Well before the research flight phase, the Range Engineering Branch (Code MC) engineers and software developers build, integrate, and verify range assets. This is how they ensure the aircraft telemetry can be received and processed for control room display monitoring, that aircraft position can be tracked for situational awareness, and that control room voice communications are working, and, for unmanned aircraft, verify uplinks for command and control and flight termination systems. Code MC performs range systems engineering, test information engineering, and data processing and display system/software development.
