Precision laser tracking data on three close-earth satellites Geos 1, Geos 2, and Lageos are analyzed to obtain measurements of ocean tides, body tides, including the core-mantle resonance and other mass displacements, from perturbations of the node and inclination. Mean elements are computed for 6.0 years for Geos 1, 4.9 years for Geos 2, and 2.1 years for Lageos. Ocean tides T2, S2, K2, P1, K1, and phi 1 are measured, along with the core mantle resonance at the K1 frequency, as predicted by Poincare, Molodensky and Wahr. The semi-annual body tide deformation is measured. The radiation pressure area to mass ratio for the three satellites is also measured. Author
