The method for estimating receiver P1-P2 DCB(Differential Code Bias) based on PPP technology is introduced.And P1-P2 DCB estimate of several IGS tracking stations distributing globally are calculated by the method.The results show that accuracy of estimated P1-P2 DCB is better than 1 dm in middle and high latitude area,and is about 1-2 dm in low latitude area.
