Install TouchRTKStation

  1. Connect the Raspberry Pi to the internet.
  2. Download the TouchRTKStation
    $ cd /home/pi/
    $ git clone https://github.com/taroz/TouchRTKStation.git
  3. Connect the 4inch touch screen to the Raspberry Pi. Run Install.sh
    $ cd /home/pi/TouchRTKStation/install
    $ sudo sh Install.sh
  4. 4inch touch screen is enabled. If you want to return back to HDMI output,
    $ cd LCD-show
    ./LCD-hdmi
  5. Run TouchRTKStation
    $ sudo python3 /home/pi/TouchRTKStation/TouchRTKStation.py
  6. If you want to quit the TouchRTKStation, use Alt+F4
  7. If you want to automatically start the TouchRTKStation
    $ cd /home/pi/TouchRTKStation/install
    $ sudo sh Autostart.sh

How to use

  1. Insert a USB memory to the Raspberry Pi. GNSS raw data (.ubx file) is stored in the USB memory. In the rover mode, positioning results (.pos file) are also stored. If there is no USB memory, GNSS data are stored in the home directory of the Raspberry Pi.
  2. To connect NTRIP caster or NTRIP server in the rover mode, or to connect a rover in the base mode, a network connection via WiFI is needed. The wireless communication device such as ZigBee dongle, which can be recognize as USB serial port, is also can be used.

Rover mode

  1. Select “Rover” tab. Select “Single”，”RTK(Static)”, or “RTK(Kinematic)”
  2. Push “Config”. For RTK-GNSS, setup the input stream information in the “Correction1” tab. If ZigBee or any wireless communication device, which are recognized as USB serial port, is used to receive the GNSS data, setup the input stream information in “Correction2” tab. In the “BasePos” tab, input the base sanitation position．
  3. Push “Start”. Positioning results will be shown after GNSS ephemeris data are decoded.
  4. Push “Stop”. GNSS Raw data and positioning result are stored in the USB memory.

Base mode

  1. Select “Base” tab.
  2. Push “Config”. To broadcast GNSS correction data, setup a output stream information in the “Output1” tab. If ZigBee or any wireless communication device, which are recognized as USB serial port, is used to transmit the GNSS data, setup the output stream information in “Output2” tab. If you want to convert the UBX format to the RTCM format, input the base station position in "BasePos” tab.
  3. Push “Start”. GNSS data will be stored or broadcasted.
  4. Push “Stop”. GNSS Raw data are stored in the USB memory.
