About this model
GCOM-C 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 5,744 triangles in a 41 kB glTF file, and is 16 m across at full scale.
On Space Radar’s live map it is drawn for the object with NORAD catalogue number 43065, where its published orbit puts it now. Open it on the map.

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 JAXA's published dimensions (no free picture of the craft).
The full record
built by this project in code (the private tool model-from-images: assemble.py, from a yaml of primitives), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh (NASA's 3D Resources, 1 583 paths read 2026-10-26, and NASA Science's resources have none of this craft; the agency pages were searched, and no agency model of it under usable terms was found); no JAXA picture is in the file: JAXA's illustration and photograph of the craft (eoPortal Figures 1, 2, 7, 14) were looked at only, for the layout
Where the map uses it. NORAD 43065, GCOM-C (SHIKISAI), in the live saved data of 2026-10-12: JAXA's climate imager, a gold bus with the copper-blanketed SGLI module on its Earth end and a paddle of two panels each side. It wore the shape of its class (a box with two wings); public #1103 (the issue says 'one long wing': JAXA's illustration and eoPortal's Figure 13 show two paddles, +Y and -Y)
Licence note. This project's own shape, under this repository's licence, built from published numbers (facts). NO FREE PICTURE OF THE CRAFT WAS FOUND: JAXA's pictures as shown by eoPortal were looked at only (named under references) and nothing of them is in the file. NO LOGO AND NO LETTERING is on the mesh.
