Deep Space
and Satellite Communications

The deep space
channel is characterized by wide signal bandwidth and low signal power. The
noise environment is substantially Gaussian in nature. In this environment
channel capacity increases approximately linearly with SNR.
CCSDS Recommendations
(specifically
CCSDS 131.0-B-1)
The Consultative
Committee for Space Data Systems (CCSDS) is an organization established by
the management of member space agencies to address data systems issues and
to formulate sound technical solutions to these issues. Synchronization and
channel coding issues are dealt with in CCSDS recommendation 131.0-B-1.
The table below shows all our CCSDS compatible devices currently offered as
standard products for sale. Contact us at
