Experiment Date

November 29, 2014

Experiment Agency

National Disaster Medical Center (DMC)

Location of Experiment

Japan Ground Self-Defense Force Camp Soumagahara (Oaza-Arai, Shintou, Kitagunma District, Gunma Prefecture)

Gunma University Hospital (Showamachi, Maebashi, Gunma Prefecture)

Tsukuba Space Center *Internet Gateway Station

Outline of Experiment

  JAXA and DMC are considering utilization of Kizuna communication line to promptly provide the information exchange environment necessary to emergency medical activities of Disaster Medical Assistance Team (DMAT), such as an emergency response in a stricken area at the outbreak of large-scale disaster with the disconnection of ground communication line.
  AT Kanto Block DMAT training, Kizuna high-speed internet communication line was established in order to promptly provide DMAT dispatch instruction, understanding of the situation, and coordination with the carrying destination of stricken patients. DMAT was in charge of transportation, installation and operation of earth stations as a training.
  Kizuna earth stations were installed at Japan Ground Self-Defense Force Camp Soumagahara and Gunma University Hospital. By Kizuna communication line, the information was gathered, transferred and shared by Emergency Medical Information System (EMIS). And also the air transportation training of the earth station by helicopter was carried out as an effective means in a case where any ground transportation is difficult or it takes a long time to deliver. Kawasaki Heavy Industries built BK1170C-2 helicopter owned by JAXA Institute of Aeronautical Technology was used for this training from Cabinet Office Tachikawa helicopter landing spot to Camp Soumagahara. At this Camp Soumagahara, the operation test of Disaster Relief Aircraft Information Sharing Network (D-NET) was performed using Kizuna communication line.

Experiment Results

◆Kizuna earth station installation and operation training
  The DMAT crews conducted the installation and operation training for VSAT and USAT transported by helicopter at Camp Soumagahara and Gunma University Hospital respectively.
  At each earth station, the installation and communication line establishment could be achieved in a short time by two or three crews.

◆Air transportation by JAXA helicopter
  Portable USAT stored at Disaster Medical Center (DMC) was loaded at Tachikawa helicopter landing spot and transported to Camp Soumagahara.
  The earth station was carried without any trouble according to the loading method for its layout and fixing confirmed in advance. It took 10 minutes for loading and 5 minutes for unloading by DMAT crews.

◆Connection with D-NET
  D-NET aims to enable sharing of necessary disaster information such as positions of disaster relief aircrafts, mission accomplishment situations and so on.
  At this training, information sharing with other disaster corresponding base was effectively achieved by connection to D-NET at Camp Soumagahara, using Kizuna communication line.
