TSAs focus on telemetry signals used in the defense industry that includes spacecraft monitoring, aircraft development, and weapons system testing. Telemetry is used by manned and unmanned spacecraft for various data transmissions including monitoring the health of astronauts as well as the health and status of the actual spacecraft. Telemetry for weapons testing includes monitoring temperatures, vibrations, accelerations, positions and status of various subsystems. Telemetry is also used for range safety related to flight testing to determine flight termination criteria. The role of a TSA is to reverse engineer the telemetry data transmitted by various systems to determine the performance characteristics and capabilities of these systems.
