Abstract The prediction precision of receiver clock bias (RCB) is an important factor in influencing the receiver autonomous integrity monitoring (RAIM) method augmented with it and improving GPS receiver positioning precision. According to the characters of the RCB series, a new prediction model in discrete grey form is presented in this paper, and then the initial value of the model is determined by establishing unconstrained optimised formula. The prediction model is utilised to augment RAIM method in order to identify faulty satellite and improve the positioning precision of GPS receiver. Experimental results show that the prediction model is fit for predicting the RCB series, and the RAIM method aided by it is feasible. The auxiliary RAIM method can not only enhance the efficiency of identifying faulty satellite, but also improve the positioning precision of GPS receiver obviously.

    Highlights ► The prediction model for the series of receiver clock bias in discrete grey form is presented. ► The initial value of the model can be determined by establishing unconstrained optimised formula. ► The auxiliary RAIM method aiding of the prediction model can improve the GPS positioning precision.
