Navigatrix comes pre-configured with a comprehensive set of applications
for almost anything one could want to do on a boat with a computer:
navigation, communication, word processing and spread-sheeting, photos
and graphics, sound and video, ... - you name it. This section provides
an overview of the applications that can be found under the “Manta Menu”
in the bottom left of the Navigatrix desktop.
Where available, the text below will provide a link to the applications
online documentation and/or project website for further information.
- Archiver: Compress and decompress data with Xarchiver. Offline help
under /usr/share/doc/xarchiver/html/index.html (will be opened in
Firefox when selecting “Contents” from the help menu.) URL:
- CD/DVD Burner: Burn CDs and DVDs with Xfburn. URL:
- Disk Encrypter: Disk Encryption with TrueCrypt. An excellent
cross-platform utility to store encrypted files on a physical or
virtual disk. Good PDF user guide available locally by selecting
“User’s Guide” from the Help menu. The Help menu also contains
web-links to a beginner’s tutorial, FAQs and online documentation.
There is a thread on the Navigatrix Support Discussion
Board on how to
create a fully encrypted bootable USB stick with Navigatrix. URL:
- File Copier: Manage files with two panels side by side using Double
Commander. Handy utility for copying and moving files around the file
system. Also good for renaming multiple files in one go without
command line acrobatics, comparing the contents of directories and
many other basic tasks. URL:
- File Manager: Browse the file system and manage the files with
PCManFM. Similar to the Windows file manager. Default configuration
will delete files permanently after confirming (no trash bin). You
can change this in the File Manager’s menu under Edit -> Preferences
by checking “Move deleted files to trash bin”. To toggle displaying
hidden files on/off you can use the keyboard shortcut: [ctrl]+[H].
Under Unix, hidden files start with a “.” and are primarily used for
configuration files and internal housekeeping. Usually you don’t want
to see them to avoid clutter but sometimes you’ll need to get to one.
- Password Storage: Store your password safely with KeePassX. This is
the Unix version of the KeePass password manager that is available
for Windows. The Unix version supports automated login into
applications and websites. See the “User Guide” available offline
under the application’s help menu. URL:
- PGP Encryption Keys: Manage your PGP encryption keys with Seahorse.
- System Profiler and Benchmark: Only developer documentation available
online. Application should be self-explanatory though. URL:
- Terminal Emulator: Use the command line with LXTerminal. Can also be
invoked anytime by pressing [ctrl]+[alt]+[T] key simultaneously. From
the File Manager’s Tool menu you can also open a terminal window in
the File Manager’s current directory (in File Manager: Tools -> Open
current folder in terminal - pressing [F4] in File Manager does the
same). URL: lxde.org
- Virtual Keyboard: Use your mouse as a keyboard with onboard.
- World Clock: See the time in other timezones with gworldclock.
- Go: Play the oldest board game of the world with qGo. Extensive
offline documentation for this game can be accessed locally on your
- Mahjongg: Disassemble a pile of tiles by removing matching pairs.
- Sudoku: Test your logic skills in this number grid puzzle.
- Chart Converter: Convert images to kap charts and calibrate them. The
menu entry invokes the shell script makekap under /usr/local/bin.
This script first asks for an image file to be calibrated, converts
it to chart.jpg under /home/<user>/Desktop and then launches the
Windows program SeaClear for the user to perform the geo-referencing.
The user then saves the calibration (as
/home/<user>/Desktop/CHARTCAL.DIR). Upon the user exiting SeaClear
the script calls the tif2bsb utility to create a \*.kap chart file
from the original image plus the calibration data. The chart can be
loaded into OpenCPN. Sounds complicated but it is in fact pretty
straight forward and the makekap script displays messages and
instructions along the way. There is also a helpful
entry on the
Navigatrix Support Discussion Board.
- Image Manipulator: Create images and edit photographs with Gimp.
Powerful open source image editing at the same level as PhotoShop.
Extensive offline documentation available under the application’s
Help-menu. URL: www.gimp.org
- Painting Program: Create pixel art and manipulate digital photos with
- Photo Manager: Organize your photos with Shotwell. This is a photo
library similar to Picasa with some basic image touch-up functions as
EMail Client: EMail client Sylpheed. Fast and light-weight email
client. Documentation is available offline under the Help-menu.

/usr/local/bin/satphone which calls another script (comports in same
directory) to link usb2serial ports and then calls the wvdial PPP
Skype: Internet Telephony with Skype.
Tor Proxy: Browse Anonymously over the Tor Network with Vidalia. This
is a tool to bypass restrictions on wifi (or cable) networks that
block critical information and block downloads based on filename
extensions. You start Vidalia (Manta Menu -> Internet -> Tor Proxy)
and wait until the window that pops up shows that you are connected
to the Tor network.
Then, in the Firefox web browser, click on the little onion with the
red “X” in the upper right (next to the search box) and select
“Toggle Tor Status” which should make the little onion turn green.
Just remember with great power comes great responsibility... URL:
Torrent Client: Download and share files over BitTorrent with
Web Browser: Browse the World Wide Web with Firefox. Navigatrix has
Firefox pre-configured with some useful add-ons (in addition to the Tor
“anonymous browsing” utility mentioned above). One is ScrapBook, a utility
that lets you download webpages, and store and organize them in a library for
later offline reading. Scrapbook also allows to make annotations to
downloaded pages. It can be accessed under the ScrapBook menu in Firefox. You
can display a list of your downloaded pages by pressing [alt]+[K] in Firefox.
The other helpful add-on is “DownThemAll!”, a download manager that - amongst
other things - allows you to download multiple links from a webpage.
DownThemAll! is available in the context menu in Firefox whenever you
right-click on a link. It can be configured under Tools -> DownThemAll! Tools

formats. While it’s not as feature-rich as Excel, its data analysis
capabilities are on par and it is very nimble and fast. URL:
- Sticky Notes: Jot down notes for later on post-it type pads that you
can put on your desktop.
- Text Editor: Edit text files with medit. This is the more powerful
one of the two text editors available in Naviagtrix. medit knows
different high-lighting modes (for various programming and mark-up
languages, e.g. XML and HTML), can do spell checking, and can be
extended via external tools. The full manual for medit is available
under the application’s Help menu. The other editor that comes with
Navigatrix is Leafpad - no frills but lightning quick. Leafpad is not
accessible through the Manta Menu but by default a double-click on a
text document in the File Manager will open it in Leafpad. URL:
- Wikipedia: Read wikipedia offline with Kiwix. A great tool if you’re
in places where the internet is not as ubiquitous. Kiwix is the
reader application. To get wikipedia content you’ll have download one
of the data files (“ZIM files”) available at the Kiwix
These files contain compressed wikipedia content and are available in
several languages. An English version with a selection of 45,000
articles (pulled from wikipedia in December 2010) is about 3.7 GB to
download. An English version with all wikipedia articles as of
January 2012 (but without pictures) is 10 GB to download. Keep in
mind though, that USB sticks and SD cards typically don’t allow
individual files to exceed 4GB. Hence the 10 GB version will only
work from a harddisk. URL: www.kiwix.org
- Word Processor: Compose, edit, and view documents with AbiWord.
AbiWord can read and save MS Word and Open Document formats (and many
more). URL: www.abisource.com
Sound and Video

Airmail: Check you SSB eMails with Airmail. This is the Windows
application running under Wine (see Installing Windows Applications).
You configure and use the program in the same way as you do under Windows.
Navigatrix also keeps your position data in Airmail updated with your GPS
position (see GPS and Navigatrix). If you use Airmail with a Pactor modem via USB or
Bluetooth Navigatrix will automatically configure the required com ports.
For this to work you need to power on your modem while it is connected to
your computer but before you start Airmail. If you’re new to Airmail:
There is a good introduction and “how-to” guide available from the Sailmail
website at http://www.sailmail.com/smprimer.htm.
Note: Some early versions of Navigatrix version 0.5 had a small
error in the script that handled the automatic com port set-up. If
you experience trouble with the automatic com port configuration in Airmail
please check this post in the Navigatrix
