Satellite signatures in SLR observations

Abstract

We examine the evidence for the detection of satellite-dependent signatures in the laser range observations obtained by the UK single-photon Satellite Laser Ranging (SLR) System models of the expected observation distributions from Ajisai and Lageos are developed from the published satellite spread functions and from the characteristics of the SLR System and compared with the observations. The effects of varying return strengths are discussed using the models and by experimental observations of Ajisai, during which a range of return levels from single to multiple photons is achieved. The implications of these results for system-dependent center for mass corrections are discussed
