Learning outcomes: 1. Knowledge of theoretical foundations of the construction of celestial sphere. 2. Knowledge of the systems of celestial spherical coordinates. 3. Knowledge of the systems for measuring time. 4. Ability to establish the links between the systems of astronomical coordinates. 5. Ability to make the transition between the time measurement systems. 6. Ability to take into account the influence of factors, that to distort the position of the stars on the celestial sphere. 7. Have an idea about the main directions of development and prospects for the practical application of the basic provisions of spherical astronomy to improve the accuracy of geodetic measurements.
