Lower frequency bands allocated for satellite communications use are becoming saturated due to steadily increasing demand. An ongoing program to develop the new technologies required to meet the demands of future systems is described. Higher frequency components and more efficient system techniques are developed. In order to accurately evaluate the performance of these technologies, an automated test system was designed and built. The automated system's design an capabilities are discussed
