                        Satellite geodesy is the measurement of the form and dimensions
                  of the Earth, the location of objects on its surface and the figure of the
                  Earth's  gravity  field  by  means  of  artificial  satellite  techniques.  It

                  belongs  to  the  broader  field  of  space  geodesy,  which  also  includes
                  such techniques as geodetic very long baseline interferometry (VLBI)
                  and lunar laser ranging.

                        The application of geodetic satellite methods is determined by the
                  achievable  accuracy,  the  necessary  effort  and  expense  of  equipment
                  and computation, and finally by the observation time and the ease of
                  equipment handling.

                        Satellite geodesy is used to show:
                        −  general  shape  of  the  Earth’s  figure  and  the  gravity  field,  −
                  dimensions  of  a  mean  Earth  ellipsoid,  −  establishment  of  a  global

                  terrestrial reference frame, − detailed geoid as a reference surface on
                  land  and  at  sea,  −  connection  between  different  existing  geodetic
                                                             205
