About this model
GEO-KOMPSAT-2B 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 8,484 triangles in a 96 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 45246, where its published orbit puts it now. Open it on the map.

as `gk2a`: the MDPI paper on GK-2A (mdpi.com/2072-4292/13/7/1303, OPENED 2026-10-27) '2.9 x 2.4 x 4.6 (m)' launch, '3.8 x 8.9 x 4.6 (m)' orbit, for the bus both satellites share ('maximum commonality between GK2A and GK2B', eoPortal, GEO-KOMPSAT-2, eoportal.org/satellite-missions/geo-kompsat-2, OPENED 2026-10-27); GK-2B '~3500 kg'; GOCI-II '1.5 m x 1.0 m x 0.9 m' with a 200 mm pupil. OURS: the same bus drawn once more, GEMS's box (1.5 by 1.9 by 1.4 m, a guess from the picture: no number is cited), GOCI-II's box (1.0 by 1.5 by 0.9 m), the two dark gridded panels on the wall (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 45246 (GEO-KOMPSAT-2B) in the live saved data of 2026-10-12: Korea's geostationary ocean and environment satellite (Cheollian-2B): the same gold bus as 2A with GOCI-II and the large pale GEMS box on the Earth end. It wore the generic geostationary bus; public #1118. Not GEO-KOMPSAT-2A (its own file, `gk2a`).
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).
