Chapter 35 Development of New-Generation Space-Borne Rubidium Clock

摘要

Beijing Institute of Radio Metrology and Measurement began to develop space-borne rubidium clocks from 2000. As one of the manufacturers of space-borne rubidium clocks, the institute had delivered more than 10 products to a satellite system of China until 2011, greatly supporting the construction of the satellite system. This paper summarizes the design features and performances of its previous products. The institute started to develop the new-generation space-borne rubidium clock in 2011. By using a series of new techniques, a prototype has been built. Compared to the previous products, the performance of the prototype is greatly improved. This paper also discusses the main differences between the previous and current products, both in design and in performance.
