abstract = "Amazonia-1 is the first Remote Sensing Satellite entirely
developed at Brazil by National Institute for Space Research
(INPE) and it is expected to be concluded in 2018. Amazonia-1 is a
polar orbit satellite that will generate images with a 5 days
revisit period. To do this, has a wide sight optical imager,
called Wide Field Imager (WFI), able to observe a range of 700 km
with 70 meters of spatial resolution. Its rapid revisit feature
will enable Amazon deforestation alert data to improve in real
time by maximizing the acquisition of useful images in the face of
cloud cover in the region. The Amazonia-1 will also provide
frequent images of Brazilian areas, and may be useful in other
environmental monitoring applications, such as the coastal zone,
water reservoirs, forests of other biomes and natural disasters.
The Amazonia-1 satellite is based on the Multi-Mission Platform
(MMP), which was also developed by INPE and other Brazilian
industries as a part of the National Program of Space Activities
(PNAE), coordinated by the Brazilian Space Agency (AEB). The MMP
is generic platform to 500 kg class satellites. With 250 kg mass,
it provides the necessary resources, in terms of power, control,
communication and others to operate, in orbit, a payload of up to
280 kg. The requirement of high rate of revisits and the need of
controlling and data reception of other remote sensing satellites
available in Brazil, for example, the CBERS (26 days to revisit)
impose new challenges for the ground segment, related to control
system of orbit and attitude and consequently in the reception,
processing and distribution of data through the ground segment
using the Space Link Extension (SLE) Protocol Services. The SLE
protocol services establish activities, based on the Consultative
Committee for Space Data Systems (CCSDS) for cross support
recommendations, including Management Services for Data Transfer
and SLE protocol services related to Telemetry and Telecommand.
These services standards have been adopted by the different space
agencies, such as: ESA, NASA, CNES, DLR, ASI, JAXA, INPE, to
performing tracking and controlling of the spacecrafts. This paper
presents an overview of the Amazonia-1 satellites ground segment,
its objectives, the satellite design based in the Multi-Mission
Platform (MMP) and also the preparation of the ground segment for
the operation with the SLE Protocol and allow for efficient
operations with cross support.",
