The ESA Global Navigation Satellite System (GNSS) Science Advisory Committee (GSAC) is the senior advisory body to the Director of Navigation, acting as the Director General’s representative, on all matters concerning scientific exploitation of navigation programmes. It is the main interpreter of the views and needs of the European scientific community as regards uses of the GNSS programme for research in Earth, navigational and physical sciences.

Its main tasks are to advise and/or make recommendations on:

  • the needs of the scientific community for access to space for their research;
  • scientific activities during the definition, implementation and exploitation of the approved projects of the GNSS programme;
  • the formulation and updating of medium and long term GNSS policy in Europe in regard to the interests of the scientific community;
  • the priorities of the scientific community in the selection and formulation of future GNSS missions;
  • the scientific studies and activities required to lay the foundations for future missions, taking account of the recommendations of the Working Groups;
  • the selection of new scientific projects.
