Learning objectives
Introduction to the basic elements of Geodetic astronomy and determination of the coordinates on the Earth's surface using astronomical observations (astronomical coordinates).
Learning outcomes
Relationship between the equatorial and alt-azimuth coordinate system - obtaining geographical coordinates; converting sidereal to mean solar time and vice versa - calculating zonal time; transition from the catalogue coordinates of the celestial body to its apparent position; derivation of basic formulas of classical astrogeodetic methods for determining longitude and latitude.
Content
Application of geodetic astronomy in geodesy; basic equations of spherical trigonometry and solving of spherical triangles; celestial sphere; spherical and rectangular coordinates; coordinate systems (horizontal, equatorial, ecliptic and galactic); parallactic (positional) triangle and coordinate transformation; characteristic positions of the celestial body; time systems and timekeeping; phenomena that apparently change the position of the celestial body (refraction, parallax, aberration of light); precession and nutation; proper motion of stars; Earth's polar motion; astronomical catalogs and yearbooks; basic methods of classical astrogeodetic determination of time and coordinates on the Earth's surface; vertical deflections.
Teaching Methods
Theoretical lectures and computation exercises.
