I’m introducing another table showing possible satellites fitting RCA_SIZE values by space-track.org:
| NORAD ID | RCS_SIZE | POSSIBLE OBJECTS | NOTES |
|---|---|---|---|
| 60235 | SMALL | ISTAT-1(1U)(unlikely), GRBBeta(1U)(unlikely), 3CAT-4(1U)(unlikely), Replicator(3U) | - |
| 60236 | SMALL | ISTAT-1(1U)(unlikely), GRBBeta(1U), 3CAT-4(1U), Replicator(3U) | - |
| 60237 | MEDIUM | OOV-CUBE(~6U), CURIE(6U) | Given its position/orbit this could be a small satellite |
| 60238 | SMALL | ISTAT-1(1U), GRBBeta(1U)(unlikely), 3CAT-4(1U), Replicator(3U) | - |
| 60239 | LARGE | ARIANE - UPPER STAGE | Identified |
| 60240 | MEDIUM | OOV-CUBE(~6U), CURIE(6U) | - |
| 60241 | MEDIUM | OOV-CUBE(~6U), CURIE(6U) | Given its position/orbit this could be a small satellite |
| 60242 | MEDIUM | CURIUM ONE(12U) | Identified |
| 60243 | SMALL | ROBUSTA-3A(3U) | Identified |
Here we see something strange, while we expect 5 SMALL objects, we have only 4. To be honest this is the first time I use this value in identification process, so I have no experience why this happens, how accurate are the values and if and how often they change.
For the people here from the missions, please let me know if the sizing described in the table above is right for your mission.
EDIT: I forgot the parameter that the satellites may expand in size during in orbit (deployable antennas/panels etc), so the RCS SIZE expected should not be based on the initial size of the satellite.
