Task 3. Answer the questions to the text.
                        1. What are the satellite geodetic methods determined by?

                        2. What spheres is satellite geodesy applied in?
                        3. What are the main goals of satellite geodesy?

                        4. How  is  satellite  geodesy  used  for  geodetic  control  and
                  geodynamics?
                        5. Are the satellite geodetic technologies used in navigation and
                  marine geodesy? How?


                        Task 4. Define whether the following statements are true or
                        false and translate them. Correct the false ones according to

                        the text.

                        1.  Satellite  geodesy  includes  geodetic  very  long  baseline
                  interferometry and lunar laser ranging.
                        2. Satellite geodesy is not used to measure crustal dynamics and

                  polar motion.
                        3.  Satellite geodesy is used for establishing geodetic connections
                  between islands or with the mainland.

                        4. Main goal of satellite geodesy is the determination of the figure
                  of the Earth, positioning and navigation.
                        5. Surveyors  have  never  used  satellite  geodetic  methods  for
                  detailed plane surveying.


                                       Main techniques of satellite geodesy

                        Task  1.  Read and  memorize  the following  words and word-

                        combinations:

                             payload – корисний;
                             radar altimetry – радіолокаційна альтиметрія;
                             spaceborne laser – космічний лазер;

                             retroreflector – ретрорефлектор;
                             instantaneous – миттєвий, моментальний;
                             orbit perturbation – пертурбація орбіт;
                             calibration – калібрування, перевірка;

                             radial velocity – радіальна скорість;
                             constellation – сузіря, плеяда;
                             circular orbit – кругова орбіта;

                             time transfer – час переміщення;
                             pseudorange – помилковий, фальшивий.
