Thanks

I would like to begin by thanking the University of Baria Vung Tau (BVU) for

having welcomed me to their school and their campuses for this period of training, and

for giving me the keys to live in Vietnam.

I thank Mr Le Ngoc and Mr Le Viet, professors in electronics at the university,

for their availability and for the quality of the exchanges we had during this internship,

allowing me to enrich myself and to evolve professionally.

Introduction

The training of the professional license Marine Electronic Systems (SEME)

includes a training period of 490 hours.

In the training course of the SEME professional license, the internship is

necessary to discover several technological facets of marine electronics. It allows you

to acquire skills and know-how specific to each company.

I chose the internship in Vietnam at the University of BVU with the purpose of

the realization of a central navigation "low-cost" because it was mainly found an

internship in France and the opportunity presented through Mr Vo, that represented for

me a chance to discover a unique know-how and culture in the world.

I. Presentation of the project

The interest of this project

The interest of the project is to come and give navigational tools to Vietnamese

navigators. Indeed, on 300 000 Vietnamese boats, none have systems to navigate from

point A to point B, they can not follow any road where even to locate to access an area

they already knew, which could be very convenient for fishermen who want to find their

fishing zone.

They also have no weather systems and the price for a navigation system is very

elevated compared to the average budgets of the Vietnamese.

Our solution

2017-2018

To avoid this problem, we will create a central navigation low-cost by connecting

to a Raspberry PI card, an LCD display, a radio module and a GPS mouse for displaying

and information of satellite data, and then for installing a system operating system and

navigation software to allow Vietnamese navigators to navigate serenely on the waters.

As there are no nautical charts for Vietnamese waters, free and downloadable on

the Internet, we will have to create a map of the east coast of Vietnam with the software

" Opencpn ", " GE2KAP " and " Google Earth " which will allow to use image overlay

skills to capture, calibrate and use it by the navigation software.

Opencpn

OpenCPN (open Chart Plotter Navigator) is a free navigation software. It can be

used to edit maps, to plan a route and to view its position in real time, if it is associated

with a GPS.

OpenCPN uses the GPS to determine the position of the boat and the data from

an AIS to trace the positions of the boats in the vicinity.

GE2KAP

Paul Higgins and his trusty sidekick Whitey authored the program GE2KAP.

This free software allows you to make charts with Google Earth overlays. The result is

an amazing combination of photo-real land detail and waterways that are navigation

charts.

IV. The realization

Creating the map

There are 3 ways to create a map of the coasts of Vietnam with the software

OPENCPN, GE2KAP and Google Earth.

First of all, it is necessary to install the software in Windows 10.

1°) Using the Google Earth Add-in (Plug-in) from OpenCPN

I loaded and installed the plugin « GoogleEarth » and followed the following

steps :

1) Run OpenCPN and choose a map.

2) Start the Google Earth plug-in by clicking on the ad-hoc icon in the OpenCPN

icons bar.

3) Display, in the GE plug-in, the area you want to transform into a map.

4) Start GE2KAP and wait for it to automatically connect to OpenCPN.

5) Enter a path and a map name in the field "path in PCNom: ".

6) Click the "Create Map " button in GE2KAP.

7) To view the resulting map, click on "See " in GE2KAP.

2°) Merge the Google Earth screen with that of OpenCPN

I loaded and installed the plugin « ge2kap » and followed the following steps :

1) Start GE2KAP.

2) Enter a path and a map name in the field "path in PCNom: ".

3) You can just specify the path that leads to the folder that will contain the map. In

this case, the created map will be named "OPENCPN. KAP "

4) Open, if necessary, the central part of the GE2KAP options

5) In the field "path in the PC to a map/image or OpenCPN screen", use the drop-

down list to enter just: "OpenCPN " (Do not enter a path).

6) Do not check the "create a non-merge KAP" checkbox. Do not use GE ".

7) Click the "Create Map " button.

3°) Calibrating a JPEG image

This method consists of capturing an image on Openstreetmap and then coming

to calibrate it with GE2KAP to be readable by OPENCPN.

I followed the following method :

1) Open Openstreetmap World

2) Choose a piece of card

3) Place the cursor in the left corner at the top and note the latitude and the longitude,

same thing for the right corner at the bottom.

4) Capture exactly the window rectangle, save and give a name to the JPEG file. (eg

VietNam. jpg)

5) Open the template. gpx file with Notepad. Type the latitude and longitude in both

lines.

GPX File

6) Save and give the same name as the image (eg VietNam.jpx).

7) Place the .jpg image of the card and the .jpx file in the KAP folder and start

GE2KAP by double-clicking.

8) In the window that opens . Press the button (1) >> and in the window, navigate

to open the folder and type in the 'File name' box the name that will be given to

the card (for example. VietNam.kap), Save , and close the window. The path and

name appear in (2).

9) With the button (3) >>, navigate to search the KAP folder of GE2KAP, and click

on the image (for example VietNam.jpg), open, close the window. The path and

the name are displayed in (4). Type Meters in (5). Mark the box (6) and click on

'Create KAP' (7).

10) When the window announces 'Successfully created ...', open OpenCpn, in the

Toolbox / Maps, 'add directory' which contains the new map.

2017-2018

After having tested these 3 solutions, none of them worked, most of the time,

the card does not register in .kap format readable by Opencpn or so I had this error code.

Error: GE KML Copy Failed!

Error: Can not find on Google Earth the image overlay edit window.

Error: Unable to add the merge file:

C: \ DUMMY \ OPENCPN_DMY.KAP

Being blocked with these 3 solutions, I found a much simpler solution on

openseamap which offers free .kap maps for most of the world's maritime zones.

4°) Download free map on Openseamap

You have to open Openseamap and go to "download the map", then you have to

unzip the file and send it to a folder.kap that Opencpn knows.

Then in Opencpn, open the toolbox and go to "cards / data" then add the

folder.kap where is the file unzip.

Here is the result :

Remote control of the Raspberry pi

I decided to control the Raspberry pi with my laptop using the software "puTTY"

and "VncViewer". This choice is optional and is not necessary, but it is useful because

it avoids using too much material, like the mouse and the keyboard.

For this, simply go to the terminal of the raspberry and type "ipconfig" to find

the IP address. Then, you must install the software on your computer and establish the

connection by activating the SSH link on the raspberry and then physically connecting

it via an ethernet cable on the laptop.

When all this is done, open VncViewer and establish a new connection. When

you have typed the IP address of the raspberry who is “169.254.14.132”, it's over.

I can finally control the screen of my raspberry with my laptop.

Installation the GPS mouse

To install the GPS mouse, just install the driver and then connect it to the rasp-

berry. Then, you have to configure the connection in Opencpn, in the menu options >>

menu connections.

Just click on "add connection", choose the "serial" mode, select the com port

and choose the connection speed which is "4800 baud". Cheksum control is optional.

To check if the connection is established, check "open the NMEA data display

window". NMEA data appears which confirms that the connection is established.

We also have the position of the GPS which is automatically displayed in

Opencpn.

Installation the module NEO-6M

Installation of the NEO-6M module is completely optional. It all depends on the

technical solution you want to choose. The module works like the GPS mouse but it is

cheaper.

We connect it to the GPIO pins of the raspberry to test it but if we really wanted

to implement it, it would have been necessary to convert the signal to USB with a cable

TTL REV 232 3V3 to configure it with the Opencpn software.

Three possible technical solutions with price estimation

Not knowing how the boat is equipped for system installation. I propose to

make a cost estimate for 3 possible technical solutions.

1) If the boat has 220 volts AC 50 Hz.

2) If the boat has not 220 volts AC 50 Hz.

3) By replacing the GPS mouse with the NEO-6M.
