The epoch of supremacy of CCD technique allows us to elaborate a new approach to the problem of observations of any celestial 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 derivatives of its spherical coordinates by means of statistical treatment in a real time during CCD observations. The classic Laplace 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 important additional values for an identification of the observed object. The algorithms and software were developed in Pulkovo observatory for the fast analysis of any CCD frame where the moving celestial objects were detected.
