I present a kinematic analysis of the Galactic thin and thick disks based on RAdial Velocity Experiment (RAVE). Thin and thick disk components are considered as two distinct galactic populations and disentangled from their mixture with analytical and statistical method. The prospects and limitations of this method are explored with the use of photometric distances and proper motions and compared with a phase-space synthetic Galactic model. I deduced the components of the solar motion relative to the local standard of rest in the radial and vertical direction, the velocity lag of the thick disk and the components of the velocity dispersion tensor for the thin and thick disk in the meridional plane.
