About this model
INSAT-3D 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 6,368 triangles in a 75 kB glTF file, and is 2.4 m across at full scale.
On Space Radar’s live map it is drawn for the object with NORAD catalogue number 39216, where its published orbit puts it now. Open it on the map.

eoPortal, INSAT-3D, eoportal.org/satellite-missions/insat-3d, OPENED 2026-10-27: '2060 kg (launch mass), 2.4 m x 1.6 m x 1.5 m'; 'The structure is a cuboid with a central cylinder which accommodates two propellant tanks'; one 'deployable solar panel' producing 1164 W; an imager and a sounder with 310 mm telescopes whose 'EO module is mounted external to the spacecraft'; a passive radiant cooler for each; '0.9 m and 1.0 m body-mounted antennas'; a 440 N apogee motor and twelve 22 N thrusters. OURS: which side of the cuboid is which (the 2.4 m east-west, the 1.6 m north-south, the 1.5 m Earth to anti-Earth), the wing's two panels of 2.4 by 1.8 m (read off the CAD drawing's proportions), the coolers' scoops (0.72 by 1.0 m, 0.78 m long), the imager's and the sounder's boxes (read 2026-10-27)
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 eoPortal's published dimensions; compared with pictures by ISRO (GODL-India).
The full record
built by this project in code (release 1.4.0 stage r14-m4: one script a craft on release 1.3.0 W3-b's part library, lib.py and parts.py, kept with the stage's notes in ~/space-radar-handoff/release-1.4/r14-m4/build), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh: a search for one on 2026-10-27 found none, NASA's 3D Resources has none of these craft, and ISRO publishes pictures under GODL-India (reproduction with credit, not altered) and no model that was found (read 2026-10-27)
Where the map uses it. NORAD 39216 (INSAT-3D), 41752 (INSAT-3DR) and 58990 (INSAT-3DS) in the live saved data of 2026-10-12: India's geostationary weather satellites, one design on the I-2K bus: a gold-blanketed cuboid with the imager and the sounder on the Earth face, two white radiative coolers on the north face, two body-mounted dishes and one wing of two panels at the south. They wore the generic geostationary bus; public #1117. Not other INSAT or GSAT craft.
Licence note. No ISRO picture or model is in the file. Compared with, with credit: ISRO's pictures of INSAT-3DR and INSAT-3DS on Wikimedia Commons (GODL-India: reproduction with credit, not altered), looked at only and on no sheet; nothing of them is in the file. The shape is this project's, under this repository's licence, built from published numbers (facts).
