2. Ground Control Station
3. QGroundControl • Main Features • Open-source MAVLink Micro Air Vehicle Communication Protocol with lightweight serialization functions for microcontrollers • Windows / Linux / MacOS support • 2/3D aerial maps (Google Earth support) with drag-and-drop waypoints • In-flight manipulation of waypoints and onboard parameters (in EEPROM) • Real-time plotting of sensor and telemetry data • Logging and plotting of sensor logs • Support for UDP, serial (radio modem) and mesh networks • Supports multiple Autopilots (pxIMU, ArduPilotMega, SLUGS, MatrixPilot/UAVDevBoard, many more) • MAVLink protocol supports up to 255 vehicles in parallel and project-specific custom messages can be added • Head-up-display, support for digital video transmission/display • Competition-proven at IMAV and EMAV competitions (QGroundControl was used in the EMAV 2009 1st place Indoor Autonomy entry)
4. Dependency Package • Qt5.4 and SDL1.2 • git and some essential packages for building
5. Installation Guide • Environment: Ubuntu 14.04 LTS 1. sudo add-apt-repository ppa:beineri/opt-qt541-trusty 2. sudo apt-get update && sudo apt-get install qt54tools qt54base qt54declarative qt54serialport qt54svg qt54webkit qt54quickcontrols qt54xmlpatterns qt54x11extras qt54websockets qt54sensors qt54script qt54quick1 qt54qbs qt54multimedia qt54location qt54imageformats qt54graphicaleffects qt54creator qt54connectivity libsdl1.2-dev libudev- dev 3. source /opt/qt54/bin/qt54-env.sh 4. echo $PATH && echo $QTDIR 5. git clone https://github.com/mavlink/qgroundcontrol.git (on your own workspace directory) 6. qmake (on qgroundcontrol directory) 7. make (on qgroundcontrol directory)
6. Flashing on QGroundControl • Execute QGroundControl ~ sudo ./qgroundcontrol (on qgroundcontrol/release after building QGroundControl) • Set an image to flash • Push ‘Upgrade’ button after unplug the device • Plug the device
7. Issues • Qt version ~ install Qt5.4 • Permission to connect the device ~ sudo chmod 666 /dev/ttyACM0 • Unstable upgrading ~ ambiguous, operated occasionally
