Paper 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]. For the validation of the methodology, experimental data from the ARTEMIS bi-directional optical link is employed. 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.
