Star Signal Solutions successfully observed three of the six objects deployed from the H3 launch vehicle launched at 09:53:59 JST on June 12, 2026. The observations were conducted from Japan during the 20:00 JST hour on the same day.
For this campaign, Star Signal Solutions applied its proprietary orbit analysis and prediction technology immediately following launch to estimate the trajectories of the deployed objects. Observations were then conducted based on these high-precision predictions.
Through detailed analysis of the acquired optical observations, orbital characteristics, and photometric signatures, the company has made the following preliminary identifications:
- The first detected faint object is highly likely to be STARS-X
- The subsequently observed brighter object is highly likely to be PETREL
- A relatively faint streak-like object detected afterward is estimated to be either BRO-22 or VERTECS
This observation campaign demonstrates the ability to rapidly detect and track newly deployed space objects even when orbital information is limited immediately after launch. By combining proprietary orbit prediction technology with optical observation capabilities, Star Signal Solutions achieved early acquisition of newly deployed objects within hours of launch.
This capability provides a valuable technical foundation for satellite operators seeking early orbit verification and post-deployment situational awareness. It is expected to contribute not only to the safety and reliability of space operations but also to the stable utilization of critical space infrastructure.
Star Signal Solutions will continue to enhance its space domain awareness capabilities through ongoing observations and data analysis, improving object identification accuracy and advancing its ability to monitor and characterize activities in Earth orbit.
