Status of NASA's multibeam communications technology program
Abstract
Progress with prototype components for demonstrating an acceptable performance level for multibeam 30/20 GHz satellite communications scheduled for service in 1988 is summarized. Numerous companies were contracted by NASA for the various components and subsystems, which include 20 GHz transmitters, a traveling wave tube transmitter, an IMPATT amplifier, a GaAs FET amplifier, a 30 GHz low noise receiver, a trunking matrix switch, and a baseband processor. The key system is a 20 GHz offset dual reflector antenna with shaped surfaces for multibeam transmission. Tests to date have indicated success at meeting the performance objectives.
