Abstract
Vesoljski odpadki so vsi objekti, ki jih je v vesolje poslal človek in ne služijo več svojemu prvotnemu namenu. V vesolju se kopičijo že od leta 1957, ko je bil v vesolje izstreljen prvi umetni satelit. Med vesoljske odpadke štejemo odslužene satelite in njihove nefunkcionalne dele, raketne stopnje, druge ostanke raket, odkrušene delce barv, ostanke goriva, prah in pomožne motorje. Sem spadajo tudi izgubljeni predmeti ter vsi ostali delci, ki so nastali zaradi eksplozij in razpada umetnih objektov ter trkov objektov med seboj. Danes že lahko govorimo o prenasičenosti vesolja z vesoljskimi odpadki, ki jih je toliko, da konstantno trkajo med seboj in s tem nastaja vedno več novih odpadkov. Za nadaljnje misije v vesolje je pomembno, da poznamo območja, kjer se ti odpadki nahajajo, da se jim vesoljska plovila tako lahko izognejo, saj lahko ti resno ogrozijo samo misijo. V mojem diplomskem delu tako najprej temeljito opišem problematiko vesoljskih odpadkov, natančneje njihovo obnašanje ter probleme, ki nastanejo z njihovim kopičenjem. Nadaljujem z opisom metod opazovanja in beleženja, ki so posebej problematične pri majhnih odpadkih ter navedem ostale probleme povezane s tem. Zaključim s pregledom metod odstranjevanja, ki pa so šele v razvoju. Mnogo izmed njih je bilo tudi že preizkušenih, pa vendar še nobena izmed njih ni bila realizirana. Tako danes še vedno obstaja kot edina realna rešitve in možnost za zmanjšanje števila odpadkov v vesolju zmerna in odgovorna raba vesoljskega prostora.

Title:The role of satellite geodesy in monitoring and cataloguing of space debris
Abstract:
Space debris is the collection of objects that were send in the space by the man but no longer serve its initial purpose. They have been accumulating in the space since 1957, when first satellite was launched. More specifically, space debris include defunct satellites and their defunct parts, rocket stages, other parts of the rockets, paint fragments, fuel residues, dust and auxiliary engines. In this category fall also other lost items and all other particles that were incurred as a result of explosions and decomposition of artificial objects and collisions with each other. Nowadays, we have already reached critical density of space debris in the universe; they are constantly colliding, causing the emergence of even more space debris. For the future space missions, it is important, that we know the area, where space debris are located, so that spacecraft can successfully avoid them. Otherwise they can seriously endanger the mission. In my graduation thesis I first present the problem of space debris, more specifically, their behaviour and problems related to their accumulation. Further, I describe methods of observation and data gathering, which are specifically problematic with small debris. I am also addressing other problems related to measurement. I conclude with the methods for removal, which are still in development phase. Some of them were already tested, but none of the methods has yet been realised. Therefore, the sole current solution for the reduction of space debris remains moderate and responsible use of space environment.
