Space mission design
Koziel, David ; Navrátil, Jan (referee) ; Zikmund, Pavel (advisor)
In this work, there are basic laws and knowledge relating to space flights into an orbit around the Earth. Also, there are instructions for beginners, who want to work with the GMAT program (General Mission Analysis Tool), which is the program used for designing space missions. In the final part of the work, there is also a use of the program demonstrated on a specific mission of a satellite (CubeSat) into the Geostationary Earth Orbit. In this section, there is a described method of work, individual relevant functions of the program and possibilities, and a way of work in it. Finally, graphical and data outputs of the simulation are evaluated. Therefore, the output of the work is complex characteristics of the basics of problems of space mission design and a brief GMAT software guide, which could be used in the future to teach.

Predictive software for Earth collision with Near Eartch Objects
Stopka, Jiří ; Daněk, Vladimír (referee) ; Bartoněk, Jaroslav (advisor)
Aim of this bachelor’s thesis is to research and discuss the basics of orbital mechanics and their application on a real problem. The application of orbital mechanics is made by creating a software for predicting Earth’s collision with Near-Earth Objects in Borland Delphi 7 development enviroment. The created software should be able to predict close approaches of Earth and Near-Earth Objects in a time scale selected by user and issue a warning in case of a dangerous close approach.

Low Earth orbit trajectory prediction using a machine learning approach
Janda, Přemek ; Vlk, Jan (referee) ; Novák, Jiří (advisor)
Přesné orbitální predikce orbit satelitů na nízé oběžné dráze Země jsou nezbytné pro každodení provádění operací, tak aby se předešlo jejich srážkám. Tato práce se zaměřuje na analýzu histrorických dat trajektorií, tvořených z klacických dráhových elementů. S využitím strojového učení, data jsou sdružena, zpracována a na závěr užita pro predikci dráhy orbity. Nejlepších výsledků předpovědí bylo dosaženo s neuronovou sítí s doulodobou a krátkodobou pamětí (LSTM).
