Abstract
Aiming at the influence of inter-system bias (ISB) on the accuracy of undifferenced FCB. This paper estimates three different FCBs (WN-FCB, RW-FCB, CV-FCB) based on white noise, random walk, constant strategies. And using the three FCBs to fixed ambiguity. The experimental results show that: in the wide-lane FCB, the accuracy of three wide-lane FCB products is equivalent; in the narrow-lane FCB, compared with narrow-lane CV-FCB, the precision of RW-FCB and WN-FCB is equivalent, better than CV-FCB. For the convergence time and positioning accuracy, PPP-AR based on RW-FCB and WN-FCB is significantly better than CV-FCB.
