## 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 the operator's pictures, looked at only.

built by this project in code (release 1.3.0's part library, lib.py and parts.py, kept with the stage's notes in ~/space-radar-handoff/release-1.4/r14-m5/build, one script a craft), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh: NASA's 3D Resources (1 583 paths, read 2026-10-27) has none of this craft, and no operator of it was found to publish a model under a free licence (searched 2026-10-27)

## Dimensions

- Length: 0.84 m

Each microsatellite has a mass of 56 kg'; 'The SV-24 sensor ... with an aperture of 0.24 m'. Launch table: 55 to 60 kg for Global-2 to Global-19; the Gen-3 satellites (Global 31 and 32) are given no size. OURS: the wings (0.80 x 0.50 m, 12 x 6 cells), the barrel's diameter and depth, the dish and its stalk, the hinge arms and braces, the foil's patches, the star tracker
