abstract = "The need for a global quick and efficient communication,
observation and understanding of events on Earth and conquest of
space, motivates spacetechnology development. The CubeSat
standard, also known as U-Classnanosatellite platform, has enabled
the flight qualification of innovativespace technologies developed
in academic environment and / or emergingcompanies in the sector.
For over three decades leading research anddevelopment satellites
in Brazil, the National Institute for Space Research(INPE) has
supported over the past five years the development
ofnanosatellites projects in INPE´s regional centers at Northeast
and South of Brazil in cooperation with local universities. In
this context, NanosatC-Brfamily has been developed. First
satellite, NanosatC-Br1, is a 1U Cubesat launched in July 2014 for
purposing of both collecting the Earth's magnetic field data and
measuring in flight the radiation resilience of integrated
circuits designed in Brazil. The qualification of embedded
software systems is one of the main challenges of the second
mission, a 2U Cubesat named NanosatC-Br2 that is planned to be
launched in 2016. The use of existing components on the market
(COTS) added to the standardization of on board subsystems in
nanosatellites platforms have allowed to reduce significantly the
space mission development cycle enabling new space technologies
being qualified on flight at low-cost. However, the verification
and validation activities (V\&V) at different stages of the space
project lifecycle are still required and onerous in terms of
resources and time. At least functional and dependability aspects
of the payload integration with the satellite platform need to be
systemically tested. Aiming to avoid the development of new test
environment every new mission of a nanosatellite family, which
spends time, hardware and software resources, this article
presents a reusable Test System for NanosSatC-BR family. The
reusability issues of Test System are addressed in two
perspectives: (i) reuse the Test System at different stages of the
same mission; (ii) reuse the Test System in different satellites
of the same family. The proposed Test System architecture supports
the V\&V process focusing on interoperability features between
the NanosatC-Br onboard computer and its payloads, aided by fault
injection mechanisms.",
