GBC与TBC软件多星数据处理结果的比较

Comparisons between GBC and TBC in processing multi-satellite data

本文采用东方地球物理公司自主研发的GBC和国外的TBC软件,对青海冷湖三号项目的 GNSS控制网观测数据,采用单卫星和组合卫星的方式,设置相同的处理条件,处理基线和网平差,详细比较了GBC与TBC的处理结果。其中GBC的基线处理结果与TBC的差值平均小于3cm,网平差结果与TBC的差值平均平面小于1cm,高程大约为2cm。GBC处理结果与TBC的结果一致,是可靠的,符合石油勘探相关规范。

Using GBC and TBC software developed independently by Eastern Geophysical Company and foreign countries,the GNSS control network observation data of Qinghai Lenghu No.3 project are processed by single satellite and combined satellite under same processing conditions,same process baseline and network adjustment.Then the processing results of GBC and TBC are compared in detail.The difference between GBC baseline processing results and TBC is less than 3 cm on average.The difference between network adjustment results and TBC is less than1 cm in average plane and about 2 cm in elevation.The results of GBC processing are consistent with those of TBC,which shows that the method is reliable and conforms to the relevant specifications of petroleum exploration.
