| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Unmanned aircraft systems (UASs) have been researched and developed as temporal communication systems for emergency and rescue services in disasters such as earthquakes and serious accidents. In a typical UAS model, several unmanned aerial vehicles (UAVs) traveling at a velocity of 40–100 km/h and at an altitude of 150–1,000 m will be used to service a wide area. A UAV comprises a transmitter and a receiver to transfer the signals from terrestrial stations and terminals. Therefore, Doppler shifts occur in the carrier frequencies of the transmitted and received signals because of the change in the 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 users that possess a communication terminal for the UAS. In this study, a methodology for position detection is presented based on a least squares method in conjunction with Doppler shift frequencies and a positioning accuracy index, which can be used as an index for position detection accuracy instead of the dilution of precision (DOP) method for a global positioning system (GPS). To confirm the operability and practicality of the proposed positioning method and the positioning accuracy index, computer simulation was conducted by assuming two circularly flying UAVs. The simulation results confirm that parameters such as the flight route, initial position, and velocity of the UAVs would be designed using the proposed positioning accuracy index. |
