摘要
结合河道水利工程项目,通过RTK同一基准站连续重复测量同一地物特征点坐标和不同基准站重复测量地物特征点测试了其内部符合精度,还测试和研究了RTK定位时间与定位精度关系,通过对RTK定位结果与静态GPS控制测量、全站仪导线测量的结果进行对比分析,测试RTK定位的外部符合精度.从而得出RTK定位技术可应用于带状地形图根控制测量的结论.
Combining water conservancy projects and river course surveying,this paper conducts,through RTK,some testing over the internally coincident precision of the controlled surveying by repeated surveying of a same or different station.It also tests and analyzes the relation between RTK positioning time and positioning precision.And by means of contrasted analyses of the result of RTK poisoning,the result of the static GPS controlled surveying and the result of total-station surveying,the paper further tests the externally coincident precision through RTK.Thus,a conclusion is obtained that RTK positioning technology can be applied to the controlled surveying for strip-topographic mapping.
