Russia, India join global satellite-based augmentation meet

France: Experts ensuring that aircraft can safely rely on satellite navigation across Europe and other parts of the globe met in France to share future plans, welcoming Russian and Indian representatives for the first time.

Ever more aircraft around the globe are using satnav augmentation to guide them on their way, with special infrastructure sharpening signal accuracy and reliability across given geographical regions.

More than 50 of the specialists overseeing the world’s five regional satnav augmentation systems met at Toulouse in southern France for the latest meeting of the Satellite-Based Augmentation Systems (SBAS) Interoperability Working Group (IWG).

This gathering was the first to be attended by Russia’s space agency and the Indian Bureau of Civil Aviation, to discuss their own SBAS systems.

The meeting was jointly hosted by ESA’s European Geostationary Navigation Overlay System (EGNOS) and SBAS Division with the French space agency, CNES.

There’s satellite navigation and then there’s satellite augmentation – where additional ground monitoring stations and satellite transponders are used to sharpen satnav accuracy and reliability across geographical regions.

Today, there are three certified SBAS operational worldwide: Europe has EGNOS, designed and developed by ESA, operated by the European Satellite Service Provider and owned by the European Commission. EGNOS was made available for general users in 2009 and for aircraft landing approaches since March 2011.

The US has the Wide Area Augmentation System (WAAS), developed and operated by the Federal Aviation Administration (FAA), with an extension over Canada called CWAAS (Canadian WAAS).

Japan has the Multi-functional Satellite Augmentation System (MSAS), developed and operated by Japan’s Civil Aviation Bureau.
