Characterization and compensation of magnetic interference resulting from unmanned aircraft systems [PDF]

open access: yes, 2019
Unmanned aircraft systems (UAS) are a viable platform for aeromagnetic surveys but the interference generated during flight can greatly impact data quality. In this thesis, the problem of interference reduction was approached from two directions: mapping
