| 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。

| Abstract: | 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. |
