| Abstract(in English) | The Unmanned aircraft system (UAS) has been researched and developed as a temporal communication system for the emergency and rescue service in disaster such as earthquake, serious accidents, and so on. In the typical UAS model, several numbers of unmanned aerial vehicle (UAV) with the velocity of 40 to 100 km/h and the altitude of 150 to 1,000 meters shall be applied to the provision of wide service coverage. The UAV is composed of a transmitter and a receiver so as to transfer the signals from terrestrial stations and terminals. Therefore, Doppler shifts are occurred in the carrier frequency of the transmitted and received signals by a change in line-of-sight velocity between the UAV and the terrestrial terminal. By observing multiple Doppler shift values for different UAVs, it is possible to detect the position of the user who possesses a communication terminal for the UAS service. In order to confirm the practicality of the proposed positioning method, performance evaluation of positioning accuracy for user position detection method using two UAVs have been conducted including control error of UAV navigation and measurement error of Doppler shift. In this study, a position determination method using one UAV by measuring multiple Doppler frequencies at different time is newly proposed and performance evaluations of positioning accuracy are conducted including control error of UAV navigation. From the simulation results, it is confirmed that performance of positioning accuracy would be changed depending on position relation between UAV and user, and an amount of control errors. |
