【摘要】 在ＧＰＳ定位测量逐步发展的今天．用ＧＰＳ控制点发展较低等级的导线已势在必行。根据ＧＰＳ控制点的布设特点，讨论能否在ＧＰＳ点间发展精度满足小地区不同要求的导线是文章的写作宗旨。文章通过对ＧＰＳ点间缺少方位角条件导线的分析，探讨了使其精度提高的相应方法，论证了在ＧＰＳ点间敷设缺少方位角条件的导线对满足小地区不同要求的测量工作是切实可行的。更多还原

【Abstract】 Today it is necessary that using GPS control points develops lower hierarchical traverses. Considering the laying characteristic of GPS control points,discussing if it is possible to lay defferent precision traverses between GPS control points is the purpose of this paper.Through analysing the traverses of lacking azimuth condition, this paper has put forward the corrosponding methods that can make their precison higher. Meanwhile it has shown the feasiblity that we can lay this kind of traverse between GPS control points.更多还原
