Isn't n2yo a predictor where you pass 6 kepler elements for every orbiting object and update every month for drag? In that case, IRSO could have updated those when they released the satellites right?


They're updated more frequently when the object is being measured.

I took a look earlier today. The epoch for the TLE of this object was from yesterday, which implies that it's being measured in order for the TLE to have been updated.

And looking again now, I see it was updated again today.


Incredible they have this data for objects the size of a book floating at over 100 miles over our heads.
