Intelsat 302

  1968-116A


The Intelsat III F-2 satellite was the first of the series to reach orbit, and it replaced Early Bird and Intelsat II F-3 as the prime Atlantic region (AOR) satellite. Initially tested at 35W, it was moved in 1969 to 24W. The satellite had a temperature-related problem with the despin system, and had to be turned upside down every six months to keep the sun shining on the antennas and stop the system from locking up. When the problem first surfaced in June 1969, Early Bird was brought out of retirement and some traffic was rerouted around the world via the Indian and Pacific satellites.
