摘要
就GPS精密数据处理工作中的基准统一方法进行了探讨,陈述了基线处理时统一基准和平差处理时统一基准的基本原理,通过案例分析了两种不同基准统一方法所得到的三维速度估值的差异,建议在现今地壳运动速度场研究工作中,采用第二种方法进行GPS精密数据处理。
Datum unity in GPS precise data processing was discussed in this paper. Theories of unifying datum in baseline processing and adjustment processing were declared respectively, and the difference of 3D speed valuations calculated by those two methods was analyzed by case study. As a result, the second method was recommended to process GPS precise data in present-day crustal movement velocity field research.
