CHAPTER 1 Using DelphNav™ (Survey Control Panel) DelphNav Overview (Survey Control Panel) DelphNav, embodied collectively in DelphMap™ as the Survey Control Panel, is a fully functional navigation package. It can receive and display up to two different sources of positioning information (for example, GPS, RTK, ATS, USBL, User-Defined) in addition to data from single-beam echo sounders, multibeam echo sounders, motion sensors, and auxiliary sensors (for example, gyros, depth sensors).
DelphNav Overview (Survey Control Panel) Using Delph Nav To run DelphNav 1. Start DelphMap (Delphmap.exe) and select the Survey Control Panel option from the View menu (View → Survey Control Panel; Figure 1). 2. Click Project → New Project or Project → Open a Project. 3. Select the folder you want to work in and the name of your project. Your DelphMap project file either opens if it already exists, or is created if new. You are now ready to set up your serial ports and survey lines.
Using Delph Nav Setting Up Serial Ports Setting Up Serial Ports Serial ports are set up in DelphNav to track and log navigation data along with any other relevant ancillary sensor information (e.g., gyros, depth sensors, velocity sensors, etc.). Ports may also be allocated for the output of ASCII strings derived from incoming data. Message templates can be assigned to ports to clarify which information strings hold higher precedence (e.g.
Setting Up Serial Ports • Shape Using Delph Nav This relates to the object shape to be displayed in DelphMap for the particular navigation type. If two navigation strings are being received (e.g., vessel position and towfish position, or GPS position and Automatic Tracking System (ATS) position), a different shape can be allocated to each navigation type. • Settings / User DefinedOptions specific to the Output and User Defined Input system types.
Using Delph Nav Setting Up Serial Ports 3. Specify any additional options to be applied to the incoming string in the lower righthand panel of the settings dialog box. For example, in the case of navigation from two different sources arriving on two different COM ports, designate which navigation system should be used as the Primary source by typing the command MASTER into the options text box. By default the lowest numbered serial port is assumed to contain the Primary navigation.
Setting Up Serial Ports Using Delph Nav • Information output from DelphNav relates to the navigation string declared as Master. • Data Display and Compass windows may be opened for either or both navigation input strings, with the Master string denoted by an “M” in the window menu bar (an “S” denotes the Secondary or Slave string). A more complete description of available message templates and associated options is provided in the Message Templates and Options section of this manual. 4.
Using Delph Nav Serial Server Serial Server In order to keep the input and output requests from different applications from clashing when they access data from the same COM port, TEI has developed a Serial Port Server program, called SERIALSRV.EXE, to manage the process. Currently Delph Seismic, DelphSeismicPlus, and DelphNav use this program when reading data from a serial port in real time. The server program launches automatically upon selecting the Serial Port Linkup button.
Serial Server Using Delph Nav 3 GUI on top GUI minimized FIGURE 4. Serial Server Settings dialog for selecting COM ports An error message will be generated if the port is already busy through another application or if that port is not present on the particular system in use. Click OK when the parameters have been set correctly to return to the Serial Server dialog box.
Using Delph Nav Serial Server FIGURE 5. Serial Server GUI minimized as icon in system tray If the GUI is minimized in the System Tray (Figure 5), left-clicking the icon restores the serial server dialog box. Right-clicking the icon enables you to make changes to the serial setup without restoring the full dialog box. Special Considerations for Working with Serial Server As of the Fall 2000 release of TEI software, SERIALSRV.
Serial Server Using Delph Nav 1. Shut down Serial Server if it is running: Click the serial server icon in the system tray next to the system clock, and then click the X in the top right corner of the Serial Server Settings box to close it. 2. Use Explorer to find and delete the two INI files SERIALSRV.INI and SERIALDLL.INI. 3. Check that the only copies of the following files are those that are in the C:\{Windows Folder}\TEIdlls folder: • SERIALSRV.EXE • SERIALDLL.DLL • MPX_LLNE.DLL • TEIGUIEXT.
Using Delph Nav Message Templates and Options Message Templates and Options A number of pre-defined message templates exist for parsing information arriving at a serial port from a particular system/sensor. Those templates are shown in Table 1. TABLE 1. Input Systems and Supported Message Formats System Navigation Single Beam 2004.06.

Making or Using a Survey Plan Using Delph Nav Making or Using a Survey Plan A Survey Plan is essentially a set of lines over which the survey will be run. The Survey Planning Editor enables you to do the following tasks: • • • • • • Draw lines along which the vessel can be navigated. Draw points as individual waypoints towards which the vessel can steer. Create an object or lines manually by typing coordinates into a spreadsheet. Import objects or lines from an ASCII file.
Using Delph Nav Making or Using a Survey Plan FIGURE 6. Survey planning dialog (before a project is opened) If no other imagery exists in the DelphMap window, DelphNav prompts you to choose a projection for your project when you click Done. These Projection and Datum parameters represent what will be displayed in DelphMap, and need not be identical to the Projection and Datum of the incoming navigation.
Making or Using a Survey Plan Note: Using Delph Nav To change the folder where your survey planning and other DelphMap / DelphNav-related files are saved, choose Project → Save As… and choose a folder. This folder then becomes the default folder for the whole project. Once a proper DelphMap project file has been opened or created, DelphNav displays the Survey Planning Tools dialog box (Figure 7). FIGURE 7.
Using Delph Nav Making or Using a Survey Plan To draw lines for a survey plan 1. From Survey planning setup click the Draw lines button (icon shown to the right), then use the title bar to drag the dialog box to one side. ( 2. Use the coordinate display in the Distance Window to position the mouse cursor at the start of the first survey line.

Click Add to add the pair of Northing and Easting values spreadsheet. To delete a waypoint, select the Northing/Easting couplet from the spreadsheet list and click on Remove. 3. Continue to specify new Northings and Eastings and Add them to the list until you have as many paired points as you want.
Making or Using a Survey Plan Using Delph Nav If you chose Profile(s), the system joins the paired points in your imagery with line segments. The “object” is registered as a line in the Survey Control Panel (select the Lines tab). manually created object FIGURE 11. Example of a manually created object in imagery Importing Objects From an ASCII File In DelphNav you can import a survey plan or set of lines in ASCII format.
Using Delph Nav Making or Using a Survey Plan Any line of text in your ASCII file that contains a non-numeric character is interpreted as a separator of data, not data itself. Separators and data exist on their own lines of text. The separator can be any string of text that’s meaningful to you. Separator lines should not be consecutive; real data (one or more pairs of navigation coordinates on one or more lines) must be the next line after a separator line.
Making or Using a Survey Plan Using Delph Nav Importing Coordinates in Latitude and Longitude When importing coordinates in Lat/Long format, the following formats are supported: • Decimal Degrees, DD.DDDDDD (e.g., 57.234567, 03.005678) • Degrees Decimal Minutes, DD.MMDDD (e.g., 57.14074, 03.003407) • Degrees Minutes Seconds, DDMMSS.SS (e.g., 571404.44, 030020.44) Note: No spaces are allowed. Positive longitudes are east, negative are west. Positive latitudes are north, negative are south.
Using Delph Nav Making or Using a Survey Plan FIGURE 13. ASCII file importation setup dialog box 3. Click OK. The next dialog box to open, the Input Projection Settings, allows you to specify the Projection and Datum of the coordinates to be imported (e.g., UTM, Zone 19, WGS84). Note that in the example provided in Figure 13, two lines of non-numeric characters occur between lines of waypoint coordinates (EOL and then SOL).
Making or Using a Survey Plan Using Delph Nav 5. If you are finished with planning your survey, click Done to close the Survey Planning setup dialog box. Figure 14 shows the outline of a quay imported from a DXF file with five survey lines; these lines are also listed in the Survey Control Panel window. Clicking the + sign reveals the coordinates for each line. FIGURE 14. Five survey lines imported from an ASCII file 26 CHAPTER 1: Using DelphNav™ (Survey Control Panel) 2004.06.
Using Delph Nav Making or Using a Survey Plan Creating a Channel The purpose behind creating a channel is to provide a reference surface to which a DTM of the seafloor can be compared. This tool also sets up survey lines along which the vessel can be navigated to acquire profile data across the designed channel. A channel-design file contains two basic sets of line objects: length-wise borders (one for each “side” of the channel) and a series of transverse lines (cross sections).
Making or Using a Survey Plan Using Delph Nav FIGURE 15. Channel design procedure dialog box 2. For the border currently being defined, click one of the three available buttons: Draw lines (left icon), Waypoint profile editor (middle icon), or the Open icon (right icon). • If you chose Draw lines, you can proceed to draw lines as previously explained in ‘Drawing Lines Independently of Each Other’ starting on page 16.
Using Delph Nav Making or Using a Survey Plan 4. In the available text boxes of the dialog box, either specify a value for the Distance between the cross sections or the Number of cross sections to create; click Finish. The system displays the current state of the channel design (Figure 65) and opens a Channel bathymetry dialog box (Figure 66). You use this dialog box to specify the slope of your channel walls and the depth/slope of the channel as a whole. FIGURE 16.
Making or Using a Survey Plan Using Delph Nav Within this window four points define each cross line: two points for the top of the channel at each border intersection (Points A and D), and two points for the bottom of the channel on each side of the wall (Points B and C). Depth values may be entered for all of these points, thereby setting the depth of the channel surface beneath sea level and the height of the channel walls.
Using Delph Nav Making or Using a Survey Plan FIGURE 17. Cross line profile before channel definition 2004.06.
Making or Using a Survey Plan Using Delph Nav 5. Progressively modify the Depth and X-Offset parameters associated with each of the cross lines (each of the tab fields) until the channel shape has been adequately defined. 6. Click OK when completed. Note: After defining the profile shape for one cross line, the parameters can be automatically passed to the next profile (or to the previous profile) through selection of the “Like previous” and “Like next one” buttons.

Making or Using a Survey Plan Using Delph Nav Modifying Line Properties As stated at the beginning of this section, by default the vector layer inserted into DelphNav and related to a survey plan is labeled SurveyPlanning. Properties related to each vector component of the specified survey plan (lines and waypoints) can be modified by right-clicking on the SurveyPlanning layer and selecting Properties. FIGURE 19.
Using Delph Nav Conducting a Survey Conducting a Survey Upon completing a survey plan, and assuming all sonar and navigation equipment are working properly, you should now be ready to commence surveying.
Conducting a Survey Using Delph Nav After a short time the Serial Port Linkup button will turn Green and the Serial Setup button will become grayed-out (inactive). At this stage a symbol representing the boat position should appear in the main DelphNav window. The shape of that symbol will depend on the Shape selected during Serial Port Setup.

Using Delph Nav Conducting a Survey Line Selection and Use of the Helmsman Display When creating a Survey Plan (for example, first creating a line and then creating duplicates of that line), DelphNav adds line names to the Survey Control Panel window (Figure 22). A number of options exist for manipulating these lines, including selecting a line to navigate relative to the Helmsman Display, reordering lines within the list, reversing the run orientation, and deleting lines. 2004.06.
Conducting a Survey Using Delph Nav FIGURE 22. Line navigation options in DelphNav Steering a vessel along a predetermined line is a basic necessity of practically any survey and a core function of any navigation package. In DelphNav, the Helmsman Display window (Figure 23) is a key tool for navigating a vessel along a line.
Using Delph Nav Conducting a Survey FIGURE 23. Helmsman Display The first step is to select the line along which you want to steer the vessel. In the Survey Control Panel, an elongated box marks the line that has been selected as the navigation line (Line 1 in Figure 22). If you wish to navigate along another line, simply select the new line either by: • left-clicking on a line object in the main DelphNav window, or • left-clicking on a line name in Survey Control Panel.
Conducting a Survey Using Delph Nav icons swap ends within the main DelphNav window. In addition, the box around the line name in the Survey Control Panel changes from “red” to “green” and the text associated with the “Way” field changes from Reverse to Normal. Line ordering becomes important if the Automatic Logging option is selected. This option is a part of the Settings dialog box, which can be launched from the lowermost button on the Survey Control Panel (Figure 22 on page 40).
Using Delph Nav Conducting a Survey Active Waypoint NCTS CTW CTS FIGURE 24. Course information within Helmsman Display Values associated with these parameters can assist in the navigation of the vessel. For example, the CTW parameter indicates the course the helmsman should steer in order to intersect the next waypoint (or end of line segment). The NCTS parameter informs the helmsman of the next heading that must be attained in the case of a multi-segment line.
Conducting a Survey Using Delph Nav The data are recorded in an XTF file separate from the sonar XTF file. The location of this navigation XTF file is the directory under which the DelphNav project has been saved, or by default in: C:\Documents and Settings\USERNAME\Local Settings\Temp (in the case of a New Project). The naming convention for these files is: ProjectName_LineName_YYMMDD_HHMMSS.XTF (that is, PortlandProject_L1_001204_092958.
Using Delph Nav Conducting a Survey FIGURE 25. Navigation Logging Options in Survey Control Panel If a single navigation XTF file is desired, then the operator may Pause Recording between lines (Figure 25). If a navigation file per line is desired, then the operator should Stop 2004.06.
Conducting a Survey Using Delph Nav Recording at the EOL, and Start Recording at the beginning of the next line (after selecting the new line to navigate on the Survey Planning toolbar). Automatic recording mode is activated through the Settings button at the bottom of the Survey Control Panel (Figure 25). The Settings dialog box contains parameters to Start/ Stop logging a specified distance from the SOL and EOL, and to Pause logging a specified distance off-line.
Using Delph Nav Note: Data Display Windows The color of the vessel track should indicate the status of recording (red for no recording, blue for recording). All navigation files may be played back in DelphNav through selecting the Files tab option of the Survey Planning window, opening the relevant XTF files, and selecting the Play button. Options affecting the playback of such files appear in the Settings dialog box shown in Figure 26 on page 46.
Data Display Windows Using Delph Nav FIGURE 27. Single Beam Profile window with alarm Minimum and Maximum depths for the Y-axis on the profile display can be set with the up/down buttons on the left side of the window, and the time-scale over which the profile is built (the X-axis) can be adjusted by the slider bar beneath the profile display. The display of either beam can be toggled ON or OFF by the Show option on the right side of the window.
Using Delph Nav Data Display Windows These options open the panels shown below the main profile window in Figure 27.
An Example of Survey Planning in DelphNav Using Delph Nav Helmsman Display This shows position of vessel relative to the operator-specified survey line. Parameters monitored include distance from SOL/EOL, off-line distance, course to next waypoint, and navigation data recording status. Data Display This provides a text overview of the incoming data strings. Raw values, statistics, and quality parameters may be viewed for navigation, attitude, and single beam data.
Using Delph Nav An Example of Survey Planning in DelphNav The data in this sample exercise is as follows: • a DXF coastline file from Portland Maine (portland.dxf), which has metric coordinate information based on the UTM projection and the NAD27 datum • a number of lines in an ASCII file based on UTM projection and the WGS1984 datum (portland_lines.
An Example of Survey Planning in DelphNav Using Delph Nav FIGURE 29. Open dialog box for importing a DXF file 2. When you select the file and click Open, a message appears (Figure 30): FIGURE 30. Message before importing a DXF file Because DXF files contain no projection information and because we do not yet have a project open, we will need to supply this information. 52 CHAPTER 1: Using DelphNav™ (Survey Control Panel) 2004.06.
Using Delph Nav An Example of Survey Planning in DelphNav 3. Respond to the message by clicking OK in the message box. The resulting dialog box asks you for the location where you want to store the imported file. Internally DelphNav converts a DXF file into three files having these extensions: DDS_VOB, DDS_VTX and DDS_VLB 4. Browse to a suitable folder and click OK. The system displays the Projection Settings dialog box shown in Figure 31.
An Example of Survey Planning in DelphNav Using Delph Nav 6. Because this DXF file in our worked example is the coastline around Portland, Maine, and because the coastline’s coordinates are UTM with NAD27 datum, select Universal Transverse Mercator; then click Next. At this point you need some idea of where Portland, Maine, is in terms of its navigation coordinates. It turns out the longitude of Portland, Maine, is around 70 degrees West, and it is in the Northern Hemisphere. 7.
Using Delph Nav An Example of Survey Planning in DelphNav Now we need to setup the output (or working) projection for the project. Recall that we want to use a GPS receiver having a data output in Lat/Long based on WGS84, and that the project is required to be in the UTM projection. 8. In the Projection Settings dialog box, click Change next to Output Projection; select Universal Transverse Mercator from the list, and click Next. 9.
An Example of Survey Planning in DelphNav Using Delph Nav FIGURE 33. Projection Settings box with output projection info 12.Click OK after checking that everything is correctly entered. If you wish, you can click Test to get a dialog box like the one shown in Figure 34. 56 CHAPTER 1: Using DelphNav™ (Survey Control Panel) 2004.06.
Using Delph Nav An Example of Survey Planning in DelphNav FIGURE 34. Test Projection Settings dialog box You can use this test feature to check whether the conversion from Lat/Long to grid coordinates in either datum is being carried out correctly, or whether to make “spot” conversions from Lat/Long to grid coordinates. For the former test, of course, you will need to have a test conversion carried out by some independent means for comparison. 2004.06.
An Example of Survey Planning in DelphNav Using Delph Nav 13.In the Projection Settings dialog box, click OK (either with or without doing Test). After a few seconds of processing, DelphNav converts the DXF file, at which time the following dialog box appears: FIGURE 35. Layer-insertion dialog box prompting By default the layer name will be the same as the DXF file name. In Figure 35 we have changed portland to portland_coast.

The system closes the Settings dialog box, and the imagery displays in your newly chosen colors. Figure 40 shows an example of this. 62 CHAPTER 1: Using DelphNav™ (Survey Control Panel) 2004.06.
Using Delph Nav An Example of Survey Planning in DelphNav FIGURE 40. Imagery displayed in a new color 18.At this point it is a good idea to save your project: Click Project → Save (or click the Save icon on the taskbar). This will not only create a DMP (DelphMap Project) file containing all the references to the various files that you have created, but saving the project also establishes the default directory for creating subsequent layers and converted files. 2004.06.
An Example of Survey Planning in DelphNav Note: Using Delph Nav DMP files do not contain the actual data files, just the links to the files used to display your imagery. Consequently, if you move this project from its present location/folder you will need to re-import the various files again, thereby updating the project’s links to the files. This completes the importation of the DXF coastline file.
