The development of three SATCOM on-the-move (SOTM) terminals designed to operate on the Wideband InterNetworking engineering test and Demonstration Satellite is discussed. All three terminals were able to achieve a tracking error of less than 0.2° and uplink data rate of at least 9 Mbps when operated under worst-case motion. Key design choices and improvements between the earliest and later designs are presented.
