From the global SLR data of Lageos between 1983 and 1986 inclusive, two series of the draglike coefficient C(D) were obtained. The first one uses simultaneous estimation of the initial state vector of the satellite, C(D), and the solar radiation pressure coefficient C(R) for each 15-d arc; the second uses multiarc estimation with 10-d orbital state, C(D), C(R), and 5-d ERP. The Marple algorithm for AR spectra was applied to both series, the first series giving the periods 475.5, 365.2, 216.4, 183.4, 69.0, 39.9, and 32.25 d; the second, 173.3, 152.8, 127.6, 61.3, and 27.64 d.
