Terrestrial geodesy uses opto-electronic instruments to carry out
short-distance (shorter than 50 km) terrestrial geometric survey
(triangulation, leveling and astronomic surveying).
Satellite geodesy studies satellite orbits, its motion, perturbations

and satellite based positioning.

Task 3. Answer the questions to the text.

1. What does the term geodesy mean?
2. What does geodesy as a science study?
3. What is the aim of geodesy?
4. How is geodesy classified?

5. What does each branch of geodesy study?

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

1. The science of geodesy includes the study of temporal
variations of the Earth and its gravity field.

2. Geodesy isn’t used to determine space coordinate system.
3. Marine geodesy is used to establish a unified national geodetic
network to meet the needs of topographic mapping.

4. Physical geodesy studies geophysical and geodynamic
properties of the Earth.
5. Terrestrial geodesy studies satellite orbits, its motion,

perturbations and satellite based positioning.
