Hypertemporal photometric measurement of spaceborne mirrors specular reflectivity for Laser Time Transfer link model
D Kucharski, G Kirchner, T Otsubo, H Kunimori… - Advances in Space …, 2019 - Elsevier
The hypertemporal light curves of the sunlit Ajisai satellite allow for reflectivity measurement
of the individual on-board mirror panels. The photon counting technology developed at Graz
Satellite Laser Ranging (SLR) station makes it possible to distinguish between the solar flux
diffused and specularly reflected off the spinning Ajisai. The flux intensities measured at 10
kHz sampling rate during the period from Oct. 2015 until Jan. 2018 are analyzed through the
spacecraft micro-model link budget equation and indicate reflectivity of the 149 mirrors of …
