About this model
ViaSat-3 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 18,636 triangles in a 120 kB glTF file, and is 44 m across at full scale.
On Space Radar’s live map it is drawn for 3 catalogued objects, each 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 published dimensions (McDowell's GCAT, CC BY; Viasat's own release; no free picture of the craft).
The full record
built by this project in code (the private tool model-from-images: assemble.py, from a yaml of primitives), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh (NASA Science's 3D models and NASA's 3D Resources have none of this craft, and the maker and the operator publish none under terms that allow a derivative); the layout and its sources are under `references` and `dimensions`
Where the map uses it. VIASAT-3 F1, F2 and F3 (56370, 66454, 68893): Boeing's 702MP+ with two eight-panel wings 44 m tip to tip and a large reflector on a boom. They wore the geostationary stand-in `bus-ssl1300`. F1's reflector did not deploy fully in 2023 (Viasat; Gunter); NO FREE PICTURE SHOWS HOW IT LIES, so this file draws every craft as designed; public #1121
Licence note. The numbers are McDowell's GCAT (CC BY 4.0, cited under `dimensions`); the shape is this project's, under this repository's licence. NO FREE PICTURE OF THE CRAFT WAS FOUND: the layout was read off an artist's render on Gunter's Space Page, LOOKED AT ONLY (not fetched by the tool, on no sheet, nothing of it in the file). NO LOGO AND NO LETTERING is on the mesh.
