abstract = "The CBERS program is a unique partnership between Brazil and China
in the space technical and scientific sector for the primary
remote sensing data generation technology, this partnership
agreement involves the National Institute for Space Research
(INPE) and China Academy of Space Technology (CAST). The program
is a family of remote sensing satellites CBERS (CBERS-1 and 2,
CBERS-3 and 4) that brought significant scientific advances to
Brazil. The INPE, using only the CBERS-4, has distributed for free
over the internet, approximately 90,000 images. Their images are
used in important fields such as controlling deforestation and
burning in the Amazon, the monitoring of water resources,
agriculture, urban growth, land use and education. It is also
critical for large strategic national projects such as Measurement
of Deforestation by Remote Sensing (PRODES) and Brazilian
Real-Time Deforestation Detection (DETER). The next satellite,
CBERS-4A, is due to be concluded in 2019, its will be placed in a
sun-synchronous Low Earth Orbit. Their optical payloads will be
operated in the visible spectrum with resolutions in the range of
2 to 60 meters. As in previous missions, the Ground Segment is
responsible for tracking and controlling of the satellites CBERS
during the routine phase, including the orbit adjustment maneuvers
to maintain the proper phase, that are made by Brazil, and by
China, in alternating periods. In Brazil, the Ground Segment is
comprised by the Satellite Control Center (SCC) - located in Sao
Jos´e dos Campos, the TT\&C Ground Stations of Cuiab´a and
Alcantara, the Mission Control Center, the Data Processing Center
and the End User. The Ground Segment has more and more served as
cross support and interoperability to space agencies, which
requires an appropriate architecture to support them. The
architecture proposal is based on Dynamic Management of the Space
Link Extension (SLE) Protocol Services. These services are
recommendations of the Consultative Committee for Space Data
Systems (CCSDS) for cross support and have been adopted by several
space agencies, for example: CNES, ESA, JAXA, NASA and INPE. This
paper presents an overview of the CBERS Program, its science
objectives and the CBERS-4A satellites ground segment. It will
then describe a proposal for implementation an Architecture for
Dynamic Management of the Space Link Extension Protocol Services
to be applied as part of the Ground Segment at INPE. The designs
status, the possible contributions for a reduction the cost of
space missions and limitations are also presented.",
