While all Intelsat Epic satellites have been built on the Boeing 702MP platform, the technology on each satellite has evolved and enhancements have been made. For example, Horizons 3e adds a multiport amplifier that optimizes power across the satellite. With earlier Intelsat Epic spacecraft, while the digital payload enabled beam switching, each spot beam was assigned a fixed amount of power. If a spot beam was not in use, the power could not be reallocated to support the spot beams that were in use. With the multiport amplifier, if one spot beam is idle, its allocated power can be distributed to other beams to meet customer throughput demands. By matching satellite power usage to traffic demands, customers can take advantage of the improved efficiency to enhance and expand their operations.
