About this model
GOSAT is one of the 203 3D models Space Radar made itself: a satellite, built in code from published dimensions and photographs, with no image-to-3D generator and no one else’s mesh.
Shape built from published dimensions and pictures; details simplified. It has 17,052 triangles in a 133 kB glTF file, and is 14 m across at full scale.
On Space Radar’s live map it is drawn for 3 catalogued objects, each where its published orbit puts it now. Open it on the map.

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.
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).
The full record
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)
Where the map uses it. NORAD 33492 (GOSAT (IBUKI), 2009-002A): JAXA's first greenhouse-gas observing satellite, launched on 23 January 2009. NOT for GOSAT-2 (43672) or GOSAT-GW (64694): later craft on other buses, not built here. It had no route of its own and was drawn as the generic satellite; public #959
Licence note. None of the pictures is in the file and none was fetched into it. LOOKED AT ONLY: JAXA's illustrations on eoPortal (figures 2, 4 and 5 and the header picture, credit JAXA, no licence stated) and four photographs on Wikimedia Commons of JAXA's GOSAT exhibit at the Tsukuba Space Center (CC BY-SA 3.0, CC BY-SA 4.0 and CC0; credits on the file pages). The shape is this project's, under this repository's licence, built from published numbers (facts). NO LOGO AND NO LETTERING is on the mesh.
