International Committee on Global Navigation Satellite Systems (ICG)

The International Committee on GNSS (ICG) was established to promote the use of the GNSS infrastructure on a global basis and to facilitate the exchange of information. It is a unique structure dedicated to creating channels of communication between the service providers and numerous user communities.

The ICG was established on a voluntary basis as a forum for promoting cooperation, as appropriate, on matters of mutual interest related to civil satellite-based positioning, navigation, timing, and value-added services, as well as compatibility and interoperability among the GNSS systems, while increasing their use to support sustainable development, particularly in the developing countries.

The services the GNSS provide are essential for activities requiring timing and positioning. With the increasing number of independent systems, there is an increasing need for coordination to ensure they are interoperable and interchangeable, in order to meet the needs of all users.

The role of the BIPM at the ICG is to represent the interests of the time metrology community in particular, and to promote the regular use of metrology standards. Most actions of the BIPM happen within the Working Group D, Reference Frames, Timing and Applications.
