  Doppler effect and Hubble effect in different models of space-time related to
the space-time velocity of an observer are considered. The Doppler effect and
Doppler shift frequency parameter are connected with the kinematic
characteristics of the relative velocity and the relative acceleration of the
emitter with respect to the observer (detector). The Hubble effect and Hubble
shift frequency parameter are considered in analogous way. It is shown that by
the use of the variation of the shift frequency parameter during a time period,
considered locally in the proper frame of reference of an observer, one can
directly determine the radial (centrifugal, centripetal) relative velocity and
acceleration as well as the tangential (Coriolis) relative velocity and
acceleration of an astronomical object moving relatively to the observer. All
results are obtained on purely kinematic basis without taking into account the
dynamic reasons for the considered effect. PACS numbers: 98.80.Jk; 98.62.Py;
