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.",
