摘　　要：北斗卫星导航系统2012年底已能满足亚太地区的导航定位需求。文章针对相对定位模式,给出了GPS/BDS组合定位的伪距相对定位和载波相位相对定位模型,并通过实测数据的精确处理对北斗系统的可用性及GPS/BDS组合能达到的精度进行分析,验证了GPS/BDS组合系统相对定位模型的正确性,为北斗系统的推广应用提供了参考。BeiDou Satellite（BDS）navigation system has been able to meet the needs of navigation and positioning in the Asia-Pacific region by the end of 2012.In this paper,directing at the relative positioning mode,the relative positioning models of pseudo-range and carrier phase for GPS/BDS combined positioning were given.Finally,it analysed the availability of BDS system and the accuracy of GPS/BDS combined positioning by the observations results of test data.The feasibility of the combined models was verified,and the result would provide a reference to the promotion and application of the BDS.
