Assembly, Integration, and Testing (AIT)
The purpose of the AIT subsystem is to bring together all the subsystems. Each subsystem has different technologies and ideas, and these must be compatible with the overall design of the satellite. AIT also verifies that the design parameters and program requirements are met. AIT assembles the final satellites inside a cleanroom. Before and after the final assembly, high-level testing takes place to ensure the operability of the satellite.
