1.4 SDE-19 installation
Classical fix the transducer beside the boat
The position of the fixed transducer is best selected next to the middle side of the hull, avoiding the noise interference of the hull as far as possible, and then fixing it by pulling the rope at the front, rear, and bottom.
Notice
During the whole depth measurement, the transducer rod shall be kept vertical at all times. When you find the rod is not vertical, you need to check the data. So, it is important to fix the rod before you go to the survey.
SDE-19 Web UI
2.1 WIFI connection and log in to the web UI.
- Search the WIFI hot spot, the hot spot name is “SOUTH_”+” the last 4 digital SN of SDE-19”. Take “S26104A0000022” as the SDE-19 SN as an example, we can search the WIFI hot spot is ”SOUTH_0022”. Click to connect with this hot spot without a password requirement.
- After connecting with the hot spot, then run the browser and input IP ”10.1.1.1” to log in the web UI as below picture
- Type the username and password both “admin”, then click login to see the web UI configuration as below picture:
Web UI introduction
Quick guide for SDE-19 with Seastar software
Seastar connects with SDE-19 and GNSS receivers.
Install and power on SDE-19, also prepare the GNSS receiver and power on.
A. Run the Seastar software in N80 and search the GNSS receiver bluetooth
in the “settings – BT manages”, then click “search” to search the receiver SN,
then select the SN and click connect, see as below pictures:
B. Enable the N80 WIFI and connect with the echo sounder WIFI hot spot, then back to Seastar and click “Setting – Sounder – South Sounder ”, turn on the “Sounder network connect” , see as below pictures:
C. Input the value of sound speed(velocity) and draught. The sound velocity depends on the water environment, normally we can use a sound velocity sensor to get the value of sound velocity, or we can use bar check to calculate the sound velocity, even sometimes, we manually edit the velocity to match the depth which echo sounder display with the real depth.
The draught is the depth of the transducer. Normally we put the transducer into water at 0.5 meters depth, and our survey pole also has a red mark to show 0.5m line.
About the measurement gear, it is the maximum depth value. It is very important for auto-adjust parameter survey mode(“measure mode – Auto” in “High-frequency setting”). So if you already know in this area, it will not be deeper than a value, please select the pear as in below picture, if you don’t know the value, select the “Auto”
D. Select the measure state “On”, then select the measure mode “Auto”, then click “Send”, see as below screenshot. If configure done, you can see a feedback message “Sounder parameters sent successfully”, then we can back to the main interface of Seastar.
Create a new project, and input the coordinate system parameters and localization.
A. Click “project – New project”, then input the project name, then click “OK”, then we can click the “coordinate system”, then click “new system”, then type a coordinate system name in the “coordinate system”, then select and input your local coordinate system parameters. Then click “OK” and apply to current project.
- B. Localization:
- B -1. UHF RTK mode.
- B -1-1. Set base at no point. After connecting with the base station, then click “setting – instrument setting – Base setting” Then input the base parameters and base coordinates as below pictures:
-
Normally, we use RTCM32 as message format and emission frequency as 1 second. Then we can select the “Base position” as the Manual start base, and input the coordinate.
-
We also need to input the antenna height and select the data link(Internal radio or external radio), for internal radio we can select the radio data source to configure the radio parameters.
-
After setting the above, we can click “start base”, if the GNSS satellite PDOP is less than 3.5, the base will start transmitting correction data via UHF radio.
-
B-1-2. Then we can use Seastar to connect with the rover, and set the same radio parameters to get fixed.
-
B -2. CORS mode. If connect with CORS, we don’t need to do the localization step.
-
B -2-1. We need insert the SIM card in the GNSS receiver(we need configure the APN information in the GNSS receiver) and then set GNSS receiver as “Internal GSM” mode, then click into the CORS setting
B-2- 2. Then we can add the CORS network parameters as in below pictures: “Add” and input the CORS connection name, then input the CORS parameters, set the APN, then click “Mount point” and click “Refresh access point”, then select the correct access point, and click OK. Then you can select your CORS connection just added, and click “connect”. If all connect successfully, it will show a tick with “logon server”
Sea survey/hydrographic survey/bathymetry.
After we finish the device connection, device parameters setting and coordinate system setting. Then we can start the hydrographic survey.
Click into the hydrographic survey function, and click “survey – sea survey”.
Click “Option” into the collection setting(Mark set.), then select the mark mode(by distance or by time)
Select the Wiring form as “zone wiring”, then click “OK”, then you can click the screen to add the points as the boundary of the survey area, then click the “complete” icon. You will see the “wiring setting” parameters interface, then input the Tilt angle and line spacing, and click “OK”, then you can see the plan lines in the survey area. See as below pictures:
Auto survey function(by time or by distance). Click “Manual and Auto” to
switch the collecting mode(the icon shows “Auto” means now it is auto survey
mode). Then click
“Measure” and input the point name and antenna height, and then Seastar will
collect points automatically. We can click “View” to check the data.
Data export. Back to the main interface of Seastar click “Project – Import/Export – WaterDepthFile”, then input the exported file name and file type(data format), then click “OK”. After exporting successfully, we can copy out the .dat file and open it as a CSV file(rename the extension “.dat” as “.CSV” ).
