Russian Satellite Communications Company operates geostationary
satellites as part of intelsat and eutelsat. Molniya insorfar as I'm
aware still exists and is a constellation of high elliptical orbit
communications satellites  with a 12 hour orbit, it's specifically
useful over the poles.

in one of the photos on the orignal live journal is an inmarsat terminal

the ship is the icebreaker yamal which at 23000 tons is a pretty big
platform to mount hardware on.
