本文根据2002年4月8日至11日在加拿大渥太华举行的2002年IGS网络、数据和分析中心研讨会上提出的立场文件，介绍了IGS电离层工作组（Iono_WG）。有关IGS的详细信息，一般可以在IGS中央局网页上找到： http://igscb.jpl.nasa.gov .该工作组于1998年6月开始工作。该工作组目前的主要活动是例行制作时间分辨率为2小时的电离层总电子含量图和每日的全球定位系统卫星和接收器硬件差分码偏差值。TEC图和DCB集来自全球IGS跟踪网络记录的全球定位系统双频跟踪数据，从中长期来看，工作组打算完善根据全球定位系统测量绘制电离层参数图的算法，并实现IGS电离层产品的近实时可用性。本文件将概述该工作组的活动，其中包括工作组自成立以来的活动摘要、成就和未来计划。
This article is based on a position paper presented at the IGS Network, Data and Analysis Center Workshop 2002 in Ottawa, Canada, 8–11 April 2002, and introduces the IGS Ionosphere Working Group (Iono_WG). Detailed information about the IGS in general can be found on the IGS Central Bureau Web page: http://igscb.jpl.nasa.gov . The Iono_WG commenced working in June 1998. The working group's main activity currently is the routine production of ionosphere Total Electron Content (TEC) maps with a 2-h time resolution and daily sets of GPS satellite and receiver hardware differential code bias (DCB) values. The TEC maps and DCB sets are derived from GPS dual-frequency tracking data recorded with the global IGS tracking network.In the medium- and long-term, the working group intends to refine algorithms for the mapping of ionospheric parameters from GPS measurements and to realize near–real–time availability of IGS ionosphere products. The paper will give an overview of the Iono_WG activities that include a summary of activities since its establishment, achievements and future plans.
