GNSS短边精度研究

The Accuracy Research of Short Baselines for GNSS

文章通过实验,掌握了GNSS短边测量的精度状况,结合电力工程测量相关规范要求,分析提出GNSS采用单时段观测,能够满足电力工程各种等级的施工控制网测量和三等及以下精度要求的水平位移监测需要,但不能满足各种等级垂直位移监测的要求。

Through experiments,the article concludes situations of surveying accuracy of short baselines for GNSS. Combined with the requirements of the relevant power engineering surveying regulatories, the article analyzes and puts forward a view. GNSS observation with single period can meet the requirements for the construction control network surveying of various levels in power engineering, and the requirements for the horizontal displacement monitoring of the third and less precision, but it can not meet the requirements for the vertical displacement monitoring of various levels.
