About this model
RADARSAT Constellation 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 15,032 triangles in a 75 kB glTF file, and is 6.9 m across at full scale.
On Space Radar’s live map it is drawn for the object with NORAD catalogue number 44322, where its published orbit puts it now. Open it on the map.
Dimensions and their sources
| Measure | Value |
|---|---|
| Antenna long | 6.88 m |

| Keep alive wide | 0.5 m |
eoPortal, eoportal.org/satellite-missions/rcm, OPENED 2026-11-05: 'The spacecraft is box-shaped with a single fixed deployable solar panel.'; 'The two-panel spacecraft concept consists of a 6.88 m x 1.375 m SAR antenna.'; 'SAR antenna size 9.45 m2 (1.37 m x 6.88 m)'; the table of the missions' characteristics: 'Solar arrays (each) ... 2.2 m x 1.7 m main power ... 0.5 m x 1.6 m (keep-alive power)'; the drawing's labels: 'SAR Antenna HRMs (12)', 'Launch Vehicle Attach Points (6)', 'AIS Antennas (x4)', 'Thrusters (x4)', 'Thrusters (x2)', 'X-band Antenna', 'SAR Antenna Deployment Subsystem (DSS)'. THE PAGE GIVES TWO ANTENNA SIZES: 6.88 m x 1.375 m (the text and its table of parameters) and 6.75 m x 1.38 m (the table that compares the three RADARSAT missions); the file is built to 6.88 m x 1.375 m. THE BUS IN METRES IS NOT GIVEN FOR THE RCM (the table says only 'Canadian SmallSat Bus'). READ OFF THE DRAWINGS: a bus 1.5 m by 1.45 m and 3.5 m high, because the two 3.44 m halves of the antenna fold flat on its two X faces, and the antenna is 1.375 m wide. OURS: the bus's section and height, the array's lean of 30 degrees and its hinge height, the keep-alive array's place, the strut counts and angles, the antenna's thickness, the foil and the colours.
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 (eoPortal, ESA) and MDA's and the CSA's drawings and photograph of the RCM, looked at for the layout.
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 on GitHub, 1 583 paths read 2026-11-05, has only RADARSAT-1 of the radar craft and none of this one; the survey of 2026-11-05 found no agency model of it under usable terms)
Where the map uses it. NORAD 44322 (RCM-1), 44323 (RCM-3) and 44324 (RCM-2), in the whole active catalogue: the three RADARSAT Constellation Mission satellites (MDA for the CSA, 2019), one design on Magellan's MAC-200 bus, drawn as the generic radar blade; public #981 ('the RCM bus separately'). NOT RADARSAT-2: its file `radarsat-2` is a different, larger craft with two wings
Licence note. The shape is this project's, under this repository's licence, built from published numbers (facts); the pictures are the property of the credit holders named on them, were LOOKED AT for the layout, and are NOT in the file or on any sheet this repository keeps. NO LOGO AND NO LETTERING is on the mesh.
