摘要
通过应用东方地球物理公司自主研发的GBC软件,对其多星座数据的基线处理结果和网平差与TBC软件处理结果进行对比分析,可获得厘米级别的精度,满足物探测量规范的要求;另外,GBC软件网平差引入高精度的大陆速度场,实现动态网平差,为项目引入CGCS2000成果,建立项目基准提供了保证;其次PPK技术应用于测量项目生产,弥补了RTK作业的不足,为项目生产提供了强有力的技术保障。
By using the GBC software developed by BGP independently,the baseline processing results of Multi-constellation data and the network adjustment results are compared and analyzed with those of TBC software.The accuracy of centimeter level can be obtained,which meets the requirements of geophysical prospecting norms.In addition,GBC software network adjustment introduces high-precision continental velocity field to realize dynamic network adjustment,which guarantees the introduction of CGCS2000 achievements and the establishment of project benchmarks.The application of PPK technology in measuring project production makes up for the deficiency of RTK operation and provides strong technical guarantee for project production.
