Abstract: The theory of frequency calibration and the error analysis for rubidium frequency standard are introduced. A scheme based on multi-reference Source for frequency calibration is presented, can calibrate frequency from GNSS/BEIDOU receicer’s 1PPS/IRIG-B(DC) code and primary frequency standard’s 10MHz ,can meet users’ demands about calibration time and the accuracy by selecting different calibration time as 100s、1 000s and 10 000s.

Key words: Rubidium, Frequency standard, Frequency calibration, Multi-reference source
