N2 - We analyze the kinematics of disk planetary nebulae (PNe) to derive the formal Galactic center distance, R 0, for three catalogues of PNe distances. Then we correct the catalogues' distance scales renormalizing the PNe distances by the ratios of formal R 0 values to a best modern value of R 0 =7.9 kpc. The created new catalogue of disk's PNe distances was found to be in a good agreement with distances by Stanghellini et al. (2008). Our catalogue of PNe distances was used to recalibrate the statistical distance scale for all Galactic PNe.
