The Communication and Data-Handling Subsystem for the Advanced Orbiting Solar Observatory

This paper describes the communications and data-handling subsystem (CDHS) for the Advanced Orbiting Solar Observatory (AOSO). The CDHS is presently being developed by Texas Instruments Incorporated for Republic Aviation. Goddard Space Flight Center is the responsible NASA agency. The paper includes a detailed functional description of the CDHS, a presentation of the packaging design, and a brief description of the engineering model constructed. Several pictures of the engineering model are included to aid in the description of the packaging.
