- A complete boat navigation system
- Includes OpenCPN, Chart plotter navigation
- OpenSource, so it's free !
- Running on Raspberry Pi
- Its hardware is cheap
- Running on Unix, so its reliable
- It comes with NOOBS(New Out Of Box Software) which makes it very simple to install
Its also a compilation of several other nice software which makes it a fantastic package for additional functions.
The Openplotter WEB-site, the nice forum with active people and god documentation makes it almost easy, but if You are a newbie to both OpenPlotter(OP) and OpenCPN(OC), as I was, it can be to much.....
So I'm trying to do a compact guide with links to the documentation and, hopefully, a fast way to be up and running.
Start up with checking what You need
Probably You are doing the first setup at home so you don't have any hardware connected to Your boat network, but thats no problem. We will take care of them later.
SignalK is mentioned several times in the documentation and You should know that this is the "engine" in OP, but for now thats all You have to know.
Install the programs. For the the moment, 2017-07-17 the RPI v0.10.0 NOOBS is the latest. I prefer the headless install which works very well. On my RPi 3 it took about 10 minutes before the WiFi "OpenPlotter" appeared which used the built in WiFi hardware.
Connect to the Rpi. I used the "VNC Viewer" on my Mac which also works great on an iPad.
Go back and complete the settings at the end of the document
If necessary change the resolution
"Preferences" => "RPi Config" => "System" => "Set Resolution".
I picked => DMT mode 16, 1024 x 768 to work together with my Mac
Before You continue please update the software to the latest release. Start with "Upgrade Rasbian" which is the operating system. After a reboot continue with OP update. Changelog is found here. I recommend the "OpenPlotter beta update" so You get the latest software. Despite it's called a Beta it is very stable.
To check that OpenCPN, the plotter, works, without any NMEA physical input we use the "NMEA 0183 generator"
Start the OP application by clicking on the "Anchor" symbol in the upper part of the window
Go to the "Tools" Meny and klick on "NMEA 0183 generator". At the end of document there is a guide. Klick on "add" and select "RMC" from the sentence drop down list and "1" from the Rate(sec) drop down.
RMC means Recommended Minimum Navigation Information and are a sentence sent from an GPS. If You click on the "NMEA info" button You will have an explanaition for all valid sentences. WEB link
Add "Type" and "Value" to respective field
|Timestamp||Number||100000||24 hour clock|
|Speed Over Ground||Number||5|
|Magnetic Variation Direction
and finish with a click on the "OK" button
Open OC by clicking on the icon on the desktop. Klick on the "drop", "Auto Follow", in the meny at the top and You should see a worldmap with Your Boat placed in the south of Sweden.
In the lower left part of the OC window You will see the actual coordinates, SOG, speed over ground and COG, Course over ground.
This ends the initial installation. Moore posts will follow.
