description The tracking system of the CMS detector provides excellent resolution for charged particle tracks and an efficient way of tagging jets. In order to reconstruct good quality tracks, the position and orientation of each silicon pixel and strip module needs to be determined with a precision of several micrometers. The presented alignment results are derived following a global (Millepede-II) and a local (HipPy) fit approach. The performance of the CMS tracker alignment in 2016 using cosmic-ray data and the complete set of proton-proton collision data recorded at 3.8 T magnetic field has been studied. The data-driven validation of the results are shown. The time-dependent movement of the pixel detector's large-scale structure is demonstrated.
