## 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 and a photograph of a model of Sentinel-5P by SkywalkerPL (CC BY 3.0).

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); ESA's own pictures and models were NOT used: ESA's terms forbid derivative works

The instrument is mounted in a canted position, such that its radiator has an unobstructed field of view.'; 'The nominal operational scenario for the payload instrument will always be nadir-pointing in the instrument imaging mode.'; 'EPS (Electrical Power Subsystem): Three deployable solar arrays (5.4 m2) using GaAs triple-junction solar cells, supply 1500 W of average power.'; 'the 3 Star Tracker Optical Heads'; TROPOMI 'massPowerSize 206.6 kg, plus 17.4 kg for the instrument control unit 170 W (average) 1.4 m x 0.65 m x 0.75 m'; 'Payload thermal control Passive, use of a 1.5 m2 radiator'; 'Observation pointing Fixed nadir pointing'; 'LTAN (Local Time on Ascending Node) = 13.35 hours'; 'The spacecraft is 3-axis stabilized, the design provides an optional yaw steering.' DERIVED: three wings of 1.8 m2, each 1.8 x 1.0 m; their tips 2.8 m from the axis. READ OFF THE PHOTOGRAPH OF A MODEL: the gold hexagonal body; the three wings hinged at the end away from TROPOMI, one on every other face, each with a dark stay; silver patches and a patch of cells on the faces; TROPOMI and a silver trough under the radiator on the far floor, reaching past the body's edge; two white rods. OURS: the body's 1.75 m across and 2.4 m height (inside the cited 3.35 m with TROPOMI and the ring), the wings flat and square to the axis, the radiator's cant, every place on the Earth floor.
