The navigation suite of the balloon-borne neutrino detector PUEO
POSTER
Abstract
PUEO (the Payload for Ultrahigh Energy Observations) will fly from McMurdo Station, Antarctica during the 2025 austral summer.
It is designed to detect Askaryan radio emission resulting from the interactions of ultrahigh energy (>1 EeV) neutrinos with the Antarctic ice sheet.
In order to accurately project events onto the continent for both reconstruction of incident neutrino geometry and background rejection, PUEO needs a high precision pointing system, with angular resolution of 0.05° in heading, pitch, and roll.
To achieve this during the course of a multiweek flight, PUEO will fly a suite of navigation instruments that rely on a variety of observables; this suite will include inertial navigation systems, a differential GNSS unit, sun sensors, star trackers, and a magnetometer.
These each come with their own benefits and considerations, and will be utilized both during flight for monitoring and post-processed during analysis and neutrino searches.
