摘要
通过对不同长度GNSS导线实测数据的处理比较,分析了GNSS基线走向变化对点位精度的影响。结果表明,GNSS支导线中各控制点在经度、纬度和高程方向的误差累积与基线走向有关,并随点位经纬度的变化呈现一定的规律。
By comparing processing results from observing data of GNSS open traverse with different lengths,the analyses are detailed about traverse direction＇s influence on point location＇s precision.The experiment shows that control points＇ error accumulations not only have intrinsic relationships with traverse direction lying in longitude,latitude and altitude,but also satisfy some certain regulation along with variations of longitude and latitude.
