摘　　要：通过差分技术能够消除GPS伪距中大部分公共误差,同时能够较为准确的计算出基线两端的GPS接收机间的相对位置关系。本文介绍了基于GPS伪距双差的相对定位方法,在此基础上开展了GPS伪距差分相对定位试验分析,比较了单频伪距双差与窄巷伪距双差的相对定位精度。试验表明,窄巷伪距双差相对定位具有更高的相对定位精度。The majority of common errors of GPS pseudo-range could be eliminated through differential technology.Meanwhile,the relative positioning of the two receivers would be acquired.The article introduces the method based on GPS pseudo-range double differential firstly,and then the trial of relative positioning was conducted in which the accuracy of using the single frequency and narrow-lane pseudo-range were compared.The results show that the using of the narrow-lane pseudo-range provides the highly relative position accuracy.
