Beside the fun of designing and building the models, they also wanted to measure data during the flight and send them in realtime to a ground station. As ground station a laptop with an Sensor-Terminal-Board from dresden elektronik was used. This boards have the advantage that they use a parallel to USB converter FT245BM, that allows high data rates between the microcontroller and the PC. The live data was written to logfiles and postprocessed later to get the resulting graphs and diagramms.
