Spin parameters of LAGEOS-1 and LAGEOS-2 spectrally determined from Satellite Laser Ranging data

Applying the apparent corrections to the observed spin rates allows to identify precession of the spin axes of the satellites around the southern pole of the inertial reference frame. The direction of rotation around the spin axis of LAGEOS-1 is clockwise, and counter-clockwise for LAGEOS-2. The obtained results are compared (and present good agreement) with the predictions given by the LOSSAM model.
