On aperture averaging effects for central obscured telescopes: experimental validation with ARTEMIS experimental downlink measurements Nikolaos Lyras Charilaos Kourogiorgas Athanasios Panagopoulos Konstantinos Liolis et al. ABSTRACT In this paper, a methodology for the estimation of aperture averaging factor for a central obscured aperture is briefly presented and tested against experimental results. The modeling is based on the methodology reported in the NASA's report edited by Fried [10] .

Experimental data sessions from 2003 with the ARTEMIS GEO satellite as space segment and the 1.016m Cassegrain central obscured telescope of ESA in Tenerife at 2.4km altitude as ground segment are used.
