What Space Compass does

Space Compass Corporation (株式会社Space Compass) is a Japanese joint venture founded on July 20, 2022 and owned 50/50 by NTT and Sky Perfect JSAT. The company operates two business units built around space-based communications infrastructure. The Space Data Center Business (宇宙データセンタ事業) provides high-capacity optical data relay services transmitting Earth observation data from LEO satellites to ground stations via GEO satellites at over 1 Gbps, complemented by on-orbit AI processing demonstrated in partnership with Microsoft using Azure Orbital Space SDK to achieve over 98% data transmission reduction through ship-detection applications. The Space RAN Business (宇宙RAN事業) uses High-Altitude Platform Stations (HAPS) operating at 16-18 km altitude to deliver low-latency 5G/Beyond-5G connectivity for maritime domain awareness, disaster communications, and mobile network coverage extension. These units together form the company's "Space Integrated Computing Network" vision integrating GEO, LEO, and HAPS layers.

Space Compass serves institutional and government customers including JAXA, Japan's Ministry of Defense, Microsoft, Airbus Defence and Space, and commercial satellite operators, Earth observation companies, and mobile network operators. The company operates an enterprise sales model with contract-based engagements targeting large infrastructure contracts; specific pricing is not publicly disclosed. Both business lines are positioned as subscription/recurring revenue streams.

The company is in early commercialization, with its first GEO optical data relay satellite (SC-A) under procurement contract with Swissto12 on the HummingSat platform and scheduled for delivery by end of Japanese fiscal year 2029. Space Compass has been selected as the implementing organization for JAXA's Space Strategy Fund Phase II with a support ceiling of 23.5 billion yen over December 2025 to March 2031. The company's registered capital is 187.2 billion yen including capital reserves. Additional MOUs with ESA, Airbus Defence and Space, Hellas Sat, Apolink, JSAT International, and Airspan Networks support technology development, cross-border interoperability, and product-line expansion into stratospheric 5G Air-to-Ground communications.

Core offering

Space Compass develops and operates a Space Integrated Computing Network combining GEO-based optical data relay services for Earth observation satellites with HAPS (High Altitude Platform Station) stratospheric communications for Beyond-5G/6G connectivity. The company also provides on-orbit AI/edge computing for satellite imagery processing, achieving over 98% data transmission reduction. Its first dedicated asset is the GEO Optical Data Relay Satellite (SC-A), being built by Swissto12 on the HummingSat platform with delivery targeted for end-March 2029.

Product overview

Space Compass operates as a dual-business company offering space-based infrastructure services. The first business unit, the Space Data Center Business, combines optical data relay services with space-based edge computing to transmit and process large volumes of satellite-collected data in near-real-time from GEO orbit. The second unit, the Space RAN Business, uses HAPS aircraft in the stratosphere (16-18 km) to provide 5G connectivity for maritime surveillance, disaster response, and coverage extension. These two businesses collectively form the company's 'Space Integrated Computing Network' vision, integrating ground, air, and space communication networks. The GEO Optical Data Relay Satellite (SC-A), Space Compass's first dedicated satellite built on the HummingSat platform by Swissto12, serves as the foundational infrastructure for the optical data relay service, enabling GEO-based high-capacity data relay for LEO observation satellites. Capitalized at 187.2 billion yen, Space Compass is a joint venture between NTT and Sky Perfect JSAT.
