About this model
OneWeb 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 3,492 triangles in a 41 kB glTF file, and is 1.6 m across at full scale.
It is part of the map’s library; no object on the live map is drawn with it today.

Gunter's Space Page, 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 (read 2026-11-05)
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).
The full record
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)
Where the map uses it. every record of klass satellite named ONEWEB: the first-generation Arrow satellites (Airbus OneWeb Satellites, launched 2019 to 2023; 651 in the issue's live feed of 2026-10-11, 25 of them in its table). It was, and while this file is on its way still is, the procedural shape (scene/models.js `oneweb`); public #1001
Licence note. The numbers are facts (eoPortal); the shape is this project's, under this repository's licence. The pictures are LOOKED AT ONLY and nothing of them is in the file. NO LOGO AND NO LETTERING is on the mesh: the operator's mark on the render's radiator panel is a trademark and is not drawn.
