# RTKLIB Touchscreen GUI

RTKLIB GUI (Graphic User Interface) for Raspberry Pi with touchscreen made with Qt4 by the ENSG students

Update news : February 2019 update

Added ntrip server option in base mode, choose ntrips in output stream and give a ntrip server path (tested with rtk2go.com).The default string goes to rtk2go.com caster with Myplace as mountpoint, just change the mountpoint name and add your receiver info with -i "Ublox-M8T,3.27,00001" (firt string is receiver name, second string is firmware version, third string is serial number, station info with -sta "your station info" is not working yet on rtk2go)
Added a install script pack, tested on raspbian stretch and a RPI3you can get it with wget https://github.com/Francklin2/RTKLIB_Touchscreen_GUI/raw/master/RTKbase_installer.zip
the ENSG project for this year is to convert the C++ code into a python script based on the Taroz TouchRTKStation ( https://github.com/taroz/TouchRTKStation ) the release should be around May
You can type in a EPSG in the save point options, use the syntax EPSG:xxxx (example EPSG:4236) to get a projection transform with cs2cs in you saves point files (no virtual keyboard yet, you have to have a USB one))

May 2018 update

Added autostart a rover mode at boot, new button and page on main screen to set boot options
New branch to keep a Qt4 version compatible wth RPI2, now master branch is under QT5
Added geoid correction file option in the rover mode >> status >> save point option

March 2018 update

Add post processing on USA CORS stations, still under test but process looks correct now (still need a test from US to confirm that) (Video here)
Median position is done by average of the XYZ results
More info on the screen on the download process, progress bar is more precise, debug window is on another tab

February 2018 update

Automatic post processing to get base position, only compatible on desktop PC and RPI3 with Qt5 installed(still working on QT4/RPI2 compatibility). Works with european RGP ign server. It check for the nearest stations and download and process from 1 to 6 stations, if more than one station is used a median position is calculated.
Automatic mode with data logging>>post processing>>base station in one click, switch ost processing, put "Autostart base after processing" to "on" to enable else it will just give the results

August 2017 update

new pages in the wiki : tips and tools, test results by the ENG students
added data logging from the GNSS for post processing, just choose file in output of the basestation and it's done
added save position option, you are able to save X points ypu want to record with choosen timing
added 8 custom configuration files to the original preset
added you can edit edit most of the RTKlib parameter with the gui for the 8 custom config
added display of system and GNSS time and date in solution status windows
added Push button to set PI system date and time with GPS date and time
issue : return button in edit interface may freeze the software sometimes, allway lauch a configuration after you edited one then stop to avoid that

Installation

For raspberry PI 3 (based on raspbian stretch) https://drive.google.com/open?id=1HOssKfLAgLO0DKe1ZVBqeMXHCmyP4w-P

Copy this image on a SD card, you can use Rufus for that : https://rufus.akeo.ie/
Insert the SD card in your Raspberry Pi and start it.

Install manually RTKBASE on a fresh image of Raspbian (tested on strech):
Open the terminal
do a sudo apt-get update and sudo apt-get upgrade
Download install scripts with: wget https://github.com/Francklin2/RTKLIB_Touchscreen_GUI/raw/master/RTKbase_installer.zip
- Unzip the installer file in home directory (/home/pi)
- Go to the folder /home/pi/Installer
- Update rights for the 3 scriptswith chmod +x 1-Download_rtkbase.sh chmod +x 2-Build_rtkbase.sh chmod +x 4-Install_LCD_driver.sh
- Lauch the 3 scripts in order to 1 downmload and build RTKbase 2 Install autostart and 3 install driver
You can do it manually with:
- clone the repository: git clone https://github.com/Francklin2/RTKLIB_Touchscreen_GUI
Go to the RTKBASE directory: cd RTKLIB_Touchscreen_GUI/RTKBASE/
Run the script to compil: ./build_rtkbase_Qt5_ARM.sh ( or ./build_rtkbase_Qt5_x86.sh on a desktop x86 PC )
Launch RTKBASE: ./RTKBASE

To install system on a raspberry pi 2 with the touchscreen you can download a raspian image with all the touchscreen drivers, Qt4 and all compilation dependencies preinstalled here :

https://drive.google.com/file/d/0B5xmVAi4jATOcXE3a3BWS0VDUUk/view?usp=sharing

It was based on this original image with only the library for the touchscreen: https://drive.google.com/file/d/0B2SuLGFxizpVMzRtODVkN0tZVjA/view?usp=sharing

You can also download these Pré-installed image of RTKbase, RPI2 contain a master version (june 2016) with autoload and custom splash screen, the version for RPI3 contains Raspbian Jessie with drivers and the Beta version(august 2017)

For raspberry PI 2 https://drive.google.com/open?id=0B5xmVAi4jATOcEQ1TWxaOXprMk0

Autostart RTKBASE at boot :

Very simple but many method to do it :

1) Add software to rc.local Run :

sed -i -e '$i \cd /home/pi/RTKLIB_Touchscreen_GUI/RTKBASE/ && RTKBASE\n' rc.local

2) Use system root LXDE autostart : Run :

sudo nano /etc/xdg/lxsession/LXDE-pi/autostart

Add this :

@/home/pi/RTKLIB_Touchscreen_GUI/RTKBASE/
@RTKBASE

3) Use user LXDE autostart : Run :

nano ~/.config/lxsession/LXDE/autostart

Add this :

@/home/pi/RTKLIB_Touchscreen_GUI/RTKBASE/
@RTKBASE

4) Add desktop entry to user config : Run :

nano ~/.config/autostart/rtkbase

Copy paste entry below :

[Desktop Entry]
Name=RTKBASE
Type=Application
Comment=RTKLIB Touchscreen : graphic interface to use GNSS.
Exec=/home/pi/RTKLIB_Touchscreen_GUI/RTKBASE/RTKBASE
Make it executable : 
chmod +x ~/.config/autostart/rtkbase

Best way for me is option 4 because I do not use LXDE

Add a custom splash screen at boot

Install fbi

sudo apt-get install fbi

Copy the splash image splash.png from /Splashscreen to /etc/
Copy the asplashscreen file in /Splashscreen to /etc/init.d/ Make the script executable and install it for init mode:

sudo chmod a+x /etc/init.d/asplashscreen sudo insserv /etc/init.d/asplashscreen

To remove text message edit /boot/cmdline.txt change console=tty1 to console=tty3 and add loglevel=3 at the end of file
