About this model
AstroSat is one of the 203 3D models Space Radar made itself: a space telescope, 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 18,996 triangles in a 118 kB glTF file, and is 8.5 m across at full scale.
On Space Radar’s live map it is drawn for the object with NORAD catalogue number 40930, where its published orbit puts it now. Open it on the map.

ISRO, 'AstroSat - Spacecraft', isro.gov.in/AstroSat-Spacecraft.html, OPENED 2026-11-05: 'Cuboid shaped; 1.96 m x 1.75 m x 1.30 m'; '2 wing assemblies, each having two panels (1.4m x 1.8 m each)'; 'About 1515 kg', '660.2 kg main bus and 854.8 kg of payloads'. eoPortal, 'AstroSat', eoportal.org/satellite-missions/astrosat, OPENED 2026-11-05: SXT telescope length 2465 mm; UVIT Invar tube 1500 mm, primary about 375 mm; CZTI 50 x 50 x 70 cm; three LAXPC; the SSM's three position-sensitive counters. PAGES DISAGREE: ISRO says about 1515 kg, eoPortal about 1650 kg (868 kg of payload), Wikipedia 1513 kg: the mass is not in the mesh. READ: the stated cuboid is the BUS BOX: the stack of instruments stands on its top deck about 1.2 m higher (the SXT's 2465 mm only fits that reading, as the tube runs down through the bus). NOT CITED, read off ISRO's CAD view and photographs: the place and size of every instrument on the deck (the three LAXPC units 0.55 to 0.6 m by 0.5 to 1.1 m and 0.86 m tall, the UVIT tubes 0.5 m across, the SXT tube 0.47 m across, the CZTI slab 0.66 m by 0.9 m, the two SSM plates 0.48 m wide and 0.85 m tall), the arms and booms of the arrays (0.43 m out from the drive, 0.9 m cross-arm, the panels 0.12 m off the face, the hinge gap), the adapter cone and ring (1.14 m across, from the clean-room photographs), the radiator tiles, the thruster pods, the cell grid and every colour.
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 of AstroSat and from ISRO's CAD view and clean-room photographs of it (GODL-India), looked at, not used.
The full record
built by this project in code (the private tool model-from-images: assemble.py, from a yaml of primitives written by a script, object `satellite-astrosat`), from the cited numbers and the pictures under `references`; no image-to-3D model was used, and no published mesh of the craft (ISRO publishes pictures, not a model; NASA's 3D Resources path list, 1 583 paths, read by name on 2026-11-05: none of this craft)
Where the map uses it. NORAD 40930 (ASTROSAT, 2015-052A): ISRO's multiwavelength space observatory, launched on PSLV-C30 on 28 September 2015 into a near-equatorial orbit about 650 km up (6 degrees). It was drawn as the generic telescope tube; public #970
Licence note. None of the pictures is in the file and none was fetched into it. READ AS THE SHAPE IS DRAWN: ISRO's CAD view of the craft and eleven ISRO photographs of it in the clean room, which Wikimedia Commons carries under GODL-India (the Government Open Data License - India: use with credit); eoPortal's page for the instrument sizes (credit ISRO, AstroSat collaboration; no licence stated: numbers only). 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.
