| 50
Mbps CCSDS Processing for NASA Johnson
Numerous System 500 Model
550 Front End Processors are providing ongoing
support of Shuttle communications at NASA
Johnson Space Center’s Consolidated
Communications Facility (CCF). The
CCF was specifically designed to replace
older NASA systems with one easy-to-use
integrated communications system.
To support the CCF, the
Model 550 processors monitor Shuttle information
and route data, video, and voice from space
to ground processing centers for further
analysis. Equipped with special I/O
modules and CCSDS packet processing modules
and algorithms, the processors receive data
streams in various formats, check their
quality, provide the capability for further
processing, and reformat the data streams
for transmission to other destinations.
The new processors also provide an increased
CCSDS bandwidth of 50 Mbps, allowing engineers
to receive and process the wider bandwidth
data to be produced by the International
Space Station.
The Model 550s purchased
for the Consolidated Communications Facility
join 33 other System 500s already at NASA
Johnson supporting such facilities as the
Avionics Electronics Lab, Mission Evaluation
Room, and Orbital Data Reduction Center
where they handle everything from decommutating
frame syncs to performing critical mission
evaluation for Shuttle flights. Together,
these key installations position L-3 Communications
Telemetry-Wast as the leading supplier of
integrated CCSDS, NASCOM, and telemetry
processors for NASA.
