Analytical Studies of Laser Parameters for Ranging and Illuminating Satellites from H-SLR Station
Space Research Journal, 2010 In this paper, the laser system used at the Helwan Satellite Laser Ranging Station (H-SLR) will be used in satellite's illumination as well as for satellite ranging. The estimated model which describes the energy and number of photons as well as the number of photoelectrons are investigated from the received signals of laser beam.
