SKY Perfect JSAT Corporation (Head Office: Minato-ku, Tokyo; Representative Director, President & Chief Executive Officer: Eiichi Yonekura; “SKY Perfect JSAT”) announces that it will begin providing observation data from the advanced radar satellite “DAICHI-4” (“ALOS-4”), operated by the Japan Aerospace Exploration Agency (Head Office: Chofu, Tokyo; President: Hiroshi Yamakawa; “JAXA”), from late July.

SKY Perfect JSAT will not only provide observation data from ALOS-4 directly to end users but also integrate it into its infrastructure monitoring service “LIANA” (Land-deformation and Infrastructure ANAlysis), which is currently being expanded in collaboration with partners. LIANA utilizes earth observation satellite data to monitor ground deformation of slopes and infrastructure from space with millimeter- to centimeter-level precision. By leveraging the high-frequency, high-accuracy observation capabilities of ALOS-4, the service will enable even more precise analysis and faster detection of ground movement than ever before. In addition, SKY Perfect JSAT plans to renew its service offerings to further enhance usability and accessibility for customers.

Through advanced space technologies, SKY Perfect JSAT is committed to addressing social challenges and helping build a safer, more resilient society by advancing disaster prevention and mitigation, as well as accelerating digital transformation in infrastructure management.
