Over 4,000 exoplanets have been identified and thousands of candidates are tobe confirmed. The relations between the characteristics of these planetarysystems and the kinematics, Galactic components, and ages of their host starshave yet to be well explored. Aiming to addressing these questions, we conducta research project, dubbed as PAST (Planets Across Space and Time). To do this,one of the key steps is to accurately characterize the planet host stars. Inthis paper, the Paper I of the PAST series, we revisit the kinematic method forclassification of Galactic components and extend the applicable range ofvelocity ellipsoid from about 100 pc to 1, 500 pc from the sun in order tocover most known planet hosts. Furthermore, we revisit the Age-Velocitydispersion Relation (AVR), which allows us to derive kinematic age with atypical uncertainty of 10-20% for an ensemble of stars. Applying the aboverevised methods, we present a catalog of kinematic properties (i.e. Galacticpositions, velocities, the relative membership probabilities among the thindisk, thick disk, Hercules stream, and the halo) as well as other basic stellarparameters for 2,174 host stars of 2,872 planets by combining data from Gaia,LAMOST, APOGEE, RAVE, and the NASA exoplanet archive. The revised kinematicmethod and AVR as well as the stellar catalog of kinematic properties and ageslay foundation for future studies on exoplanets from two dimensions of spaceand time in the Galactic context.
