Inner Detector alignment development and performance in preparation for Run 3

Several major changes were introduced in the ATLAS track reconstruction software to deal with the challenges posed by the Run 3 of the Large Hadron Collider, necessitating a new detector alignment campaign. The re-alignment results are shown to be stable over Run 2 and to have smaller remaining biases than the previous iteration. In addition, new methods were introduced for determining the track momentum biases, based on $Z\rightarrow\mu^{+}\mu^{-}$ events. The refined detector description will improve future data analysis performed with Run~2 and Run~3 data.
