关 键 词：Pseudorange difference Direction method Cooperation position
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 *** meet the accuracy of relative positioning in critical vehicles application,a variety of wireless ranging methods is being applied to the vehicle ***,they not get the direction information between *** this paper,a method that combines wireless ranging and difference pseudorange is *** 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 *** with traditional method,the variance of Azimuth is reduced by 50%.
