AbstractThe unprecedented volume of earth science data generated by NASA's Earth Observing System (EOS) will require significant advancements in the capability and scale of ground-based data acquisition and processing systems. In order to meet this challenge, NASA's Goddard Space Flight Center (GSFC) has initiated the development of key subsystem components for CCSDS front-end processing at 150 Mbps data rates. This effort is a continuation of the Functional Components Approach (1), an approach applied over the last eight years that uses modular, VMEbus subsystems based on Very Large Scale Integration (VLSI) technology to create pipelined, multi-processor telemetry data systems. The result of this development effort is the creation of four new functional component subsystems incorporating four new VLSI Application Specific Integrated Circuits (ASICs) and the augmentation of two existing subsystems to include elements for frame synchronization, Reed- Solomon error correction, CCSDS Service processing, and simulation at EOS data rates. This paper describes this development effort and provides initial functional and performance expectations.
