Space Shuttle Antenna Subsystem DesignEllis, H.; Cubley, H. D.; Symonds, Richard J.; Rockwell International; NASA/Lyndon B. Johnson Space Center (International Foundation for Telemetering, 1974-10)The unique nature of the Shuttle orbiter is that all of its systems must meet the design requirements of a spacecraft as well as the basic aircraft requirements for atmospheric flight. The Shuttle antenna system design, therefore, faces many unique problems. Some of the most significant of these problems include the interface with the Shuttle thermal protection system, the wide range of thermal extremes and rates to be encountered, the long life requirement, and the need for lightning protection. In addition, the radiation coverage requirements of some of the Orbiter antennas are complicated by the multiple requirement for operation during launch, from earth orbit to both ground station and relay satellites, and to the landing area during atmospheric flight. The unique engineering problems that result from these requirements will be described along with techniques that are planned for their solution.
