An efficient technique to facilitate GPS single frequency phase ambiguity resolution

YANG Ren-gui,OU Ji-kun,WANG Ai-shengi(Institute of Geodesy and Geophysics,Chinese Academy of Sciences,Wuhan 430077,China)  
Aiming at the difficult problem of fixing the integer cycle ambiguities for GPS single frequency phase,the paper with the methods of the theory analyzing and experiments validating,deduces the recurrence formula for carrier phase smoothing pseudo-range in the real-time kinematic mode,proposes some approaches to increase the accuracy of the initial values used by the observation equation linearization.Based on the analyses of the structure characteristics of the double difference equation,a new approach that uses the iterative fitting method by selection of the parameter weights to improve the precision and the reliability of the computed float ambiguities is suggested,which reduces the search space for integer ambiguities,raises the efficiency and the success rate in the course of fixing integer ambiguities and promotes the applications of single frequency GPS receiver in the high precision fast positioning.
