The field of interest of the IEEE Aerospace and Electronic Systems Society (AES-S) is the design, integration, test, and analysis of large, complex systems consisting of major subsystems that contain dissimilar electronic devices. Its members work on telemetry systems, sensor systems— such as radar, guidance, and navigation—, avionics, space systems—including manned and unmanned vehicles and communication satellites—, military systems, power systems, and auto-test systems. As such, it is one of the broadest IEEE Technical Societies. It also has perhaps the most complex history of any Technical Society. The Society began exactly 50 years ago, when a group of radio engineers got together to organize conferences on technological issues that had grown out of World War II aerial warfare and then formed the Professional Group of Radio Telemetry and Remote Control of the Institute of Radio Engineers.
