The Intelsat IV F-5 was part of the Intelsat IV series which consisted of eight communications satellites, launched from Cape Canaveral during the early 1970s, marked the fifth generation of geostationary communications satellites developed by the Hughes Aircraft Company since 1963 with the launch of Syncom II, the world's first synchronous satellite. The Syncom II was 15 cm high and 28 inches in diameter, weighing 78 pounds in orbit. In contrast, the Intelsat IVs weighed more than £ 1,300 (595 kg) into orbit and were more than 17 feet (5.2 meters) in diameter. All seven satellites exceeded their projected life expectancies and were withdrawn from active duty, the last of which, the Intelsat IV F-1 was retired in October 1987.
The satellite was equipped with 12 C-band transponders. It had 6,000 two-way relay phone calls or broadcast 12 concurrent color television programs or mixed combinations of communications traffic including data and fax.
The satellite had 12 channels of broadband communication. Each channel had a bandwidth of 40 MHz and provided about 500 communication circuits.
Launchedit
The satellite was successfully launched into space on June 13, 1972, at 21:53:04 UTC, by means of an Atlas SLV-3D Centaur-D vehicle from the Cape Canaveral Air Force Station in Florida, United States. It had a launch mass of 1,414 kg.[3]
