基于Anubis多模多频GNSS数据质量检核性能验证与分析

Verification and Analysis of Quality Check Performance for Multi-mode Multi-frequency GNSS Data Based on Anubis

针对传统主流软件难以对多系统、多模多频混合全球卫星导航系统(GNSS)数据进行全方位多层次质量检核,尤其是对北斗卫星导航系统(BDS)等新兴系统不支持的问题,引入阿努比斯(Anubis)软件。在分析其主要功能及使用方法的基础上,通过与主流软件进行全方位对比,利用其与数据格式转换、元数据编辑及数据质量检查(TEQC)软件分别对实测数据进行质量检核和性能分析,并根据其在不同定位环境下的性能表现,验证其可用性。实验结果表明Anubis数据质量检核结果与TEQC相当,但对各数据质量指标的分析在统计上更加细化。其对不同环境下的多系统数据反应灵敏,可用性强。

Aiming at the problem that traditional software cannot perform all-round quality check on multi-system data,especially for the data of new systems like BeiDou navigation satellite system(BDS),this paper introduces the Anubis software,with its function and usages given.Comparing with the mainstream software in an all-round way,quality check performance analysis on measured data is performed using Anubis and TEQC,and the availability is verified based on its performance in different environments.The results show that Anubis gets comparable data quality check results to TEQC,and its analysis of various data quality indicators is statistically more detailed.It is sensitive to multi-system data in different environments and has strong usability.
