N2 - The aim of this article is to improve the method of network RTK based on undifferenced (UD) observation corrections (abbreviated as URTK hereafter) by modeling the code UD observation residual. Thus rover could obtain more accurate approximate coordinate by code Single Point Positioning (SPP), and then, speeding up the ambiguity convergence time. In addition, based on the improved URTK method, a three-step method for single-differenced (SD) ambiguity resolution of rover is proposed, which could solve the ionosphere-free (LC) ambiguities in several seconds. Lastly, based on the existing network RTK software and the real-time data stream simulator, the efficiency of our new methods have been proved with a real-time test. The results show that rover could gain rapid, cm-level and real-time Precise Point Positioning (PPP) service using CORS network.
