Use of UASs for Outdoor Diagnostics of Large Antennas

Unmanned aerial systems (UASs) enable the in situ diagnostic of antennas operated in outdoor environments. Additionally, their flexibility introduce the possibility of performing several diagnostic methods that were not possible before. In this work, the challenges of performing outdoor measurements with UASs are discussed and some of the possibilities they introduce are outlined, such as subreflector calibration and satellite emulation.
