摘　　要：在GPS大规模变形监测的应用中,为了获取高精度的GPS监测点坐标值往往需要联合周围IGS跟踪站并利用精密基线解算软件求解监测网点基于ITRF框架下的精确坐标;分析了影响GPS监测网平差精度的因素,并对作为基准点的IGS跟踪站进行了稳定性分析。结合某大面积矿区GPS监测网的实测数据,设计了两种固定不同基准点的方案分别利用Bernese5.0软件解算其基于ITRF2005框架下的坐标,结果表明:合理地选择周围的IGS跟踪站可以作为大范围变形监测的基准点。In order to obtain precise GPS coordinate, it is in great need of combination IGS tracking stations around the monitoring area and using sophisticated GPS software to solve the coordinates of the monitoring network under International Terrestrial Reference Frame （ITRF） ; Factors which impact the precision of GPS deformation monitoring network adjustment are analyzed, and the stability of IGS tracking station, as reference point, is probed. Finally, a concrete example based on the observation data of large-scale GPS moni- toring network, was processed using BerneseS. 0 software according to two different schemes respectively, and the coordinates of whole points was obtained for two sessions under ITRF2005; The results show that If the IGS tracking stations around the large-scale deform-ation monitoring area are selected reasonably, they can be used as reference points.
