Aalto HAPS has achieved a crucial milestone by successfully testing its Zephyr HAPS vehicle in Kenya, establishing a 4G mobile connection from high altitudes. In collaboration with Space Compass and NTT Docomo, this test showcases the potential of fixed-wing HAPS technology. The initiative marks the beginning of a dedicated effort to enhance connectivity in Japan, with substantial investments for commercial services planned for 2026.
Aalto HAPS has recently completed a successful test flight of its Zephyr High Altitude Platform Station (HAPS) in Kenya. This connectivity test was conducted for customer Space Compass and its partner NTT Docomo. The test involved connecting a 4G mobile device to the Zephyr HAPS while it flew above 60,000 feet, marking a significant achievement in wireless communication technology, including a call routed from Kenya to the U.K. via local internet infrastructure.
The Zephyr was equipped with a specialized connectivity payload that allowed direct communication with both a mobile device on the ground and a gateway station in Kenya. Aalto’s announcement on March 3 confirmed that this marks the first successful wireless communication test by a fixed-wing HAPS. Various performance assessments, including throughput and signal quality, were also conducted during the test.
Supported by a robust regulatory environment in Kenya, the tests demonstrated the capabilities of the HAPS vehicle, which successfully launched and landed in the region. NTT Docomo, a prominent Japanese mobile operator, along with Space Compass—a consortium involving NTT and SKY Perfect JSAT—are investing $100 million in Aalto to develop HAPS services in Japan by 2026.
Shigehiro Hori, co-CEO of Space Compass, emphasized the importance of HAPS in enhancing Japan’s communication infrastructure, especially in challenging-to-reach areas and during natural disaster responses. He remarked that the demonstration with Aalto’s Zephyr establishes a promising foundation for 2025 as they work towards commercial implementation in the Japanese market.
The successful test flight of the Zephyr HAPS vehicle by Aalto establishes significant advancements in wireless communication technology, facilitating vital connectivity in remote regions. With investments from prominent partners like NTT Docomo and Space Compass, Aalto is poised to revolutionize communication services in Japan by 2026, effectively addressing connectivity challenges in various scenarios.
