Abstract: We present a method to derive kinematic parameters for the Galactic thick and thin disks of the Milky Way (MW) based on the Radial Velocity Experiment (RAVE Steinmetz et al. 2006). We introduce selection criteria in order to clean the observed radial velocities from the Galactic large scale effects and to take into account the partial sky coverage of RAVE. The data are disentangled from a mixture of thin and thick disk stars as explained in a forthcoming paper (Pasetto et al. 2012) on the basis of pure kinematics arguments and supplied with photometric distances and proper motions. We deduce the components of the Solar motion relative to the Local Standard of Rest (LSR) in the radial and vertical directions as well as the components of the velocity dispersion tensors for the two MW component on the basis of pure kinematics arguments. The selected sample is a limited subsample from the RAVE catalogue roughly extending 500 pc above and below the Galactic plane. This sample tracks the velocity dispersion trend in radial direction to 1 kpc within and 500pc outside the Solar radius in the Galactic reference system.
