Still no orbit change for Kosmos-2483, clearly dead.
Rokot to resume launches:

According to this report, one of the satellites was lost due to a problem with Briz KM. So do we have a launch failure here, a problem that cropped up during final spacecraft separation?

I have heard partial failure since two of the three separated nominally and burned to their final orbits. Briz-KM on this mission failed to perform CCAM maneuver and de orbit. TEL for Briz-KM was lost early if I remember correctly. I think it is mentioned by anik above.

A partial mission failure due to the one dead satellite, yes, but was that caused by a problem with the launch vehicle itself? The Briz KM stage seems to have inserted the satellite into the proper orbit, which would usually be considered a launch vehicle success regardless of the subsequent deorbit burn issue, but then both the satellite and the stage stopped working. Did they collide? Was there a problem during spacecraft separation? Etc.

Need some one who can read russian to verify if they are saying that all 3 are in nominal operation......?
Says that the three sats were not in the intended orbit but only close to it..

However according to a senior official of detachment B of the VKO staff, the satellites functioning is not affected "One satellite, which incorrectly was said to be lost, after insertion and had to be put on station (?), the two others - separated in different directions.
.Now they are all operating nominally in the interests of the GRU". The booster contractor Khrunichev ... corrected deficiencies in the control system.

Very interesting - so maybe bad attitude control in the last seconds of the burn and the deployment sequence messed up. Also interesting for the explicit statement that the payloads are for the GRU главного разведуправления

So .... how did this one end up, three live satellites in slightly off-nominal orbits, or two live sats and one dead sat?
