## 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: 3 m
- Body y: 3.3 m
- Body z: 5.6 m
- Span: 40.4 m
- Reflector: 2.7 m

Source: GCAT, the 702HP and 702MP satellites mapped here: Length 6.0 to 9.0 m (median 7.0), Diameter 2.0 to 3.5 (median 3.2), Span 33.8 to 48.1 m (median 40). Drawn: a body 3.0 x 3.3 x 5.6 m (7.0 m with the deck antennas), 40.4 m over the wings. OURS (ESTIMATED): the reflectors' 2.7 m and their arms and tilts, the deployed radiators' 1.9 x 3.0 m and their 20 degree lean, the 3.2 m mast, six panels of 2.35 x 2.4 m a wing, the deck antennas.
