abstract = "In order to reduce costs on the ground segment for small
satellites projects, Software Defined Radio (SDR) technology is
advantageous as it reduces the amount of hardware components while
adapting for different modulation schemes, link budget
requirements while supporting different satellites. This work
briefly presents this proposal and discusses some of the issues it
entails. The SDR technology uses a processor, a special receiver
and software that plays the main parts of the receiver (mixer,
filters, amplifiers, modulators, demodulators, etc.) to listen to
radio, television and almost all transmission modes, whether
digital or analog. A first trial with this configuration was
implemented to receive signals sent from a Brazilian picosatellite
named Tancredo-1 and obtain the engineering value of the
telemetries sent by the same. For this purpose, specific software
was developed, named UbaTM - Decoder for obtaining the raw value
of each of the telemetries, perform the operations necessary for
the conversion to engineering value and present them friendly on a
screen to the user. A series of support software packages is
presented so that one can pipeline various operations, which can
lead to ground stations automation.",
