About this model
QPS-SAR 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 13,432 triangles in a 122 kB glTF file, and is 3.6 m across at full scale.
On Space Radar’s live map it is drawn for 12 catalogued objects, each where its published orbit puts it now. Open it on the map.

iQPS's investor presentations (QPS-SAR 1's flight model: bus 0.8 x 0.8 x 0.8 m, antenna 3.6 m by 1.0 m, 100 kg class; 36 leaf springs from unit 3) as quoted by a search extract of 2026-11-07, and eoPortal's QPS-SAR article ('0.8 m in diameter and 0.15 m in height when stowed ... unfolds to a seamless bowl 3.6 m in diameter', 'body-mounted solar panels', on the order of 100 kg)
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 the operator's published sizes; layout read from the operator's photograph and rendition as eoPortal prints them, looked at only.
The full record
built by this project in code (tools/nanosat-builder on the part library of tools/stage-builder/lib.py), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh: NASA's 3D Resources has none of this craft, and no operator of it publishes a model under a free licence (searched 2026-11-07)
Where the map uses it. the 12 QPS-SAR satellites of units 5 and later in the catalogue (NORAD 58578, 59447, 60542, 63205, 64055, 64340, 65116, 66316, 67228, 100243, 100401, 101257); the craft's own shape, not a family stand-in. They wore the procedural mesh-dish radar. forge #174
Licence note. No operator picture or model is in the file. The pictures named under `references` were LOOKED AT ONLY (iQPS's own, copyright iQPS, as eoPortal prints them; they are on no sheet that ships); the shape is this project's, under this repository's licence, built from published numbers (facts). NO LOGO AND NO LETTERING is on the mesh.
