1970-032A
The F-7 satellite was Atlantic Primary for two years, but failed in 1972. It appears to have been relocated to 3W in mid-1971. The orbit was low after the third stage burn and after apogee firing the altitude was made up with RCS burns. One transponder failed after 22 months in orbit.It seems that the first stage underperformed, but that the launch was still counted a success. D. Baker says that Intelsat quarterly operations reports show it still active to circa 1986.
