JSAT - ZENRIN - NIPPON KOEI A new business partnership to provide"Satellite Anti-Disaster Information Service"

Oct 15, 2020

  SKY Perfect JSAT Corporation (Head Office: Minato-ku, Tokyo, Representative Director, President & CEO: Eiichi Yonekura, “JSAT”), Zenrin Co., Ltd. (Head Office: Kitakyushu-shi, Fukuoka Prefecture, President & CEO: Zenshi Takayama,  “Zenrin”) and Nippon Koei Co., Ltd. (Head Office: Chiyoda-ku, Tokyo, Representative Director and President: Ryuichi Arimoto, “Nippon Koei”) announced their entry into a business partnership to develop and provide Satellite Anti-Disaster Management Service, the first ever service of its kind in Japan.*1 This service uses and combines expertise from the three companies, JSAT’s satellite data, Zenrin’s map data and Nippon Koei’s disaster prevention technology. Expected to be available in 2021, the service will assess risk, mitigate damage and facilitate rapid recovery from natural disasters such as floods, landslides, earthquakes, volcanic eruptions and other emergencies.

   JSAT and Nippon Koei entered into a business agreement in November 2019*2, to develop disaster management solutions using satellite data to promote disaster preparedness and mitigation projects by monitoring infrastructure in normal times. Now that Zenrin has joined the partnership, its expertise in detailed and precise mapping data will combine with the existing disaster management solutions. By analyzing the incorporated data, this new solution will make it possible to produce a more highly accurate risk assessment and better focus post-disaster analysis for areas and facilities managed by the public and private sector throughout Japan. This is the first service in Japan that reaches down to the individual building level.

  In normal times, the Satellite Anti-Disaster Information Service will use satellite data to visualize disaster risks which will help in disaster preparedness by continuously monitoring a wide area that includes infrastructure such as that on hillsides, river embankment structures and roadways. In the event of a disaster, satellite data will be used to quickly assess damage over a broad area to support rescue and recovery activities and prevent secondary disasters.

  For addressing the problem of flooding, in addition to satellite data for flood detection technology, the service now will have flood prediction technology that uses meteorological/topographical data and SNS-based flooded area mapping technology. This will help to speed up alert issuance and greatly benefit evacuation efforts.

 This service will also be introduced to Asia and other overseas locations. We believe our experience in Japan has made us well positioned to lead in the development of the disaster management field. For this reason, we commit to doing our part to achieve several goals set by the United Nations as Sustainable Development Goals (SDGs) which apply to our industry, Goal 9, “Industry innovation and infrastructure", Goal 11,"Sustainable cities and communities", and Goal 17, “Partnerships for the goals"

  To respond to the increasing risk of disaster in recent years, the Satellite Anti-Disaster Information Service will be useful for business continuity planning (BCP) for both the private and public sectors, allowing precise management of risk during normal times and accurate evaluation of the damage situation when disasters occur. The three companies, leaders in Japan in their business fields of satellites, mapping information, and engineering consulting are teaming up to build and provide this service to aid disaster management so that the world will be safer and more secure.

How the system works

Features of Satellite Anti-Disaster Information Service
  When disaster occurs, this service uses more than 170 small optical Earth Observation (EO) satellites*3 and multiple Synthetic Aperture Radar (SAR) satellites.*4 Small optical EO satellites are capable of timely monitoring of a vast area where multiple damage occurs simultaneously in various locations. SAR satellites, unlike planes or helicopters, can capture images when the weather is bad or during the hours of darkness. By combining two types of satellite, the service facilitates more rapid assessment of damage than had been previously possible and makes it easier to calculate further risk including extent of flooding and potential landslide damage. 
  In normal times, SAR satellites can be used to detect minute deformations as they constantly track infrastructure status and natural physical conditions. This service can improve the customer’s disaster preparedness by providing information that estimates risk and issues alerts.

*1 Confirmed by the three companies
*2 Nippon Koei and JSAT entered into a business partnership using satellite data to determine the risk of accidents due to aging infrastructure. - Service for making disaster 
     prevention and reduction work more efficiently started in 2020.

*3 A satellite that relies on light from the Sun to capture images as with ordinary photographs. The SAR satellite imagery can be obtained in full color and is easy to
*4 One of the Earth Observation technologies used by satellites, known as a synthetic aperture radar satellite. By emitting radio waves from SAR satellites and analyzing the
     reflected pulse from an object on Earth’s surface, it is possible to make observations even in cloudy weather and at night. By repeating the transmission and reception of 
     radar waves while the satellite is moving and then synthesizing them, the large synthetic antenna aperture (the antenna diameter) is created. This technology can capture
resolution images and cover an area with greater accuracy.
