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.

Visualization and simulation methods of Solar System bodies
Hýroš, Andrej ; Hanák, Jiří (referee) ; Novák, Jiří (advisor)
Táto práca sa zaoberá vývojom programu na simuláciu a vizualizáciu pohybu n telies podľa Newtonových zákonov. Vstupom je zoznam telies a ich počiatočné podmienky. Po dokončení simulácie je vzájomný pohyb telies celého systému animovaný v programe s grafickým užívateľským rozhraním a je uložený súbor s priebehom simulácie. Počas simulácie sú riešené diferenciálne rovnice prvého rádu. V práci boli implementované viaceré algoritmy numerickej integrácie, ktoré umožňujú používateľovi zvoliť si vhodný algoritmus pre potreby jeho simulácie a dosiahnuť tak optimálny priebeh simulácie. Program bol prehlásený ako validný po porovnaní výstupu programu s dátami od NASA.

Calculation of orbit for Solar research satellite
Stopka, Jiří ; Daněk, Vladimír (referee) ; Bartoněk, Jaroslav (advisor)
The aim of this thesis is to propose a suitable methodology for finding orbits around the Earth in which it will be possible to create conditions for a total solar eclipse. The methodology for orbit determination is designed and implemented through a Pascal scripting language, which is included in this work. The resulting orbits obtained using the proposed methodology are mutually evaluated. The thesis also includes a discussion on the scope of applicability of this methodology.

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).
