Glad I could help, Thats interesting info about the Sats. I'm a Ham Radio operator and use to work various Ham radio satellites as a hobby some of them Russian. These were orbiting satellites not geosyncro Sats. and we used a fairly sophisicated commuter programthanks Bstar, that's great info. By the way, the company I work for, Space Systems Loral, built the Sirius Radio satellites. I worked on the first 4 satellites (3 of which are on-orbit and the 4th is a ground spare), and we just launched Sirius-5 a few months ago.
