The ATH-PA ( Afficheur Tête Haute ) or HUD ( Head Up Display ) is one of the most important tool for the UAV pilot. The ATH system can be fully integrated in the pilot helmet or in the ground station. In this new version v3.0 of the ATH-PA, there is an Auto-Pilot: the onboard micro-controller (MCU) is able to steer the UAV according to a stored flight plan. All the GPS datas and the flight video are sent in real time to the ground station. At any time during an autonomous flight mission, the pilot is able to switch off the Auto-Pilot from UAV mode (Unmanned Aircraft Vehicle) to RPV mode (Remote Piloted Vehicle) so as to retreive the full control of the aircraft. This new version is a major step in the ATH project compared to the previous version v2.3.
