Scientific paper

A data base containing time and latitude observations from 1904 to the present has been created in Pulkovo (PDB). The PDB archives more than 700,000 primary astrometric observations of stars made by nine photoelectric transit instruments (PTI) and by three zenith tubes, together with corresponding meteorological data. The PDB is a specialized object-oriented data base supplied with a GUI and having a wide range of specific scientific applications: calculation of any ephemeris data and fundamental arguments, initial time and latitude reductions of the PDB data sets in IERS standard, calculation and analysis of time and latitude residuals relative to any global solutions of EOP IERS, search for some geodynamic, refraction, and instrumental effects, and construction of a system of adjusted positions and proper motions in right ascension from PTI data, etc. Possible PDB applications: interaction of earthquakes and polar motion, excitation mechanism of Chandler's motion and its possible composed character, secular drift of the pole, and the influence of ocean streams on the Earth's rotation and polar motion.
