Five years of laser data (1984-88) between the Lageos satellite and the ground station network based on precise monthly computations of the Lageos satellite are analyzed to recover tectonic motions affecting the stations. A global inversion over this period provides solutions for absolute velocities in latitude and longitude of a selected subset of 14 stations. Relative horizontal velocities are derived between couples of stations located on different tectonic plates and are compared to predictions of the NUVEL-1 geological model. Quality of agreement between the Lageos solution and the model depends on the distance between the stations and the plate boundaries. Topics discussed include the earth's gravitational potential, luni-solar and planetary perturbations, direct and earth-reflected radiation pressure, atmospheric drag and charged particle drag, solid and ocean tides, and a celestial reference system.
