             abstract = "Pico and nanosatellites environmental testing are usually 
                         outsourced, and they can be very expensive for some academic 
                         institutions. Thermal-vacuum tests usually comprehend an important 
                         amount of such costs. An in-house development of a thermal-vacuum 
                         chamber has great potential to lower these costs, and also 
                         diversify the educational project research scope. The objective of 
                         this paper is to describe the Systems engineering methodology used 
                         to develop a thermal-vacuum chamber to be used for environmental 
                         testing pico and nanosatellites. The conventional operational 
                         requirements of various state-of-the-art commercial chambers 
                         (found in different laboratories and research institutions) are 
                         described considering their morphology, type of manufacturing, 
                         structure materials, supplies necessary for its operation, 
                         internal and external interfaces, data acquisition systems, 
                         pumping systems (low, medium, high and ultra vacuum), ways and 
                         means of heat transfer, temperature ranges, operating pressure and 
                         general operation and monitoring requirements. The study allowed 
                         the definition and classification of operation, states, modes, 
                         passive and active operations and control and monitoring 
                         philosophy of the analyzed chambers. The work also considered the 
                         general pico and nanosatellite thermal-vacuum testing requirements 
                         to develop the chamber specification. The study showed that the 
                         design of a small thermal-vacuum chamber is feasible and very 
                         promising. Using an in-house chamber tends to reduce overall 
                         testing costs, and opens more research and development 
                         opportunities for students involved in space area.",
