## 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 published dimensions (McDowell's GCAT, Wikipedia, the makers' figures); layout read from the makers' renders, looked at only.

built by this project in code (tools/bus-builder, release 2.0.0 batch m4-buses) from published sizes, with the maker's renders and the photographs under `references` LOOKED AT ONLY; no image-to-3D model was used and no published mesh (NASA 3D Resources has none of this bus; scripts/check-model-sources.py, 2026-11-07)

## Dimensions

- Body x: 2.4 m
- Body y: 2.9 m
- Body z: 4.8 m
- Span: 39.2 m
- Reflector: 2.6 m

Source: MEASAT-3B 6.6 x 2.8 x 2.3 m stowed and 39.4 m span (Wikipedia, read 2026-11-07); Intelsat 10-02 7.5 x 2.9 x 2.4 m (Wikipedia infobox); Eutelsat 70B 7 m high and 8 m wide over its antennas (Wikipedia); GCAT's 48 mapped satellites, median span 39 m (30 to 47). Drawn: a body 2.4 x 2.9 x 4.8 m (6.9 m with the deck tower), 39.2 m over the wings, 8.7 m over the reflectors. OURS (ESTIMATED): the reflectors' 2.9 and 2.7 m (the renders draw them nearly the wall's height, larger than Eutelsat 70B's 8 m width alone gives) and their places and tilts, the deck reflector's 1.6 m, four panels of 3.9 x 2.5 m a wing, the 2.8 m yoke, the horn and feed clusters, the radiator tile pattern.
