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。
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 commer- cial 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 calcu- lation, 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.
