Determination of SLR station coordinates based on LEO, LARES, LAGEOS, and Galileo satellites

Abstract The number of satellites equipped with retroreflectors dedicated to Satellite Laser Ranging (SLR) increases simultaneously the development and invention spherical geodetic satellites, low Earth orbiters (LEOs), Galileo other components Global Navigational System (GNSS). SLR GNSS techniques onboard LEO create possibility widening use observations for deriving station coordinates, which up now have been typically based on satellites. We determine coordinates integrated LEOs, geodetic, orbiting at different altitudes, from 330 26,210 km. combination eight LAGEOS-1/2, LARES, 13 increased 7-day solutions 10–20% even 50%. discuss issues handling range biases in multi-satellite combinations proper solution constraining weighting.
