摘要: 本文针对国内常用的三款商业软件中海达HGO软件、华测CGO软件、和南方GNSS数据处理软件进行研究,在截止高度角和采样频率等参数相同的情况下,对三种软件基线解算的质量、网平差后的点位精度、以及相同基线在GPS系统和北斗系统下的计算结果进行了对比和分析。实验表明,三种软件都较为成熟,并满足D级GPS控制网工程的精度要求;HGO软件对基线向量和网平差的处理结果要略优于另两种软件。

Abstract: In recent years, the development of BDS has greatly promoted the evolution and progress of the domestic GNSS data processing software. In this paper, three commercial softwares including HGO, CGO and South GNSS software have been studied by keeping the threshold elevation angle and sampling frequency the same, the quality of baseline calculation, the position accuracy after netadjustment, and the baseline processing results under BDS and GPS are compared and analyzed. Experiments show that the three commercial softwares are relatively mature, and can meet the D grade GPS control network engineering measurement accuracy requirements. The results of the baseline vector and net adjustment by HGO software are slightly better than the other two kinds of softwares.
