To prevent confusion: according to the Russian owners of these satellites
Kosmos 2536 is object 44424. Kosmos 2537 and 2538 are the objects
44422 and 44423. These are passive satellites that do not maneuver.

Therefore the Satcat at 18 SPCS and at CelesTrak are not correct.
Jonathan McDowell's GCAT is correct.
