Abstract

In the recent years, a significant amount of the measurements of the Earth's ionosphere state has been made by medium- and high-orbit global navigation satellite systems (GNSS) such as GLONASS, GPS, Galileo, Beidou, SBAS, etc. Currently, a number of services (such as IGS, UNAVCO, CHAIN, CORS, etc.) provide GNSS data in open access in the RINEX format. The databases start from early 1990s. Currently more than 5700 GNSS sites provide ~ 1.5 Gb daily which is 200 millions independent data points. The software tools to deal with such amount of data become necessary to do research effectively. We have developed System for the Ionosphere Monitoring and Researching from GNSS (SIMuRG) for organizing RINEX data and analyzing results from geophysical research view point. This paper describes approaches to create SIMURG, as well as the opportunities that the system can provide to the scientific community.
工具创建地图的GNSS总电子含量变化
近年来,GLONASS、GPS、伽利略、北斗、SBAS等中、高轨道全球导航卫星系统(GNSS)对地球电离层状态进行了大量测量。目前,许多服务(如IGS、UNAVCO、CHAIN、CORS等)以RINEX格式提供开放获取的GNSS数据。数据库始于20世纪90年代初。目前,超过5700个GNSS站点每天提供约1.5 Gb的独立数据点。处理如此大量数据的软件工具对于有效地进行研究是必要的。我们开发了GNSS电离层监测与研究系统(SIMuRG),从地球物理研究的角度对RINEX数据进行整理和分析。本文描述了创建SIMURG的方法,以及该系统可以为科学界提供的机会。
