About this model
COSMO-SkyMed Second Generation 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 12,780 triangles in a 65 kB glTF file, and is 5.7 m across at full scale.
On Space Radar’s live map it is drawn for the object with NORAD catalogue number 44873, where its published orbit puts it now. Open it on the map.

eoPortal, eoportal.org/satellite-missions/cosmo-skymed-second-generation…, OPENED 2026-11-05: the table 'SAR antenna sizes 5.7 m x 1.4 m' (for the second generation and the first); 'The SAR antenna modular design consists of ten identical “macro tiles”'; 'Each spacecraft has a mass of 2230 kg'; 'PRIMA platform: CSG platform is based on the PRIMA concept which foresees three main modules structurally and functionally decoupled'; 'The spacecraft features a 3-axis stabilization system with gyro, sun sensors and STT (Star Tracker), a set of 4 reaction wheels, a CMG (Control Moment Gyro) assembly and 3 torque rods'. NO PAGE GIVES THE BUS OR THE ARRAYS IN METRES, and the page gives no solar-array area. READ OFF TAS-I'S DRAWING BY THE CITED 5.7 m: a bus about 1.9 m square and 3.4 m high; two wings of four panels, 5.6 m by 2.0 m each (a little longer than the antenna), on a frame 1.1 m long. OURS: those numbers, the colour of the antenna's face (bronze, after ESA's render), the ring's size, the frame's shape (five rods and two gussets for what is a plate with a hexagonal hole), the sun sensors, the darker foil band.
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 (eoPortal, ESA) and TAS-I's and ESA's pictures of COSMO-SkyMed Second Generation, looked at for the layout.
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 2026-11-05, has only RADARSAT-1 of the radar craft and none of this one; the survey of 2026-11-05 found no agency model of it under usable terms)
Where the map uses it. NORAD 44873 (CSG-1), 51444 (CSG-2) and 67304 (CSG-3), in the whole active catalogue: ASI's second-generation COSMO-SkyMed satellites (2019 to 2026) on Thales Alenia Space's PRIMA bus, drawn as the generic radar blade; public #980 ('the second-generation bus separately'). NOT the first generation (COSMO-SKYMED 1 to 4): its file `cosmo-skymed` is a smaller craft
Licence note. The shape is this project's, under this repository's licence, built from published numbers (facts); the pictures are the property of the credit holders named on them, were LOOKED AT for the layout, and are NOT in the file or on any sheet this repository keeps. NO LOGO AND NO LETTERING is on the mesh.
