Hmm, I also thought about this "problem" of separation. Thats interesting.
My idea was... the sats have to fill different positions, so the upper-stage would fly the same trajectory like the satellites and deploys each of them in single stages.

That's definitely not the case, the DM/Sat separation is known to happen at one specific time,
based on timelines published for earlier Glonass launches. The sats have their own prop and engines to get on station.

Ok, thank you for the explanation. ;-)

Correct. At the moment these 3 satellites are being tested. They will reach their final orbital positions in february only.

Found this in the news today, thought I'd share it with everyone.

Thought this might be of interest; GLONASS-M have been carrying experimental payloads.

All the satellites of №39 block are equipped with additional payload for performing space experiments: satellite №27 is equipped with Li-ion batteries (developer – JSC «Saturn»). A similar experiment with Li-ion batteries is being prepared (JSC «Istochnik»); satellite №28 and №29 is equipped with inter-satellites laser navigation-communication on-board equipment (developer – FSUE «NIIPP»).

Today, Cosmos 2447 was temporarily retired from the GLONASS network because of a perturbation of its signal.
