3. Antenna System Improvements 3.1 34-m Antenna System Improvement

摘要

The Kashima 34-m antenna was manufactured by TIW Systems (now VertexRSI) in the United States and constructed in 1987 as the main station of the Western Pacific VLBI Network. For more than thirteen years, the radio telescope has been used for both geodetic VLBI and radio astronomy. Its control system is continuously being improved to provide better performance. This paper reports on past improvements and technical enhancements to the 34-m antenna system with a focus on hardware.
