                         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.",
