| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | HAPS (High-Altitude Platform Stations), which provide mobile communication services by installing base station equipment on unmanned aerial vehicles (UAVs) flying in the stratosphere at an altitude of 20 km, are being considered worldwide. The HAPS system is expected to realize a mobile network that is not affected by natural disasters, a mobile communication system that covers a super wide area, and a communication platform for IoT (Internet of Things) terminals such as drones and various sensors. The HAPS communication system consists of a service link between HAPS and user terminals and a feeder link for communication with gateway stations and other HAPS on the ground. In the feeder link, the radio equipment is expected to be used not only to link GW stations but also for inter-HAPS communication and backhaul for aircraft. In this paper, as an initial study of the HAPS feeder link system, we report on the prototype development of a millimeter-wave band feeder link experimental radio system that controls the beam direction considering the positional relationship with the target and the attitude change of the HAPS. Furthermore, we report on a long-range millimeter-wave communication experiment conducted at Kujukurihama in Chiba. | |
