## How it was made

Built in code from published dimensions and photographs, with no image-to-3D generator and no one else’s mesh. 3D model: built by Space Radar from the dimensions JAXA publishes for GOSAT and from JAXA's illustrations and photographs of the craft (looked at, not used).

built by this project in code (the private tool model-from-images: assemble.py, from a yaml of primitives written by a script, object `satellite-gosat`), from the cited numbers and the pictures under `references`; no image-to-3D model was used, and no published mesh of the craft (JAXA publishes pictures, not a model; NASA's 3D Resources path list, 1 583 paths, read by name on 2026-11-05: none of this craft)

THE TWO PAGES AGREE (eoPortal's 'length 2.0, width 1.8, height 3.7' is JAXA's D 2.0, W 1.8, H 3.7); which side is which is read from the exhibit photographs: the 3.7 m is the launch axis, the 1.8 m the paddle axis, the 2.0 m the Earth-facing depth, the 3.7 m excluding the adapter. NOT CITED, read off the pictures: the split of the body into two boxes at half height, every position on the Earth face, the A-frame trusses (1.0 m), the panel size (3 sections of 1.65 m by 3.2 m a wing, scaled from the stowed paddle's height in the exhibit photographs and the 13.7 m and 6 m: 31.7 m2 and 3.8 kW is about 120 W/m2), the ring (1.24 m across, 0.2 m), the thrusters' places, the antennas' sizes, the TEDA boxes, the cell colour and every other colour.
