About this model
NavIC (IRNSS) 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 6,354 triangles in a 38 kB glTF file, and is 2.1 m across at full scale.
It is part of the map’s library; no object on the live map is drawn with it today.

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 ISRO's published dimensions and drawing of the IRNSS-1 series (ISRO, GODL-India).
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 on GitHub, 1 583 paths read 2026-10-13, has none of this craft; the survey of 2026-10-13 found no agency model of it under usable terms)
Where the map uses it. any record of klass satellite named IRNSS-1A to IRNSS-1I (7 records in the live saved data of 2026-10-12; wings from internal #751): the first generation of India's NavIC on the I-1K bus. They were, and while this file is on its way still are, the family navigation box at Galileo's size. NVS-01 (IRNSS-1J), the second generation on a larger bus, keeps that box; public #990
