Sceye and SoftBank Corp. have completed the ‘Service Test 1’ (ST1) mission, a ~~13-day~~ record-breaking 30-day trans-Pacific ~~flight covering over 15,000 km~~ stratospheric flight. The unmanned free balloon traveled nearly 30,000 km, launching from New Mexico on August 9, 2026, reaching Japan 13 days later, and returning to ~~Japan.~~ the United States on September 4, 2026. The mission utilized High-Altitude Platform System (HAPS) technology ~~at an altitude of approximately 16.5 km. The test successfully demonstrated~~ to demonstrate several key capabilities, including mobile broadband connectivity to unmodified devices via ~~SceyeCELL technology.~~ SoftBank’s core network. The platform supported voice calls, text messages, video streaming, and emergency alerts. Additionally, the mission verified edge computing capabilities, which reduced latency to 68 ms—a 40% improvement over traditional cloud processing—and confirmed HAPS-based communications with ~~drones.~~ drones to support 3D communications networks. Sceye CEO Mikkel Vestergaard Frandsen stated that the mission proved the company’s technology and operational infrastructure are ready for connectivity services. This successful demonstration serves as a milestone for the commercial deployment of HAPS as stratospheric infrastructure, intended to support 6G, AI, IoT, and disaster recovery communications by complementing terrestrial networks and satellite constellations.
