About this model
SBIRS GEO is one of the 203 3D models Space Radar made itself: a satellite, built in code from published dimensions and photographs, with no image-to-3D generator and no one else’s mesh.
Shape built from published dimensions and pictures; details simplified. It has 6,344 triangles in a 41 kB glTF file, and is 15 m across at full scale.
It is part of the map’s library; no object on the live map is drawn with it today.

Wikipedia's infobox of USA-230 (SBIRS GEO-1) and USA-282 (SBIRS GEO-4), en.wikipedia.org/wiki/USA-282, read 2026-10-27: 'dimensions = 15 m x 6.7 m x 6.1 m'; bus 'A2100M'; launch mass 4 500 kg. That page does not say which axis is which: 15 m is read as the span over the wings, 6.1 m as the height of the core with its sensor head, and 6.7 m as the depth over the folded radiator doors. The US Space Force's fact sheet (losangeles.spaceforce.mil, 'Space Based Infrared System (SBIRS)') says, as quoted by a search engine on 2026-10-27, 'two sensors; a scanner and a step-starer' on a 'militarized, radiation-hardened' A2100. Shapes (a tall box of silver blanket, a round sensor head on the Earth face, two wings of two panels on long yokes, two radiator doors, a small dish on a boom, an open bay with a white tank on one face) are read off the Air Force's released art (Commons: 'SBIRS-GEO 2.jpg', 'SBIRS-GEO.jpg', public domain) and looked at in Lockheed Martin's SBIRS product card (lockheedmartin.com/content/dam/lockheed-martin/space/photo/sbirs…).pdf, a Lockheed picture, looked at only, nothing of it is used). The sensor's inside is NOT PUBLIC and is not drawn: the head is a closed round housing with a dark aperture and a pointing baffle, as the art draws it.
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 public US Air Force art and published numbers (public domain sources).
The full record
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 and no agency model of it was found on 2026-10-27). ONLY PUBLIC, OFFICIALLY RELEASED PICTURES AND NUMBERS WERE USED: nothing beyond what the US Air Force, Space Force, Navy or the maker has released is drawn, and where a page does not say (the inside of a sensor, a payload's layout, the size of a part) the part is a plain closed shape or is left out, and the row says which.
Where the map uses it. the six SBIRS GEO records (`SBIRS GEO-1 (USA 230)` to `SBIRS GEO-6 (USA 336)`, 6 in the live saved data of 2026-10-12), by number: the Space Force's missile-warning satellites on the militarised A2100M bus. They wore the generic satellite; public #1099
Licence note. Public domain for the pictures read off (works of the US federal government, the Commons API's LicenseShortName, read 2026-10-27); the shape is this project's, under this repository's licence, built from published numbers (facts). NO LOGO AND NO LETTERING is on the mesh. NO MAKER'S PRESS-KIT PICTURE WAS COPIED OR PROJECTED: where one was looked at (named in `dimensions.source`) it is said so there.
