This work focuses on the use of projective geometry methods to determine star positions produced on the basis of positional observations. As is known, projective geometry studies invariant projective transformations. The main feature of projective geometry is the principle of duality, which adds elegant symmetry to many designs. While the properties of the figures that Euclidean geometry deals with are metric, but there are figures that can be converted into one another by movement while maintaining the metric pro...

The article shows that during teaching courses on space geodesy, astronomy, and natural science conceptions at Kazan Federal University (KFU) all the possible modern technologies are used. The natural science conceptions (NSC) course includes a large part on astronomy. This paper describes the modernization of the educational observational base at KFU. The complex of space geodesy and astronomy teaching and the natural science conceptions course at KFU can be contingently divided into four parts: theoretical, prac...

The present work is focusing on construction and analysis of 5 lunar models using space and ground observations. Firstly, it should be noted that the task of building a model of the lunar macro-figure relative to its center of mass and axes of inertia does not have a definitive solution yet. Within the present work the models of the lunar macro-figure are developed on the basis of space and ground observations. The methods of observation had implied binding of lunar objects to stars, i.e. celestial coordinate syst...
