GBC软件的精度分析

Precision analysis of GBC software

GBC是一款处理GNSS静态控制网数据的软件。为了验证其精度,本文以GBC与常用的三款软件TBC、LGO、SGO在基线平面精度、高程精度、基线长度、环闭合差和网平差结果等几方面进行了对比分析。对比结果表明GBC与国外知名软件TBC处理精度相当,完全满足石油勘探的需要。

GBC is a software for processing GNSS static control network data.In order to verify its accuracy,this paper compares GBC with three commonly used software TBC、LGO and SGO in the aspects of baseline plane accuracy,elevation direction accuracy,baseline length,loop closure error and network adjustment results.The results show that the processing accuracy of GBC is equivalent to that of TBC,which can meet the needs of petroleum exploration.
