About this model
SVOM is one of the 203 3D models Space Radar made itself: a space telescope, 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 19,144 triangles in a 151 kB glTF file, and is 3.6 m across at full scale.
On Space Radar’s live map it is drawn for the object with NORAD catalogue number 60089, where its published orbit puts it now. Open it on the map.

NOT CITED, READ OFF THE PICTURES AND ESTIMATED, scaled from the 0.54 m mask and the 0.44 m VT: the body (1.35 m along the wing axis by 1.80 m, a platform 0.90 m high and a payload module 0.55 m, 2.35 m with the adapter and the instruments), the place of every instrument on the deck, the sizes of the MXT drum (0.38 m), the VT barrel (0.5 m) and the GRM housings (0.25 m), the adapter ring (1.0 m) and its ribs, the radiator panels, the antennas, and the SOLAR WINGS: three panels of about 0.65 m by 1.15 m each side, 5.5 m tip to tip. NO PAGE OPENED GIVES THE WINGS' SIZE OR THE BODY'S: the wings are the least certain part of the file. (read 2026-11-03)
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 mission papers' published numbers for SVOM and from pictures of it by CNES and the SVOM collaboration (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, object `telescope-svom`), from the cited numbers and the pictures under `references`; no image-to-3D model was used, and no published mesh of the craft (NASA's 3D Resources on GitHub and CNES's pages carry none; the pictures CNES and the SVOM collaboration publish are not free to derive from, so they were looked at only)
Where the map uses it. NORAD 60089 (SVOM, CelesTrak's name, to be confirmed by the lead against the live catalogue): the Sino-French gamma-ray-burst satellite of CNES, CNSA and CAS, launched 22 June 2024 on a Long March 2C from Xichang. It had no route and was drawn as the generic satellite; public #971
Licence note. None of the pictures is in the file and none was fetched into it. LOOKED AT ONLY: CNES/GEKO's illustration (CC BY-SA 3.0, Commons 'SVOM from Target of Opportunity video.jpg'), the illustrations and photographs on svom.eu (credited CNES, IAM CAS, SECM, the SVOM collaboration; no licence stated), the slides of the SVOM consortium's talk (indico.in2p3.fr/event/27290) and a photograph of a prototype ECLAIRs coded mask (CC BY-SA 4.0, Sinucep, Commons). 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.
