UAVs can easily reach the auto-collimation points of optical components of the next class of Extremely Large Telescopes. They can be equipped with tools for the measurement of the co-phasing, scattering, and reflectivity of segmented mirrors or environmental parameters like C2n and C2T to characterize the seeing during both the day and the night.ELETTRONICOenUnmanned aerial vehicles in astronomyConference paper10.1117/12.22328072-s2.0-84996791612000387747900031https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9912/1/Unmanned-aerial-vehicles-in-astronomy/10.1117/12.2232807.short?SSO=12016SPIE.9912E..10BFIS/05 - ASTRONOMIA E ASTROFISICA
