International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / The wide use of standard packet telemetry protocols based on the Consultative
Committee for Space Data Systems (CCSDS) recommendations in future space
science missions has created a large demand for low-cost ground CCSDS processing
systems. Some of the National Aeronautics and Space Administration (NASA)
missions using CCSDS telemetry include Small Explorer, Earth Observing System
(EOS), Space Station, and Advanced Composite Explorer. For each mission, ground
telemetry systems are typically used in a variety of applications including spacecraft
development facilities, mission control centers, science data processing sites, tracking
stations, launch support equipment, and compatibility test systems. The future
deployment of EOS spacecraft allowing direct broadcast of data to science users will
further increase demand for such systems.
For the last ten years, the Data Systems Technology Division (DSTD) at NASA
Goddard Space Flight Center (GSFC) has been applying state-of-the-art commercial
Very Large Scale Integration (VLSI) Application Specific Integrated Circuit (ASIC)
technology to further reduce the cost of ground telemetry data systems. As a
continuation of this effort, a new desktop CCSDS processing system is being
prototyped that offers up to 150 Mbps performance at a replication cost of less than
$20K. This system acts as a gateway that captures and processes CCSDS telemetry
streams and delivers them to users over standard commercial network interfaces. This
paper describes the development of this prototype system based on the Peripheral
Component Interconnect (PCI) bus and 0.6 micron complementary metal oxide
semiconductor (CMOS) ASIC technology. The system performs frame
synchronization, bit transition density decoding, cyclic redundancy code (CRC) error
checking, Reed-Solomon decoding, virtual channel sorting/filtering, packet extraction,
and quality annotation and accounting at data rates up to and beyond 150 Mbps.
