000193379 5203_ $$9eng$$ahe International GNSS Service (IGS), a federation of 200+ international agencies, pools GNSS measurements, data-processing facilities and scientific expertise to generate the highest-possibleaccuracy positioning, timing and geophysical estimates in support of science research needs. One of its major activities is to coordinate the continuous acquisition of GNSS measurements at 400+ carrier-phase GNSS receivers worldwide. Among the geophysical quantities of interest to the IGS is the excess path delay encountered by GNSS signals as they traverse the lower part of the atmosphere, the troposphere, en route to these receivers. The IGS conducts two troposphere-related programs: production of IGS Final Troposphere Estimates and operation of the IGS Troposphere Working Group. These activities have since 2011 been coordinated by the US Naval Observatory (Washington, DC). In this paper we provide an overview of the IGS, review the production/applications of IGS Final Troposphere Estimates, and
