Description
The Payload for Ultrahigh Energy Observations (PUEO) is a long duration balloon
experiment that flew over Antarctica for 23 days from December 2025 to January
2026. Approximately 24 hours after the launch of the PUEO, two high altitude
calibration balloon payloads (HiCal3a and HiCal 3b) were launched and followed
the PUEO. The HiCal payloads contained high voltage pulse generators that
transmitted signals in both vertical and horizontal polarizations. These signals
were captured by the PUEO during flight and are being used to calibrate the
instrument. This talk will present the design and flight of the HiCal payloads
as well as ongoing analysis of HiCal calibration signals.
