Drone-Based Calibration of Radio Antennas at the Pierre Auger Observatory. — Martin Erdmann, •Alex Reuzki, and Maximilian Straub — III. Physikalisches Institut A, RWTH Aachen University

Ultra-high-energy cosmic rays induce extensive air showers in the Earth's atmosphere. At the Pierre Auger Observatory, those air showers are measured using various detection techniques including Radio detection with Short Aperiodic Loaded Loop Antennas (SALLA) as part of the AugerPrime upgrade.

The SALLA's antenna pattern has been described using simulations and an absolute calibration has been performed utilizing the galactic radio background. Here we introduce a direction-dependent calibration procedure, which uses a well-defined biconical antenna mounted to a drone with active stabilization and precise position tracking. The drone setup allows us to precisely extract the antenna sensitivity from any direction and distance. With that, we performed calibration measurements on a SALLA. First results are presented.
