Notes
Telecom 2A decommissioned and sent to junk orbit October 2005. It had been operating inclined at 3E
Telecom 2B decommissioned and sent to junk orbit July 2004. It had been operating inclined at 47E
1 beyond expected End of Life. Now operating in an inclined orbit, and will be decommissioned if a failure occurs, or when the station keeping fuel runs out.
