More than 50 experts that oversee the world’s regional satnav augmentation systems met in Toulouse, France, last week for the Satellite-Based Augmentation Systems (SBAS) Interoperability Working Group (IWG). The meeting welcomed, for the first time, Russian and Indian representatives.

As satnav augmentation becomes widely used in aircraft around the globe, more regional systems are being developed for future certification by the International Civil Aviation Authority. This is the case for Russia’s System of Differential Correction and Monitoring (SDCM), lead by Roscosmos; and India’s GPS and Geo-Augmented Navigation (GAGAN) system, developed by the Indian Civil Aviation and the country’s space agency, ISRO. This was the first IWG that counted with these countries’ participation.

Eurocontrol, the European Organization for the Safety of Air Navigation, was also present at this IWG, jointly hosted by ESA’s European Geostationary Navigation Overlay System (EGNOS) and SBAS Division, and the French space agency, CNES.
