The orbit plane of Cosmos 2568 is an analogue of those for Cosmos 2551  (49217/2018-081A), Cosmos 2555 (52330/2022-044A) and Cosmos 2560.

All had orbits in the region 280-350 kilometres, near-sun-synchronous inclination and initial LTDN at 11:30. None of them adjusted their orbits at any point and all re-entered within a few weeks.

Cosmos 2568 has matched the 11:30 LTDN:
