1. OBJECTIVES
- To give students the basic knowledge on spherical
astronomy and astrometry, which will help them understand astronomic phenomena. To give
students the knowledge on astronomic methods of determining geographical coordinates and
azimuth of points on the Earth. To give students the basics of celestial mechanics and the
use of Earth's artificial satellites for the needs of surveying.
2. TOPICS
2.1 Summary of lectures
- Celestial sphere and notions related to it, virtual daily
movement of celestial bodies;
- Coordinate systems in geodetic astronomy, transformation
of coordinate systems;
- Basics of time theory; sidereal time, solar time (world
time) dynamic time, atomic time, coordinate time, time scales, time dissemination;
- Astronomic refraction, parallax, aberration;
- Determination of geographic coordinates of a point on the
Earth with the help of astronomic observations;
- Determination of longitude by observing the sun;
- Determination of latitude by observation the sun;
- Determination of astronomic azimuth;
- Artificial Earth's satellites useful for geodetic
purposes;
- Classification of the methods of satellite geodesy;
- Basics of celestial mechanics, Keppler's law, equations
of movement of artificial Earth's satellites.
2.2 Summary of exercises
- Examples of transformation of coordinate systems,
- Solving the astronomic triangle,
- Relation between mean solar and sidereal time,
transformation,
- Work with a computer program for the simulation of
virtual daily and yearly movement of celestial bodies,
- Data acquisition from astronomic almanacs, interpolation
of values for the given moment of observation.
