Abstract (in Japanese) (See Japanese page) 
(in English) The Global Navigation Satellite System (GNSS) has become a powerful tool for determining position worldwide. However, certain location applications, including radio frequency (RF) signal transmitter devices, such as emergency position indicating radio beacons (EPIRB) for search and low-power wide-area (LPWA) IoT devices, do not want to use GNSS owing to its high power consumption. Instead of GNSS, if the device transmits an RF signal, its location can be determined using a low-Earth orbit (LEO) satellite. In this study, we focused on calculating the location of the signal transmitter by receiving the signal at LEO satellites. We simulated the search for the signal transmitter position using the time-difference-of-arrival (TDOA) and frequency-of-arrival (FOA) algorithms. In the TDOA algorithm, we made several simulations using measurements from two satellites, including measurement errors, and obtained the transmitter position with an accuracy of several kilometers in the optimal case. In the FOA algorithms, we performed simulations using measurements from two satellites, including measurement errors, and obtained the transmitter position with an accuracy of several hundred meters in the optimal case. Herein, we present our simulation method and the results.
