Then we estimate the global rotation between TGAS with {\\it Tycho}-2 proper motion systems to investigate the property of the {\\it Gaia} DR1 reference frame. Finally, the Galactic kinematics analysis using the K-M giant proper motions is performed to understand the property of {\\it Gaia} DR1 reference frame.
