oce (Shizuoka disaster medical headquarters) and an emergency network combining a mobile vehicle earth sta-tion for WINDS with ICT units (MDRU: NTT Network Innovation Laboratories) in the front base type SCU of Kosai City (eld hospital), and provided the internet and call services to operate the wide-area disaster & emergency medical information system (EMIS), operated by DMAT in the case of a wide-scale disaster, and the intergovern-mental disaster prevention information sharing system of the National Research Institute for Earth Science and Disaster Prevention, or to communicate between disaster sites and the disaster countermeasures oce (Fig. 13).Aer nishing the drill, the concerned parties of DMAT acclaimed the availability of NICT’s resilient ICT technol-ogy in terms of ensuring data communications of the satel-lite system, because in the mobile telephone network and the internet network, congestion as well as physical dam-ages due to earthquake motion would certainly arise.We need to further improve the performance including the operation side while announcing the availability of resilient ICT technology resistant to disaster by making public the NICT research and development results through cooperation with DMAT and local governments.4.3Open experiment on the 2016 comprehensive disaster preparation drill of Ehime PrefectureWe sent vehicle earth stations for WINDS to the “2016 comprehensive disaster preparation drill of Ehime Prefecture” implemented at the Uwa athletic park in Seiyo City, Ehime Prefecture, on August 28, Sunday, 2016, and conducted the open experiment for building the emer-gency communication network and the disaster informa-tion transfer using WINDS.e drill, assuming a complex disaster due to an earth-quake and a sediment disaster, was practical training fo-cused on the cooperation of disaster prevention agencies and private cooperative bodies. NICT relayed the rescue operation situations in real time from three places: the Uwa athletic park, the site countermeasure headquarters; the transport site for disaster relief materials; and the Seiyo civilian hospital, a disaster core hospital, to YouTube using WINDS, while providing lines for the “Disaster informa-tion system of Ehime Prefecture (cloud)” (Fig. 14).We received armation from prefectural agencies that the operation of the “Disaster information system of Ehime Prefecture (cloud)” through the communication satellite was possible. In addition, the high-speed internet in the local countermeasure headquarters was assessed to be the last measure if no alternative means exist.FiF14　Image of disaster information transferMobile vehicle earth stationTablet PC for disaster information systemInternetOn-site countermeasure headquartersMonitor (for on-site countermeasure headquarters)TV cameraInitial response activitiesTransport site for disaster relief materialsPrefectural disaster countermeasure headquarters: access to the disaster information system using a PC, etc.Authorities concerned: access to the disaster information system using a smartphone, tablet, etc.Wi-FiWINDSReal-time relay of disaster drill situationDisaster information system of Ehime Prefecture (cloud)Disaster core hospitalKashima Space Technology CenterVehicle earth station for WINDSMobile vehicle earth station3 Ultra-High-Speed Satellite Communication Technology96　　　Journal of the National Institute of Information and Communications Technology Vol. 64 No. 2 (2017)
