Outline
It is well known that critical infrastructure is often destroyed during large-scale disasters. During the Great East Japan Earthquake, the Disaster Administration Wireless System relay stations, essential for issuing evacuation instructions, became nonfunctional, rendering hundreds of its subsidiary stations unable to receive evacuation orders. The use of the Quasi-Zenith Satellite System (QZSS), Japan's satellite positioning system, for its message service is expected to serve as the final communication network during the acute phase of a disaster. Japan and Europe jointly developed a satellite-mounted message format for broadcasting text messages during disasters via satellite positioning systems, which was released globally this March. In this session, we will introduce demonstration experiments utilizing the QZSS message service as a fallback to the Disaster Administration Wireless System, accompanied by recorded video footage.
