一种多GNSS的数据质量检测工具——Anubis

A Toolkit of Detecting Multiple GNSS Data——Anubis

介绍了一种由GOP（Geodetic Observatory Pecny）机构研发的GNSS（global navigation satellite system）的开源数据质量检测工具——Anubis,与传统质量检测工具相比,该工具不仅能对观测文件和导航文件进行质量检核与统计,还可以利用三频数据进行周跳探测与修复,实时钟跳探测与修复,多频多信号的多路径探测,以及更高精度的SPP等功能。此外,该工具还有强大的可视化绘图功能。本文介绍了Anubis工具的主要功能,并给出了MGEX站数据的检测结果,验证了该工具的可行性以及其强大数据检测功能。

Checking data quality is the priority work of the post-processing.With the rapid development of multi-satellite navigation system,the traditional data detection tools,such as TEQC,GFZRNX and BNC,have been unable to meet need.So we present a multi-GNSS open source data quality checking tool developed by the GOP（Geodetic Observatory Pecny）.Compared to traditional checking tool,the tool can not only obtain quality inspection and statistics for observation files and navigation files,but also can realize cycle slip detection and repair,real-time clock slip detection and repair,multi-frequency signal multipath detection,and more accurate SPP with the help of tri-band data.In addition,the tool has a powerful visual graphics function.The main functions and algorithms of Anubis tool are elaborated,and the results of MGEX station data are given to verify the feasibility of the tool and its powerful data-detection ability.
