Abstract

当GPS应用于高精度变形监测时 ,其测定三维位移的精度和可靠性是人们最为关心的问题。本文从卫星星历、观测时段长度、基线长度和组成同步闭合环等多方面 ,对其基线解算的精度进行了全面客观的分析和评价 ,可为GPS用于精密工程测量和变形监测的方案设计提供参考||GPS technique is not only used for geodetic surveying,but also for high precise deformation monitoring,such as dams,bridges and landslides.In these high precise GPS applications,the great emphasize is put on 3-D relative positioning accuracy.In this paper,both the horizontal and the vertical accuracy of baseline solution are analyzed and evaluated among different ephemeredes,observation sessions,baselines lengths and network solutions.Some valuable results are summarized for high precise GPS engineering and deformation monitoring.
