Evolution of Ka-Band On-the-move Terminals for Land and Maritime Broadband Communications
Evolution of Ka-Band On-the-move Terminals for Land and Maritime Broadband Communications
The development of three SATCOM On-the-move (SOTM) terminals designed to operate on the WINDS satellite is discussed. All three terminals were able to achieve a tracking error of less than 0.2 degrees and uplink data rate of at least 9Mbps when operated under worst case motion. Key design choices and improvements between the earliest and later designs are presented.
