| Abstract: | 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.
