ArkEdge Space, a Japanese space startup based in Tokyo that provides comprehensive solutions from planning and design to mass production and operation of micro-satellite constellations, has been selected for the FY2025 “QZSS Utilization Demonstration Project,” jointly organized by the Cabinet Office of Japan and Quasi-Zenith Satellite System Service.

ArkEdge Space will deploy next-generation tide monitoring buoys across island nations in the Asia-Pacific region. Leveraging Multi-GNSS Advanced Orbit and Clock Augmentation for Precise Point Positioning (“MADOCA-PPP”), a high-precision GNSS augmentation service provided by Japan’s Quasi-Zenith Satellite System (QZSS) “Michibiki,” these buoys will collect sea level data and transmit it via the company’s proprietary IoT satellites.

In addition to the design, development, and operation of micro-satellites, ArkEdge Space is focused on the practical integration of communications technologies such as IoT and VDES (VHF Data Exchange System) to enable advanced observation and positioning solutions. Through this demonstration, the company will contribute to addressing challenges in developing regions to disaster preparedness, including tsunami and storm surge monitoring, port infrastructure development, and climate change adaptation.

Field operations are scheduled to begin in November 2025, with plans to host a regional seminar at the Asia-Pacific Regional Space Agency Forum (APRSAF). A separate announcement will be made regarding buoy deployment and project updates. Through this project, ArkEdge Space seeks to contribute to the global adoption of Japan’s satellite positioning technology “Michibiki” and to the advancement of sustainable marine observation infrastructure using IoT-enabled satellite services.
