The Use of ADS-B Information for Airborne Separation and Collision Avoidance
Jošth Adamová, Eva ; Jonák, Jaroslav (referee) ; Novák, Andrej (referee) ; Vosecký, Slavomír (advisor)
Otázka bezpečnosti všeobecného letectva bola vždy problematická. Nedostatok harmonizovaných technických noriem týkajúcich sa výkonu zariadení umožňujúcich lietadlám všeobecného letectva vidieť a byť videný, sa stal hlavnou prekážkou k ich rozšírenému používaniu v Európe. Rastúca komplexita a hustota leteckej dopravy, a skutočnosť, že sa vzdušný priestor s príchodom nových užívateľov (napr. systémov bezpilotných lietadiel, ktoré zaznamenávajú v posledných rokoch rastúci trend) stále viac naplňuje, zdôrazňujú dôležitosť a potrebu zmeny. Cieľom tejto dizertačnej práce bolo rozpracovať možnosti zlepšenia prevádzkovej bezpečnosti všeobecného letectva v neriadenom vzdušnom priestore, s prihliadnutím na značné výzvy spojené so zavádzaním bezpilotných lietadiel do vzdušného priestoru. S celkovým rámcom ATM prispôsobujúcim sa týmto novým užívateľom vzdušného priestoru, sa ADS-B technológia so svojim potenciálom stáva významným činiteľom. Táto práca skúmala možnosti zlepšenia kooperatívnej “surveillance” v neriadenom vzdušnom priestore (začínajúc od, ale neobmedzujúc sa na ADS-B) a prostredníctvom súboru experimentov hodnotila prijateľnosť, uskutočniteľnosť, a opätovnú použiteľnosť rôznych existujúcich antikolíznych systémov a “situational awareness” systémov, či už šitých na mieru pre všeobecné letectvo alebo nie. Súčasťou výskumu bolo aj skúmanie možného prispôsobenia konceptu “Remain Well Clear” vyvíjaného pre drony, prevádzkovým potrebám všeobecného letectva. Výskumné aktivity v rámci tejto dizertačnej práce prebiehali v dvoch fázach. V rámci prvej fázy, ktorá trvala od roku 2015 do roku 2019, sa uskutočnila séria experimentov. Druhá fáza sa zamerala na prehľadnú analýzu systémov zavedených od posledného experimentu, ktorá vyvrcholila v posledných mesiacoch. Práca zdôrazňuje riešenia, ktoré s vhodnými úpravami majú potenciál byť efektívne prispôsobené na používanie vo všeobecnom letectve.

Collision Avoidance System for Mobile Robot
Dzuro, Daniel ; Hájek, Josef (referee) ; Herman, David (advisor)
This bachelor's thesis deals with the anti-collision system for mobile robot which is often liable to the collisions with other objects. Expensive parts of the robot could be saved thanks to the system. The main issue of the thesis was to design the system of premature reaction and it's application to the existing system which would help prevent the collision on time. Not only the breaking system was used to stop or slow down the vehicle but also the cooperation with the prediction of the vehicle's direction control was needed. Laser rangefinder and ultrasonic sonar were mainly used for this purpose.

Utilizability of civil aircraft anti-collision systems by unmanned aircraft
Batelka, Marek ; Šplíchal, Miroslav (referee) ; Vosecký, Slavomír (advisor)
This thesis explain today and future technologies of air traffic collision avoidance systems and of its utilizability by unmanned aircraft. The first part describes the UAVs and their categorization. Next part deals with the legislative requirements for their operation. The main part deals with TCAS, ADS-B, FLARM and others that are now used in civil aviation as a key technology to avoid a collision. The last part describes the UAV systems with a focus on the actual sensors used in systems for unmanned aerial vehicles for collision avoidance. The whole work deals with issues of development of collision avoidance systems and summarizes the current technology with a view to its possible application in the near future.

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).

Robocar - The Autonomous Driving
Hnát, Miroslav ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
In my Bachelor thesis I deal with automated car driving requirements. First I make the real plan and select the correct software tool for simulation and realization this issues. Second I solve model for autonomous car driving simulation, breaking and rotation wheels. There is open area with several obstacles in simulation conditions. I define possibly errors and I recommend its solution. Next very important part of my thesis are identify the parameters of real vehicle and verification the correctness of model by simulation test. I review variances from model. The object of this has to check reactions of the real system. Whole solution will be implemented into individual components. The individual components will be then compared with simulation results. In conclusion I will appreciate achieved results and recommend my solutions.
