The International Committee on Global Navigation Satellite Systems
7-11 November 2016, Sochi, Russia
The Eleventh Meeting of the International Committee on Global
Navigation Satellite Systems (ICG) was held in Sochi, Russia from 7 to
11 November 2016. The ICG has been formed as a result of recommendations
of the UN Committee on the Peaceful Use of Outer Space (COPUOS), as
ratified by the General Assembly of the UN. The International Federation
of Surveyors (FIG) is an Associate Member of the ICG. FIG Vice President
Mikael Lilje attended as the
FIG representative to UNOOSA. Unfortunately, Neil Weston could not be
present but he is FIG’s co-chair for Working Group D on Reference
Frames, Timing and Applications. This meeting attracted almost 150
people attended the meeting with representatives from all of the
GNSS/RNSS providers. There were also many representatives from other
countries and non-government organisations.
JOINT STATEMENT FROM ICG-11
At the end of each meeting, the ICG issues a Joint Statement
outlining the highlights of the broad scope of work across the ICG.
Various presentations were made at the plenary sessions and working
group sessions of the meeting and they form a very useful snap shot of
the state of the art with the various GNSS and also with issues across
key user groups. The Joint Statement from ICG-11, Working Group Reports
and all presentations are available on the ICG Information portal.

MAJOR FINDINGS FROM THE MEETING
There were many other presentations, discussions and decisions at the
meeting and the following is an outline of some that the author found
- Each provider presented on their status and their respective
- The FIG/IAG/ICG Technical Seminars are seen as successful and
useful. It was decided that ICG will continue with its support also
during 2017 with the technical seminar to be held in Kobe, Japan.
- The UN resolution on Global Geodetic Reference Frame for
sustainable development was presented and progress noted.
- The new ITRF realisation was presented by Zuheir Altamimi
- User perspective and applications describe through several
MEETINGS OF WORKING GROUP D AND ITS TASK FORCES ON GEODETIC AND
The working group had two meetings during the week. The minutes from
Working Group D and other Working Groups will be available from the ICG
web portal in due course as well as other official documents as e.g.
recommendations and all presentations.
The Working Group noted significant continued progress on the
geodetic and timing references by the ICG GNSS Providers. Specific
progress was noted: (1) the availability of the new release of the
International Terrestrial Reference Frame (ITRF2014) and the significant
contribution of GNSS data, (2) the refinement of the alignments of GNSS
associated reference frames to the ITRF, and (3) the information on the
GNSS timing references, the BIPM publications and the inter-comparisons
of GNSS time offsets.
Working Group D has contributed and will continue to contribute to
the IGMA initiative and in particular through the IGMA trial project and
the joint International GNSS Service (IGS) - IGMA Call for
The Working Group D noted lack of progress on two specific
recommendations, number 12 and 23: one in relation to the provision to
the IGS of GNSS data of Providers’ tracking stations, and one on the
possible provision by GNSS Providers of satellite data that would help
improving orbit modelling and accuracy. The Working Group D Providers
Members are solicited to follow up the implementation of the
