Satellite Laser Ranging (SLR) measurements of the geodynamic satellite LAGEOS-1 (LAser GEOdynamics Satellite) for the period January 2000 - June 2013 are processed and analyzed. The analysis are carried out with the Satellite Laser Ranging Processor (SLRP) software, version 4.3, developed in the Department Geodesy of the National Institute of Geophysics, Geodesy and Geography at Bulgarian Academy of Sciences. A new module for parameter estimation using the least squares method was developed to allow flexible treatment and combination of observational equations - from elimination of parameters to sequential estimation. Through sequential estimation, total number of 202 447 measurements are processed and analyzed. Coordinates and velocities of 37 stations located on the main tectonic plates are estimated. Along with the site?s coordinates and velocities, arc dependant parameters, geogravitational parameter - GM, Earth Orientation Parameters (pole coordinates and length of the day - LOD) are also determined. The root mean square of the multiyear solution is 10 cm. The results obtained are contribution to the monitoring of recent tectonics of the major continental plates.
