Summary:
The volume of aeronautical communication will increase if the number of aircraft increases further in the future. Therefore, development of technical standards has already begun for future mobile aeronautical communication system using 5091--5150 MHz bands in the aeronautical standards in the United States and the Europe. The data communication protocol in the technical standards of the high-speed aeronautical communications system will use the technique of MIMO (Multiple-Input Multiple-Output) antenna system. Therefore, we have to estimate the characteristics to install MIMO antenna system in comparison to SISO (Single-Input Single-Output) antenna system. It costs so much to execute the trial using actual aircraft because of the operating cost and workload on the coordination for permission of the flight test. For the development of preliminary experimental system with low-operating cost, we made some experiments based on the Unmanned Aerial Vehicle (UAV), such as radio-controlled model aircraft, equipped with the wireless communication system used in the continental area. This paper describes aeronautical radio communication system for Unmanned Aircraft System (UAS). UAS consists of UAV and ground systems. We introduce flight experiments for evaluation of the benefit to install MIMO for aeronautical communication as shown in some experiments and analysis.
