## 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 a picture by Jakubhal (CC BY-SA 4.0).

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 the China Meteorological Administration publishes no model that was found (read 2026-10-27)

## Dimensions

- Diameter: 2.1 m
- Drum height: 1.6 m
- Length: 4.5 m

Source: eoPortal, FY-2, https://www.eoportal.org/satellite-missions/fy-2, OPENED 2026-10-27: 'a diameter of 2.1 m' and the drum 'about 1.6 m (cylinder)'; for FY-2F 'a length of 4.5 m' (FY-2G and -2H 'identical performance parameters as its predecessor'); 'dual spin-stabilized at 100 rpm with a despun antenna platform'; 'Power (280 W) is generated by surface-mounted solar cells'; a 'mechanically despun S-band antenna, and a UHF receive antenna'. Two cited lengths differ (the drum 1.6 m, the whole craft 4.5 m): both are built, the drum 1.6 m and the whole 4.5 m. OURS: the cone (0.55 m), the mast (1.3 m), the belt (0.2 m), the window (0.38 by 0.5 m), the two ribbed antenna cages, the nozzle
