In this master thesis examines of the flight distance increasing cases for remotely controlled aircraft. Unmanned aerial vehicles are currently undergoing rapid development, they are widely used not only in the military tasks but also in the civilian sector, but their uses are limited by short control distances affected by natural and environmental conditions and inadequately selected wireless parameters. We are faced with radio transmission issues for the aforementioned reasons. During the investigation analyzes how to increase the flight distance by upgrading the ground control station without changing the parameters of the remotely controlled aircraft. By the research has been developed the algorithm for the maximizing flight distance. With specialized radio frequency planning software, “EDX Signal ProTM”, has been performed experimental measurements which calculates the received signal level and link availability. For the verify of the algorithm operational has been made a real field investigation which calculate the distances between ground control station and remotely controlled aircraft. Experimental studies confirmed the operation of the algorithm. For the verification of the official manufacturer parameters of the remotely controlled aircraft and ground control station parameters have been also checked. After the improvement of the civilian remotely controlled aircraft system, has been established that without additional investment, can be them adapted for military intelligence purposes which does not require large operational capabilities of the aircraft, application systems, additional signal coding algorithms and other security parameters. |
