To improve the accuracy of the rubidium clock frequency to provide the atom frequency standard with high accuracy, after analyzing the existing approaches to disciplined rubidium clock, an approach based on GPS/BDS common view technology is put forward in which the output frequency of rubidium clock is disciplined to UTC(NIM) and the existing problem of low accuracy of the old method in which the rubidium frequency is directly disciplined to the satellite carried atom clock is overcome. In addition, to expend the applied range of the BDS and maintain our independent position in time frequency metrology, BDS and GPS patterns are compatible in the system design. The experiments show that the approach based on the common view technology can realize the disciplined rubidium clock effectively, and the rubidium clock frequency accuracy, 5e-11, is improved to 1.62133e-14 and 1.36395e-14 by three orders of magnitude with GPS and BDS patterns respectively and the caesium clock level is reached.
