Introduction

Magnetic surveying is an established method in archaeological prospection, and it has been continuously improved in the last few decades thanks to technical progress in measurement equipment. Modern systems can map magnetic field variations with high accuracy and spatial resolution. One of the latest developments in magnetic surveying is the use of unmanned aerial vehicles (UAV) as measurement platforms. UAV-borne magnetic measurements have proven to be a valid method to map magnetic fields. They enable data acquisition in harsh terrain and unsafe areas, like volcanological studies (Gailler et al., 2021) or detection of unexploded ordnance (Gavazzi et al., 2016). However, the potential of UAV-borne magnetic surveys for archaeological prospection has hardly been explored so far (but see Schmidt et al., 2020). Archaeomagnetic prospection requires an accurate, fine-spaced sampling of the magnetic field close to the ground. These requirements are challenging for UAV-borne me...
