What Star Signal Solutions does

Star Signal Solutions株式会社 is a JAXA-certified Japanese startup founded in October 2023 that provides space situational awareness (SSA) and space traffic management (STM) infrastructure to satellite operators, space agencies, and defense organizations. The company operates a four-module integrated platform: an observation service using proprietary optical telescopes and image-analysis techniques capable of detecting sub-10 cm debris, an orbit analysis service with dynamic atmospheric density modeling and multi-station orbit determination, a space-object database combining proprietary and public data into high-precision catalogs including uncatalogued small debris, and S-CAN — a collision-avoidance navigation software commercialized from JAXA's RABBIT tool and delivered as SaaS with web API access.

Revenue is generated through subscription/recurring contracts on the observation, orbit analysis, and S-CAN services, supplemented by data monetization on the catalog product. Go-to-market is direct B2B and B2G sales via inquiry-based web forms, government MOUs, and conference-led thought leadership (e.g., Space Debris Conference 2026 in Riyadh). Named government customers include the Philippine Space Agency (PhilSA, active S-CAN user) and Japan's Air Self-Defense Force 1st Space Operations Squadron (trial/evaluation). The company holds MOUs with Look Up Space (France), Inovor Technologies (Australia), PhilSA, JASDF, and the University of Tokyo's Kiso Observatory, and has been selected for the JAXA Space Strategy Fund (JPY ~2 billion over four years) to develop sub-10 cm debris observation technology. As of mid-2026, revenue is not publicly disclosed and the company remains in an early commercial stage.

Core offering

Star Signal Solutions develops space situational awareness (SSA) software and observation services for orbit analysis and collision avoidance. The company delivers an integrated SSA platform comprising four service modules: observation (detecting space objects including sub-10 cm debris via proprietary telescopes), orbit analysis (high-precision trajectory determination and prediction), space object database (cataloging uncatalogued debris), and S-CAN collision avoidance navigation software commercialized from JAXA's RABBIT tool. These are sold primarily to satellite operators and government agencies for end-to-end space traffic management.

Product overview

Star Signal Solutions offers a unified SSA (Space Situational Awareness) platform comprising four integrated service modules: Observation Service (for detecting space objects including sub-10 cm debris), Orbit Analysis Service (for trajectory determination and prediction), Space Object Database (catalog of tracked objects), and S-CAN (Collision Avoidance Navigation for satellite operators). These services work together to provide end-to-end space traffic management from object detection to collision avoidance decision support.
