International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The international space community, including National Aeronautics and Space
Administration (NASA), European Space Agency (ESA), Japanese National Space
Agency (NASDA) and others, are committed to using the Consultative Committee for
Space Data Systems (CCSDS) recommendations for low earth orbiting satellites. With the
advent of the CCSDS standards and the availability of direct broadcast data from a number
of current and future spacecraft, a large number of users could have access to earth science
data. However, to allow for the largest possible user base, the cost of processing this data
must be as low as possible.
By utilizing Very Large Scale Integration (VLSI) Application-Specific Integrated Circuits
(ASIC), pipelined data processing, and advanced software development technology and
tools, highly integrated CCSDS data processing can be attained in a single desktop system.
This paper describes a prototype desktop system based on the Peripheral Component
Interconnect (PCI) bus that performs CCSDS standard frame synchronization, bit
transition density decoding, Cyclical Redundancy Check (CRC) error checking, Reed-Solomon decoding, data unit sorting, packet extraction, annotation and other CCSDS
service processing. Also discussed is software technology used to increase the flexibility
and usability of the desktop system. The reproduction cost for the system described is less
than 1/8th the current cost of commercially available CCSDS data processing systems.
