Orbital elements based on amateur observations | Sun-synchronous Satellites by LTDN - Russia
This a list of satellites in sun-synchronous orbit operated by Russia ordered by LTDN - Local Time at the Descending Node. Names are not necessarily those by which they are known in the NORAD catalogue used by SpaceTrack.
It is notable that the Russian sun-synchronous fleet is quite small. None of the active satellites appearing here date from the Soviet era.
The list is a snapshot and is updated daily. The measure that results in an entry in this table is that the drift rate of LTDN (Local Time at the Descending Node) is no more than twenty four minutes each year. Some satellites may have higher drift rates but they may still be acceptable to their owners/operators. They do not appear here. On the converse, although a satellite is in a sun-synchronous orbit, it is not necessarily active.

For the satellites that do not have formal published elements, thanks go to the radio and visual amateur satellite trackers for their observing, and particularly to Mike McCants for archiving the derived orbits.
