HEO built a 3D model of XJY-7 from multiple angles and orbits.

CapabilityValue 2.2Oct 27, 2025RT by @insomniacai163: A technology verification satellite spent 5 years in orbit and most relied on a single render to guess its capabilities. HEO analysed XJY-7 with high-frequency Non-Earth Imaging, building a 3D model from multiple angles and orbits. We verified it as a SAR satellite with a large dish antenna and two fixed solar panels that required full-body rotation to charge.

HEO analysed the XJY-7 satellite using high-frequency Non-Earth Imaging.
