New conception of the moving celestial object observations

摘要

The epoch of supremacy of CCD technique allows us to elaboratre a new approach to the problem of observations of any celectial body moving on the background of stars. Using the computerized star catalogues one can calculate several astrometric positions for any moving celestial object, the first and sometimes the second drivatives of its spherical coordinates by means of statistical treatment in a real time during CCD observations. The classic Lapace method for initial orbit determination may be successfully used now. These derivatives and also so called the Apparent motion Parameters, namely topocentric angular velocity and acceleration, positional angle of motion and curvature of object's trajectory are the inportant additional values for an identification of the observed object. The algorithms and software were developed in Pulkovo observatory for th fast analysis of any CCD framew where the moving celestial objects were detected.
