Abstract: A new kind of hydrogen-ma ser time and frequency Standard was installed this September at sheshan 25-meter radio telescope in Shanghai, for very long baseline interferometry (VLBI) experiments. This standard is a readily transportable, rugged and completely integrated frequency standard. The entire system is engineered as a unit, and all electronics were mechanically and electrically integrated with the physical portion into the overall design. This paper describes its design feature and structure as well as the measured results of its performance. Its applications and data in VLBI experiment are also included.
