The launch took place at 00:45:00 UTC on September 28, 1967, with the spacecraft entering a geosynchronous transfer orbit.
[2] It fired an SVM-1 apogee motor to place itself into its operational geostationary orbit.
The spacecraft was operated at a longitude of 176° east until 1970, before being moved to 166° west.
In total the satellite remained in service for around three and a half years.
[4] As of February 8, 2014 the derelict Intelsat II F-4 was in an orbit with a perigee of 35,742 kilometers (22,209 mi), an apogee of 35,886 kilometers (22,299 mi), inclination of 6.00 degrees and an orbital period of 23.95 hours.
