英文摘要	Due to the shadowing in the urban environment, the GNSS receiver positioning accuracy is poor which is unable to meet the critical applications in vehicle network. To meet the accuracy of relative positioning in critical vehicles application, a variety of wireless ranging methods is being applied to the vehicle navigation. However, they not get the direction information between cars. In this paper, a method that combines wireless ranging and difference pseudorange is presented. This method increase the accuracy of direction information in the relative positioning and can be implemented in the case of only 2-3 shared satellites which expand the cooperation positioning application. Compared with traditional method, the variance of Azimuth is reduced by 50 %.; Engineering, Electrical & Electronic; Telecommunications; EI; CPCI-S(ISTP); 0
