Infrastructure

The EGNOS infrastructure is comprised of:

  • a ground network of 40 ranging and integrity monitoring stations (RIMS)
  • 6 navigation land earth stations (NLES)
  • 2 mission control centres
  •  signal transponders on 3 geostationary satellites (Inmarsat III satellite, and SES ASTRA GEO satellites SES-5 and ASTRA-5B).

Governance

EGNOS is owned by European citizens. The European Commission took over ownership of the EGNOS infrastructure from the European Space Agency (ESA) on behalf of the European Union on 1 April 2009. Since 1 January 2014, the exploitation of EGNOS has been fully delegated to the European GNSS Agency (GSA) by the European Commission.
