About this model
GEO-KOMPSAT-2A 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 8,370 triangles in a 97 kB glTF file, and is 8.9 m across at full scale.
On Space Radar’s live map it is drawn for the object with NORAD catalogue number 43823, where its published orbit puts it now. Open it on the map.

OURS: the box's 2.4 m north-south, 2.9 m east-west and 4.6 m along the Earth line (the order of the three numbers is our reading), the wing's width 2.8 m, every instrument's size and place, the horns (read 2026-10-27)
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; compared with photographs by the Korea Aerospace Research Institute (KOGL Type 1).
The full record
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 KARI publishes photographs under KOGL Type 1 (attribution) and no model that was found (read 2026-10-27)
Where the map uses it. NORAD 43823 (GEO-KOMPSAT-2A) in the live saved data of 2026-10-12: Korea's geostationary weather satellite (Cheollian-2A): a gold-blanketed box, the Advanced Meteorological Imager and three gold horns on the Earth deck, one wing of two panels at the south. It wore the generic geostationary bus; public #1118. Not GEO-KOMPSAT-2B, which carries other instruments and has its own file (`gk2b`).
Licence note. No KARI picture is in the file. Compared with, with credit: KARI's own photographs of the flight model on Wikimedia Commons (KOGL Type 1: the Korean government's open licence, attribution only), looked at; nothing of them is in the file. The shape is this project's, under this repository's licence, built from published numbers (facts).
