The International Committee on Global Navigation Satellite Systems (ICG) promotes coordination among leading satellite operators and strives to maximize the benefits of global navigation satellite systems (GNSS) for sustainable development. ICG also serves as a platform for discussion and the exchange of information on general trends in user needs, applications and technology development. The Office for Outer Space Affairs of the Secretariat, as the executive secretariat of ICG, works with Member States to enhance the compatibility and interoperability of constellations of GNSS so that positioning, navigation and timing technology remains equally accessible to all.
ICG divides its work among four working groups comprising representatives of the members, associate members and observers of ICG. The following topics are currently being discussed by the working groups: systems, signals and services (Working Group S, co-led by the Russian Federation and the United States of America); enhancement of GNSS performance, new services and capabilities (Working Group B, co-led by China, India and the European Space Agency (ESA)); information dissemination and capacity-building (Working Group C, led by the Office for Outer Space Affairs); and reference frames, timing and applications (Working Group D, co-led by the International Association of Geodesy (IAG), the International Federation of Surveyors (FIG) and the International GNSS Service (IGS)).
The ICG Providers' Forum, consisting of those countries that operate global and regional navigation satellite systems or with plans to develop one, provides a venue for coordination and cooperation to improve overall service provision. The Forum also acts as a mechanism to continue discussions on important issues addressed by ICG that require inputs from system providers. The Forum meetings are held in conjunction with the annual meetings of ICG, or more often should the need arise.
The Fifteenth Meeting of the ICG, hosted by the United Nations Office for Outer Space Affairs (UNOOSA), will convene from 27 September through 1 October 2021 in the Vienna International Centre in Vienna, Austria
17 September 2020: In light of the Covid-19 pandemic, the meeting has been postponed to 27 September - 1 October 2021
