6/ Even reasonably current 18 SDS GP data can be significantly off if it has not detected recent or ongoing maneuvers. Here are the current top ten--all Starlink--that are thousands of kilometers off: celestrak.org/NORAD/elemen....

5/ And if you look at the SupGP vs. GP Comparisons for Starlink: celestrak.org/NORAD/elemen..., reverse-sorted by GP age, you will see the RMS difference for STARLINK-33890 is huge (as expected): 13,099 km. No idea why STARLINK-31318 isn't being tracked. Just one more thing to ponder.

4/ These are 2 more examples of how SupGP data can help. Even large satellites in known orbits can be lost. Satellite operators are encouraged to share their independent tracking data to produce SupGP. Remember, if the 18 SDS GP data is old, so is their SP data. You may be flying blind to others.

3/ For STARLINK-33890, the latest SupGP data is also 0.40 days old: celestrak.org/NORAD/elemen.... Its graph shows it performing stable orbit-raising , as expected: celestrak.org/NORAD/elemen.... It seems to be untracked since orbit-raising began.
