About this model
MTG-S 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 7,128 triangles in a 70 kB glTF file, and is 5.2 m across at full scale.
On Space Radar’s live map it is drawn for the object with NORAD catalogue number 64723, 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 ESA's and eoPortal's published dimensions; compared with pictures by ESA (CC BY-SA 3.0 IGO) and Neq00 (CC BY-SA 4.0).
The full record
built by this project in code (release 1.4.0 stage r14-m4: one script a craft on release 1.3.0 W3-b's part library, lib.py and parts.py, kept with the stage's notes in ~/space-radar-handoff/release-1.4/r14-m4/build), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh: a search for one on 2026-10-27 found none, NASA's 3D Resources has none of these craft, and EUMETSAT publishes no model of its satellites that was found, and ESA's multimedia terms (the ESA Standard Licence) allow use for information and education, not an altered model (read 2026-10-27)
Where the map uses it. NORAD 64723 (MTG-S1) in the live saved data of 2026-10-12: the sounder satellite of Meteosat Third Generation: the Infrared Sounder's white box and baffle and the UVN (Sentinel-4) spectrometer on the Earth end, the same bus and wings as the imager. It wore the shape of the geostationary bus; public #1115. Not the imager satellites (their own file, `mtg-i`).
Licence note. No ESA or EUMETSAT picture or model is in the file. Compared with, with credit: ESA's renders (CC BY-SA 3.0 IGO) and a museum model at EUMETSAT by Neq00 (CC BY-SA 4.0), on Wikimedia Commons; nothing of them is in the file. The shape is this project's, under this repository's licence, built from published numbers (facts).
