## 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 MDA's drawing and render of RADARSAT-2, looked at for the layout.

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)

## Dimensions

- Bus height: 3.7 m
- Bus diameter: 1.36 m
- Antenna long: 15 m
- Antenna wide: 1.37 m
- Wing long: 3.73 m
- Wing wide: 1.8 m

Source: eoPortal, https://www.eoportal.org/satellite-missions/radarsat-2, OPENED 2026-11-05: 'The S/C bus is based on PRIMA, a reconfigurable bus developed for the Italian Space Agency (ASI) with bus dimensions of 3.7 m (height) by 1.36 m (diameter).'; 'The overall SAR antenna size is 15 m by 1.5 m with a mass exceeding 700 kg.'; 'Aperture size: 15 m x 1.37 m'; 'two solar panels with dimensions: 3.73 m x 1.8 m, each'; 'The SAR antenna itself is supported by ESS, which is used to deploy the antenna and to provide rigid support in the deployed position.'; 'Four thrusters of the propulsion system are in the nadir direction (+Z)'. THE PAGE GIVES TWO ANTENNA WIDTHS, 1.5 m overall and 1.37 m for the aperture: the file draws the aperture's 1.37 m wide radiating face on a 1.5 m wide back (both cited). READ OFF MDA'S DRAWING AND RENDER: that the bus stands on the antenna's back; that both wings lie along the antenna's own axis, each on a triangular white yoke; that each wing is three panels; the stays and the white strips on the antenna's back. OURS: the standoff of the bus above the antenna (0.5 m), the yoke's size and height on the bus, the wing split into three equal panels, the number and places of the stays, the star trackers, thrusters, radiator windows and hold-down fittings (the page names the thrusters, not their places).
