About this model
GLONASS-K 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 4,950 triangles in a 32 kB glTF file, and is 9.2 m across at full scale.
It is part of the map’s library; no object on the live map is drawn with it today.

The original letter was prepared by JSC Information satellite systems Reshetnev Company (formerly NPO PM).'; 'SV GLONASS-K permanently supports 3-axis orientation. The origin of the body-fixed RF coincides with the S/V center of mass. OX axis is pointed by SV radius vector from the Earth center. OY axis lies in Sun-SV-Earth plane and is pointed opposite to the Sun direction. OZ axis forms right-handed RF.

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 (the maker's drawings, via the GLONASS information centre; 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's 3D Resources has none of this craft; the survey of 2026-10-13 found no agency model of it under usable terms); no Roscosmos or ISS Reshetnev picture or model was used; the maker's dimensioned drawings, sent to the IGS by the GLONASS information centre, were READ for their numbers and are NOT reproduced
Where the map uses it. the GLONASS-K (K1) records (`COSMOS nnnn [GLONASS-K]` and `[GLONASS-K1]`), 7 in the live saved data of 2026-10-12: Russia's navigation satellite on the unpressurised Express-1000 bus, by number, and the two whose numbers are placeholders (100460, 100744) by the name's bracket. They wore the procedural box (`navigation-glonass-k`, 1 x 1 x 2 m from a catalogue site), which stays as what is drawn while the file loads. GLONASS-K2 is a larger craft and keeps the family box; public #988
Licence note. This project's own shape, under this repository's licence, built from published numbers (facts): the maker's dimensioned drawings were read and are NOT reproduced. NO FREE PICTURE OF THE CRAFT WAS FOUND: two share-alike photographs of models were looked at only (named under references) and nothing of them is in the file. NO ROSCOSMOS OR RESHETNEV PICTURE WAS USED. NO LOGO AND NO LETTERING is on the mesh.
