The foreseen specifications for determined equipment can be proved by the results provided in accomplishment of specific tests. The tests accomplishment is a task that follows development cycle of systems applied to space segment. The electrical and electronic equipment that are part of sounding rockets electrical networks and satellite launcher vehicles, currently developed by Space and Aeronautical Institute, are typically submitted to qualification and / or acceptance and / or revalidation tests. Those tests are carried out by a specialized technical team that performs a long sequence of activities. Those activities require, from the team members, constant visual evaluations, annotations, and interventions in parts that compound the assembled sets to support any type of test. With a goal of minimizing time and the human efforts, in the accomplishment of those activities, it was opted to automate part of aforementioned tests. Within that context, this work presents a system architecture proposal to automate the tests of modules, which perform safety and switching tasks, inserted in the electrical networks of those sounding rockets electrical and satellite launcher vehicles. That system architecture was designed to be applied in a specific family of satellite launcher vehicles, based on supervision system, programmable logic controller, sensors and actuators, available in national market, with a goal of taking advantage of, mainly, utilization of standard hardware and software that have capability to accomplish modifications in integrated development environment. The satisfactory results observed in the operational tests, performed with the first representative prototype version of that architecture, indicated that such proposal presented in this work is feasible, and it is able to comply with proposed target.
