Currently, more than 6000 operating GNSS receivers deliver observations to multiple servers. Ionospheric data are derived from these measurements providing outstanding space coverage and time resolution. There are about 200 million independent measurements daily. Researchers need sophisticated software tools to deal with such a large amount of data. We present recent advances and products from the System for Ionosphere Monitoring and Research from GNSS (SIMuRG). Currently, SIMuRG provides the total electron content (TEC) variations filtered within 2–10 min, 10–20 min, and 20–60 min, the Rate of the TEC Index, the Along Arc TEC Rate index, and the vertical TEC. SIMuRG is an online service at http://simurg.iszf.irk.ru. The system can be used free of charge and allows calculating both maps and series for arbitrary time intervals and geographic regions. All the data products are available in the form of data or figures. We discuss the system and its geophysics applications.

SIMuRG：GNSS电离层监测和研究系统

当前，有6000多个正在运行的GNSS接收器将观测结果传送到多台服务器。电离层数据是从这些测量中得出的，可提供出色的空间覆盖范围和时间分辨率。每天大约有2亿次独立测量。研究人员需要复杂的软件工具来处理如此大量的数据。我们介绍了GNSS（SIMuRG）电离层监测和研究系统的最新进展和产品。当前，SIMuRG提供了在2-10分钟，10-20分钟和20-60分钟内过滤的总电子含量（TEC）变化，TEC指数的比率，沿弧TEC比率的指数和垂直TEC。SIMuRG是位于http://simurg.iszf.irk.ru的在线服务。该系统可以免费使用，并且可以为任意时间间隔和地理区域计算地图和序列。所有数据产品均以数据或图形的形式提供。我们讨论了该系统及其地球物理应用。
