Measurement Uncertainty of Schumann Resonances with the EFIELD Experiment on Board Dragonfly

Résumé

EFIELD sensors on board the Geophysical and Meteorological package (DraGMet) of the NASA Dragonfly mission will passively record the time-varying electrical field on Saturn's largest moon: Titan. The main goal of these sensors is to detect Schumann Resonances (SR), which propagates between the ionized atmospheric layer and a subsurface layer, presumably a salty water ocean. Measuring these electromagnetic resonances allows us to determine the characteristics of the cavity and especially the ocean depth, which is crucial to assess the habitability of Titan. This work describes the analytical developments and numerical simulations we performed to assess the measurement uncertainty of the EFIELD probes.
