UAV Communication System and its Protection from Jamming

U ovom radu prikazat će se najbitnije o bespilotnim letjelicama. Dotaknut će se njihova povijest, razvoj, a naposljetku i namjene. Objasnit će se kako funkcionira sustav komunikacije navođenih i autonomnih letjelica te obraditi komunikacijski sustavi koji se upotrebljavaju. Pojasnit će se postupci koji se izvode za ometanje upravljanja i komunikacije s bespilotnom letjelicom te istaknuti načini suprotstavljanja istome.In this work we are going to discuss about what are most important facts and terms of Unmanned Aerial Vehicles. We are going to talk about their history and development through years and their purpose in modern world. We are going to explain how does the communication system works at controlled and auto guided UAVs, and also explain and talk about which communication systems are currently in use. We are going to talk about the procedures which are taken in need of defending against UAV and speak about countermeasurments of UAV
