For some reason, I could not get an English language page to come up for the SiriusSat-1/SiriusSat-2 satellites on the SPUTNIX site, but they do exist, and they have a little more information than the Russian language pages that I translated previously:

http://sputnix.ru/en/satellites-en/siriussat-1-en

http://sputnix.ru/en/satellites-en/siriussat-2-en

Go figure.
