Development of a New Type of Spaceborne Miniaturized Rubidium Clock

Spaceborne rubidium clock has been widely used in the fields of navigation satellites, remote sensing satellites, and so on. With the continuous expansion of application fields, spaceborne rubidium clock miniaturization put forward higher requirements. This paper introduces a new type of miniaturized spaceborne rubidium clock. By optimizing the design, performance reached the level of similar foreign rubidium clock (3E-12/1s). The whole mass of the clock is less than 1.5 kg, half of the similar foreign clock, the Volume is less than 2L.
