to compare the positioning of each system and prevents the vessel display in the HYPACK® SURVEY Map window from jumping as you change systems. During SURVEY, just before you lose GPS signal, check the Use Bottom Tracking check box in the Bottom Tracking tab of the Device window. When you regain GPS signal, clear the same check box.

IMPORTANT: We recommend using the bottom tracking only when you need it. Its position is relative to the last position allowing errors to propagate over extended periods of time.

The Device Window display in the Bottom Tracking tab shows the GPS position (blue) and the bottom tracking position (red).

Post-Survey Processing • Editing Your Data in the SINGLE BEAM EDITOR

FIGURE 11. SonTek M9 HS Device Window—Bottom Tracking Tab.

GPS Position (blue) and the Bottom Tracking Position (red)

POST-SURVEY PROCESSING

Use the SINGLE BEAM EDITOR to remove outliers, and apply additional corrections as necessary. After that, your postprocessing methods depend largely on your final product goals.

The following sections provide only brief descriptions. For the details of each procedure, please refer to the HYPACK® User Manual (available in the \Help folder of your HYPACK® install) or the HYPACK® Help system.

EDITING YOUR DATA IN THE SINGLE BEAM EDITOR

The SINGLE BEAM EDITOR recognizes you are loading SonTek HydroSurveyor data and asks for beam handling instructions:

FIGURE 12. SonTek Beam Handling Options

Vertical Beam Only: Reads only the nadir depths into the editor.

All Beams: This option ignores beams where depths are reported as zero, and presents each beam separately: the nadir named with the line name (eg. LineName.EDT), and each of the other 4 beams named LineName_BeamNumber.EDT” (eg. 001_0903_7.EDT).

Not Selecting SonTek M9: Enables you to process sounding data logged simultaneously with another echosounder. Select the alternate echosounder in the Read Parameters.

If you have used both GPS and HydroSurveyor bottom tracking, you must edit the data set twice—once for each positioning device:

1. Choose the Navigation device in the Selections tab of the Read Parameters dialog during the file loading process.

2. Remove outliers, and apply any additional corrections.

3. Save each data set separately, setting different extensions in the File Save options, then compare the results. The editor saves the resulting data, by default to the project \Edit folder, in edited ALL format files.

FINAL PRODUCTS

Once you have cleaned your data, the Final Products module you use next depends on your project output requirements.

TABLE 1. HYPACK® Modules for each Output Requirement

The following sections provide a very small preview of the nature of the output from each module. For full details on data processing,please refer to the HYPACK® User Manual or Help system. (Both may be found in the \Help folder in your HYPACK® install.)

ADCP PROFILE

Use the ADCP PROFILE program to view the current profiles in the YDFF file

To view the current profiles, use the ADCP PROFILE program:

To use the HydroSurveyor bottom tracking for positioning, load the YDFF files fromHYPACK® SURVEY.

To use positioning from the edited data, load the edited LOG files. In this case, ADCP PROFILE merges the positioning from the All format files with the YDFF ADCP data. Recalculating positions in the SINGLE BEAM EDITOR can improve your positioning.
