## 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; layout read from pictures on eoPortal (Airbus, OneWeb).

built by this project in code (tools/comms-builder, on the part library of tools/stage-builder), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh (neither Airbus nor OneWeb publishes one under terms that allow a derivative)

## Dimensions

- Bus x: 1 m
- Bus y: 1 m
- Bus z: 1.3 m
- Mass: 150 kg
- Array panel width: 1.2 m
- Array panel length: 1.6 m

Gunter's Space Page, https://space.skyrocket.de/doc_sdat/oneweb.htm , OPENED 2026-11-05: 'Arrow bus', Hall thrusters (Fakel SPT-50, later Busek BHT-350), mass 147 kg in its table and 'about 125 kg' in its text. NOT PUBLISHED, OURS (the issue asked that a part with no primary number be left out; the wings are kept because a OneWeb without its wings is not one, and they are ESTIMATED): each wing's single panel 1.2 x 1.6 m with 8 x 11 cells, read off Airbus's render against the 1 m bus, and its 0.85 m boom; the dishes' size (0.38 m); the Ku horn bay's size; which axis of the box is 1.3 m (the Earth axis here); every small part's place
