Spacecraft

Hot Bird 4 was a geostationary communications spacecraft of the European

consortium. With a constellation of 5 satellites, the Hot Bird family at 13° East formed one of the largest broadcasting systems in the world. By fourth-quarter 1998, the system was delivering over 320 analogue and digital television channels, as well as radio and multimedia services, to more than 70 million homes connected to a cable network or equipped for satellite (direct-to-home) reception. The Hot Bird satellites provided full coverage of Europe and also took in parts of Africa and Asia, including the entire Middle East. In addition to the basic Widebeam and Superbeam, Hot Bird 3 and Hot Bird 4 were equipped with a Steerable Beam which could be oriented anywhere visible from 13° East, either northern or southern hemispheres. Hot Bird 4 and Hot Bird 5 were the first in the world to be equipped with SKYPLEX for on-board multiplexing of digital signals into a single DVB stream which could be received in the downlink by standard IRDs.
