Dataset accompanying article: On Linear and Circular Approach to GPS Data Processing: Analyses of the Horizontal Positioning Deviations Based on the Adriatic Region IGS Observables

The dataset accompanies journal article: On Linear and Circular Approach to GPS Data Processing: Analyses of the Horizontal Positioning Deviations Based on the Adriatic Region IGS Observables published on 21 January 2021 in Data.  

SINEX, RINEX, position solution files, logs used for positional accuracy and deviation distribution of IGS observables and additional figures with results are included. Dataset covers period from 10th to 20th of March 2017. 

IGS SINEX combined weekly station position/velocity solutions were retrieved from  the online archives of the Crustal Dynamics Data Information System (CDDIS), NASA Goddard Space Flight Center, Greenbelt, MD, USA, available at: ftp://cddis.nasa.gov/gnss/products/. Please note that from from October 31, 2020 anonymous ftp service has been discontinued. Access with examples is available via HTTPS or ftp-ssl from CDDIS Archive

RINEX observation and navigation files were retrieved from IGS repository available at: ftp://igs.ign.fr/pub/igs/data/

Position solution files were determined with RTKLIB: An Open Source Program Package for GNSS Positioning, version 2.4.3 b33 available

本数据集配套发表于2021年1月21日《数据（Data）》期刊的学术论文《GPS数据处理的线性与循环方法：基于亚得里亚海区域IGS（International GNSS Service）观测值的水平定位偏差分析》。

本数据集包含用于分析IGS观测值定位精度与偏差分布的SINEX、RINEX、定位解算文件、日志文件，以及附带结果的补充图表。数据集覆盖的时间范围为2017年3月10日至20日。

IGS联合周度测站位置/速度解算的SINEX数据取自美国马里兰州格林贝尔特市美国国家航空航天局（National Aeronautics and Space Administration, NASA）戈达德太空飞行中心的地壳动力学数据信息系统（Crustal Dynamics Data Information System, CDDIS）在线存档，获取地址为：ftp://cddis.nasa.gov/gnss/products/。请注意，自2020年10月31日起，匿名FTP服务已停止运行，可通过HTTPS或FTP-SSL访问CDDIS存档并获取使用示例。

RINEX观测与导航文件取自IGS存储库，获取地址为：ftp://igs.ign.fr/pub/igs/data/

定位解算文件通过RTKLIB（一款用于GNSS定位的开源程序包，版本为2.4.3 b33）生成，该程序包可公开获取。
