Overview

ground_station is a GUI based on GTK+ allowing to display/update data provided by some ROS topics. Given that the CityFlyer platform is a quadrotor (i.e. Pelican built by Ascending Technologies GmbH - http://www.asctec.de) we have developed several GTK+ widgets capable of display telemetry data. These widgets are made to look like to real flight instruments in order to allow easy feedbacks for the user/pilot.

For more details about these widgets and how to use them, check out the doxygen documentation available in the Code API section.

Usage

The ground station GUI can be started by running:

   1 roslaunch ground_station ground_station.launch

The telemetry demo can be started by running:

   1 roslaunch ground_station telemetry.launch

Nodes

groundstation

The is the first version of the CityFlyer ground station. In this version, the GUI is devided into 3 tabs. The first one showing the telemtry widgets needed. The second tab is quite the same as gpsd_viewer. And the third tab provide an easy way to record bags.ground_station_telemetry.pngground_station_gps.pngground_station_rec.png
