    Abstract: According to the ambient temperature requirements for the rubidium atomic clock, the paper presents the design of a small cabin for the rubidium atomic clock on a navigation satellite, and the method of precision temperature control. The flight data of the small cabin on the navigation satellite in GEO and IGSO are analyzed. The ambient temperature of the rubidium atomic clock can meet the requirements: -5~10 ℃. The stability of the ambient temperature control during the sun time is within 0.2℃/d. The stability of the temperature control for GEO satellites during eclipse time is within 0.8℃/d, and 0.3℃/d for IGSO satellites.
