摘要：

In describing the INTELSAT IV communications satellite, each subsystem is treated separately. The satellite, which is designed for a 7-year lifetime, weighs 1,410 kg at launch and 730 kg after apogee motor firing. The enitre communications subsystem is on the despun portion of the satellite. Each of two global coverage 6-GHz antennas feeds a pair of redundant 500-MHz-bandwidth receivers. Each of twelve 36-MHz-wide channels is amplified by one of a pair of redundant output TWTs. There are two global transmit antennas and two steerable spot-beam antennas with 4. 5-degree beamwidths. The major part of the satellite (450 kg) spins at a nominal 51 rpm and includes the electric power, despin control, and positioning and orientation subsystems.
