Satellite models
Thirteen parametric models, the 20 DISCOS shapes, or your own CAD.
The Satellite tab chooses the geometry of the object. Three sources:

| Space stations | ISS | 109 × 73 m, 8 steerable 34 × 11.6 m wings, radiators |
| Tiangong (CSS) | Tianhe, Wentian and Mengtian in a T, Tianzhou and Shenzhou docked, six wings | |
| Rocket bodies | Falcon 9 second stage | Ø 3.66 m, 13 m with the MVac nozzle |
| SL-16 (Zenit-2) | Ø 3.9 m, 11.5 m | |

| Reference | Calibration sphere | 1 m Lambertian sphere |
The GEO, Starlink, Earth-observation and CubeSat models are fully parametric (bus, wings, reflectors, instrument); rocket stages expose diameter, body length and nozzle; the stations and Hubble are fixed geometries.
Choosing a model also sets its default materials, attitude (rocket bodies tumble end over end) and typical range.
