The project includes not only the airborne hardware and software, from voltage regulators and GPS receivers to Kalman filtering code, but also a powerful and ever-expanding array of ground hardware and software including modems, antennas, and a highly evolved user-friendly ground control software interface. All hardware and software is open-source and freely available to anyone under the GPL. The key feature of the Paparazzi autopilot is its unique combination of infrared thermopiles and inertial measurement for attitude sensing, providing a robust and accurate attitude estimate that requires no ground calibration and can recover from any launch attitude. %G English %L hal-00938858 %U https://enac.hal.science/hal-00938858 %~ ENAC %~ DRONES %~ TDS-MACS
